+#+filetags: :microlise:security:notes:
+
+* Metadata
+
+- Name :: Understanding Session XSS
+- Overview :: Pages 33–34 document an informational “Session stored XSS” finding on the TMC Schedule Execution Board. The issue is real (unescaped user input in a JavaScript context) but impact is limited because only the submitting user’s session is affected—classic self-XSS, not cross-user attack.
+
+** Todos
+
+- [X] review-finding :: Read pages 33–34 and map finding to SaveSearchCriteriaToSession + ScheduleExecutionBoard.aspx flow
+- [X] locate-source :: Open TMC Web Portal repo and find session save + inline script render for date/orderID/time
+- [ ] remediate-encode :: Apply HttpUtility.JavaScriptStringEncode to all session values in SetupControls() (~1849-1879)
+- [ ] remediate-validate :: Add server-side validation in SaveSearchCriteriaToSession before writing SEBSessionState
+- [ ] remediate-retest :: Retest with direct POST payload + normal UI search flow on ScheduleExecutionBoard
+
+* Understanding the Session Stored XSS Finding (Pages 33–34)
+
+** Where this sits in the report
+
+The [[file:d:/_dev/_misc/Pentest-04-26/Microlise TMC PO WA April 2026 v1.0.pdf][Microlise TMC PO WA April 2026 v1.0.pdf]] lists *14 findings* total. Pages 33–34 ([[file:d:/_dev/_misc/Pentest-04-26/33-34.pdf][33-34.pdf]]) are the last technical finding before “END OF DOCUMENT”:
+
+| Field       | Value                                                                 |

+| Severity    | *Informational* (lowest tier; 4 informational findings in the report) |
+| Status      | Open                                                                  |
+| CWE         | [[https://cwe.mitre.org/data/definitions/79.html][CWE-79]] — Improper Neutralization of Input                             |
+| Environment | =cert.microlise.com= (cert/UAT), path prefix =/PENTEST/TMCWebPortal/= |
+
+Higher-severity items in the same report (SQLi, IDOR, BFLA, etc.) are separate; this finding is documented as *technically valid but low business risk*.
+
+-----
+
+** What XSS is (general)
+
+*Cross-Site Scripting (XSS)* means untrusted data ends up in a web page in a way the *browser treats as executable JavaScript*, instead of inert text.
+
+#+begin_src mermaid :exports none
+sequenceDiagram
+    participant Attacker
+    participant App as WebApplication
+    participant Victim as VictimBrowser
+
+    Attacker->>App: Submit malicious input
+    App->>App: Store or reflect input
+    App->>Victim: HTML/JS page containing payload
+    Victim->>Victim: Browser runs attacker's script
+    Note over Victim: Script runs with the site's origin<br/>can access cookies, DOM, APIs
+#+end_src
+
+The name “cross-site” is historical: classic attacks trick a *victim* into loading a page on *your* app so script runs in *your* origin (stealing session cookies, performing actions as the user, etc.).
+
+Common types:
+
+| Type        | Persistence                           | Typical delivery                 |
+|-------------+---------------------------------------+----------------------------------|
+| *Reflected* | Not stored; one-off response          | Malicious link/query param       |
+| *Stored*    | Saved server-side (DB, file, session) | Victim loads a normal page later |
+| *DOM-based* | Client-side only                      | Unsafe innerHTML, eval, etc.     |
+
+*Defense in depth:* validate input on the server (whitelist formats), and *encode output* for the exact context (HTML, attribute, JavaScript string, URL).

+    A --> B --> C
+    C --> D --> E --> F
+#+end_src
+
+1. *Save:* User (or tester) POSTs JSON to =SaveSearchCriteriaToSession=. The app saves search criteria into the *server-side session*.
+2. *Render:* On the next load of =ScheduleExecutionBoard.aspx=, those values are written into the HTML *inside a =<script>= block*, as JavaScript string literals.
+3. *Bug:* Values are inserted *without JavaScript string encoding*. A crafted =date= can *break out of the string* and run arbitrary JS.
+4. *Proof:* Pentesters confirmed execution in the browser; screenshots in the PDF show the POST and page source.
+
+*** Code path (matches report exactly)
+
+*1. Save — no server-side validation*
+
+#+begin_src csharp
+// ScheduleExecutionBoard.aspx.cs lines 336-348
+[WebMethod]
+public static void SaveSearchCriteriaToSession(string searchID, string orderID, string date, string time, int hours, bool displayPriorityJourneys, string quickSearch)
+{
+    var sebState = new SEBSessionState();
+    sebState.ComplexSearch = searchID;
+    sebState.OrderBy = orderID;
+    sebState.SearchDate = date;
+    sebState.SearchTime = time;
+    // ...
+}
+#+end_src
+
+*2. Persist — per-user ASP.NET session*
+
+[[file:d:/_dev/WebPortal/src/code/AmberWebUI/SEB/SEBSessionState.cs][SEBSessionState.cs]] stores values under keys =dateID=, =timeID=, =orderByID=.
+
+*3. Load — on next full page GET*
+
+#+begin_src csharp
+// ScheduleExecutionBoard.aspx.cs lines 267-277
+private void SetupControls()
+{
+    var sebState = new SEBSessionState();
+    SessionOrderID = sebState.OrderBy;
+    SessionDate = sebState.SearchDate;
+    SessionTime = sebState.SearchTime;
+    // ...
+}
+#+end_src
+
+*4. Render — vulnerable inline JavaScript (root cause)*
+
+#+begin_src javascript
+// ScheduleExecutionBoard.aspx lines 1853-1875
+if ("<%=SessionDate%>") {
+    $('#txtStart').val("<%= SessionDate %>");
+}
+if ("<%=SessionTime%>") {
+    $('#inputtime').val("<%=SessionTime%>");
+}
+if ("<%=SessionOrderID%>") {
+    $(orderBySelector + ' option[value="<%=SessionOrderID%>"]').attr('selected', 'selected');
+}
+#+end_src
+
+Example payload in session: ="); alert(document.domain); //=
+
+#+begin_src javascript
+$('#txtStart').val(""); alert(document.domain); //");
+#+end_src
+
+*Related:* =QuickSearch= at line ~1879 — fix in the same pass.
+
+*** Why “stored”, “session”, and “self-XSS”
+
+- *Stored:* Payload survives page navigation in *session state*.
+- *Self-XSS:* Only the submitter’s session is affected; no normal cross-user path.
+- Severity *Informational* because threat model is weak vs shared stored XSS.
+
+*** Client vs server validation gap
+
+Pentesters bypassed browser validation via direct POST. No server-side validation blocked arbitrary strings.
+-----
+
+** Replicating the vulnerability (hands-on)
+
+Use this section to *see the bug work* on an authorized environment (e.g. cert/UAT), then *repeat the same steps after fixes* and compare outcomes.
+
+*** Prerequisites
+
+| Requirement     | Detail                                                               |
+|-----------------+----------------------------------------------------------------------|
+| *Authorization* | Pentest scope or internal security test policy only                  |
+| *Permission*    | =Microlise:TMC:SEB:Read=                                             |
+| *URL*           | e.g. =https://<host>/TMCWebPortal/SEB/ScheduleExecutionBoard.aspx=   |
+| *Tools*         | Browser + DevTools or Burp Suite                                     |
+| *Build*         | Before-fix build first; redeploy with remediation for after-fix runs |
+
+Must be logged in (valid session cookie on POST).
+
+*** What you should observe (before fix)
+
+#+begin_src mermaid
+sequenceDiagram
+    participant You as Tester_browser
+    participant API as SaveSearchCriteriaToSession
+    participant Sess as ASP.NET_session
+    participant Page as ScheduleExecutionBoard_GET
+
+    You->>API: POST JSON with malicious date
+    API->>Sess: Store raw date in session
+    You->>Page: Reload SEB page
+    Page->>You: HTML with unescaped date inside script
+    You->>You: alert or other JS runs
+#+end_src
+
+1. WebMethod returns HTTP 200.
+2. Payload never went through =DateValidation()=.
+3. Full page reload → JS runs (e.g. =alert=).
+4. View Source: payload inside double-quoted JS string, unescaped.
+
+*Self-XSS:* only your session is poisoned.
+
+*** Step-by-step reproduction
+
+*Step 1 — Baseline (optional)*
+
+1. Open SEB, perform a search.
+2. DevTools → Network → =SaveSearchCriteriaToSession=.
+3. Note POST, =application/json=, body shape, Cookie header.
+
+*Step 2 — Inject via direct POST (bypass UI)*

+| =displayPriorityJourneys= | =false=                         |
+| =quickSearch=             | =""=                            |
+
+*Burp:* Repeater → replace JSON body → send.
+
+*Browser console* (on SEB page, same origin):
+
+#+begin_src javascript
+fetch('ScheduleExecutionBoard.aspx/SaveSearchCriteriaToSession', {
+  method: 'POST',
+  credentials: 'include',
+  headers: { 'Content-Type': 'application/json; charset=utf-8' },
+  body: JSON.stringify({
+    searchID: '0.X',
+    orderID: '0.X',
+    date: '"); alert(document.domain);//',
+    time: '00:00',
+    hours: 24,
+    displayPriorityJourneys: false,
+    quickSearch: ''
+  })
+}).then(r => console.log('status', r.status));
+#+end_src
+
+*curl* (replace host, path, cookies):
+
+#+begin_src bash
+curl -s -o /dev/null -w "%{http_code}" \
+  -X POST "https://<host>/<TMCWebPortal>/SEB/ScheduleExecutionBoard.aspx/SaveSearchCriteriaToSession" \
+  -H "Content-Type: application/json; charset=utf-8" \
+  -H "Cookie: <paste-session-cookies>" \
+  -d "{\"searchID\":\"0.X\",\"orderID\":\"0.X\",\"date\":\"\\\"); alert(document.domain);//\",\"time\":\"00:00\",\"hours\":24,\"displayPriorityJourneys\":false,\"quickSearch\":\"\"}"
+#+end_src
+
+*Step 3 — Trigger render (stored XSS)*
+
+1. Full navigation reload of =ScheduleExecutionBoard.aspx= (F5).
+2. =SetupControls()= embeds session =date= (~lines 1854–1855).
+
+*Step 4 — Confirm*
+
+| Check             | Before fix (expected)                                                 |
+|-------------------+-----------------------------------------------------------------------|
+| Popup / console   | =alert(document.domain)= runs                                         |
+| View Source       | Literal ="); alert(...)= inside =$('#txtStart').val("...")= unescaped |
+| Network on reload | Normal GET only; XSS from inline script                               |
+| Other users       | No effect (different session)                                         |
+
+*Step 5 — Optional:* malicious =time= or =orderID=.
+
+*Step 6 — Clean up:* log out/in or POST valid date/time.
+
+*** Comparison matrix (before vs after fixes)
+
+Run the same Steps 2–4 after each change:
+
+| Observation                      | Before fix | After encoding only | After validation only | After both    |
+|----------------------------------+------------+---------------------+-----------------------+---------------|
+| POST malicious =date= accepted?  | Yes (200)  | Yes (200)           | No / not stored       | No            |
+| =alert= on reload?               | *Yes*      | *No*                | Depends*              | *No*          |
+| Executable JS in View Source?    | *Yes*      | *No* (escaped)      | Depends*              | *No*          |
+| =#txtStart= shows attack text?   | Maybe      | Escaped/safe        | Default/empty         | Default/empty |
+| Normal UI search + reload works? | Yes        | Yes                 | Yes                   | Yes           |
+
+*If only validation: reload may show no XSS without encoding — still apply both fixes.
+
+*** Why UI-only testing misses the bug
+
+| Path                       | =DateValidation()= runs? | Payload reaches session? |
+|----------------------------+--------------------------+--------------------------|
+| Click Search in UI         | Yes                      | No (normal typing)       |
+| Direct POST / Burp / fetch | *No*                     | *Yes*                    |
+
+Reproduction *must* use direct POST to match the pentest.
+
+*** Evidence to capture (for fix sign-off)
+
+1. Request (POST body with payload).
+2. Screenshot of alert (before) or no alert (after).
+3. View Source snippet around =$('#txtStart').val(=.
+4. Regression: legitimate date, reload, criteria restored.
+
+*** Safety and scope
+
+- No production without approval.
+- Prefer =alert(document.domain)= over exfiltration demos.
+- Self-XSS: coding defect demo, not mass compromise.
+
+-----
+
+** How to fix it
+
+Use *two layers*: output encoding + server-side validation.
+
+*** Fix 1 — Output encoding (required)
+
+File: [[file:d:/_dev/WebPortal/src/code/AmberWebUI/SEB/ScheduleExecutionBoard.aspx][ScheduleExecutionBoard.aspx]], =SetupControls()= (~1847–1884).
+
+| Line (approx) | Field           | Encode |
+|---------------+-----------------+--------|
+| 1849–1850     | SessionSearchID | Yes    |
+| 1854–1855     | SessionDate     | Yes    |
+| 1860–1861     | SessionTime     | Yes    |
+| 1872–1874     | SessionOrderID  | Yes    |
+| 1878–1879     | QuickSearch     | Yes    |
+
+*Before:*
+
+#+begin_src javascript
+$('#txtStart').val("<%= SessionDate %>");
+#+end_src
+
+*After:*
+
+#+begin_src javascript
+$('#txtStart').val("<%= HttpUtility.JavaScriptStringEncode(SessionDate ?? string.Empty) %>");
+#+end_src
+
+Encode =if= guards too, or use code-behind booleans (=HasSessionDate=).
+
+*** Fix 2 — Server-side input validation
+
+File: [[file:d:/_dev/WebPortal/src/code/AmberWebUI/SEB/ScheduleExecutionBoard.aspx.cs][ScheduleExecutionBoard.aspx.cs]], =SaveSearchCriteriaToSession= (~337).
+
+| Parameter  | Validation rule                         |

+| =time=     | =^[0-2][0-9]:[0-5][0-9]$=               |
+| =orderID=  | =^[0-9]+(\.X)?$=                        |
+| =searchID= | Same as =orderID=                       |
+| =hours=    | Clamp 1–999                             |
+
+#+begin_src csharp
+[WebMethod]
+public static void SaveSearchCriteriaToSession(...)
+{
+    if (!IsValidSebDate(date) || !IsValidSebTime(time)
+        || !IsValidQueryComponentId(orderID) || !IsValidQueryComponentId(searchID))
+    {
+        return;
+    }
+    var sebState = new SEBSessionState();
+    // ...
+}
+#+end_src
+
+*Date regex:*
+
+#+begin_src
+^[0-9]{4}-(((0[13578]|(10|12))-(0[1-9]|[1-2][0-9]|3[0-1]))|(02-(0[1-9]|[1-2][0-9]))|((0[469]|11)-(0[1-9]|[1-2][0-9]|30)))$
+#+end_src
+
+*** Fix 3 — What not to do
+
+- Do not rely on client =DateValidation()= alone.
+- Do not use =HtmlEncode= in JS string literals.
+- Do not use =innerHTML=; keep =.val()=.
+
+*** Fix 4 — Verification / test plan
+
+Master procedure: *Replicating the vulnerability* section above.
+
+*Negative test:*
+
+#+begin_src json
+{
+  "searchID": "0.X",
+  "orderID": "0.X",
+  "date": "\"); alert(1);//",
+  "time": "00:00",
+  "hours": 24,
+  "displayPriorityJourneys": false,
+  "quickSearch": ""
+}
+#+end_src
+
+*Pass:* No alert; escaped in source; invalid date not stored (with Fix 2).
+
+*Positive test:* UI search + reload restores criteria.

+#+title: I Thought I Knew System Design Until I Met a Google L7 Interviewer
+#+filetags: :articles:notes:
+
+* AI summary:
+- System design is not about memorising architecture patterns; it is about knowing why each component is needed.
+- Start with real numbers first, such as traffic, read/write ratio, latency, and throughput, before drawing the design.
+- Every component, like caching, sharding, or replication, only helps under certain conditions.
+- Good designers think through failure cases, such as database crashes, cache delays, or datacentre splits.
+- The best approach is to start simple, measure the system, and only add complexity when a clear metric proves it is needed.

+Sharding is the process of splitting a database into smaller, more manageable pieces called shards. Each shard is a separate database that contains a subset of the data. Replication, on the other hand, is the process of copying data from one database to another. This can be done for backup purposes or to improve performance by distributing read requests across multiple replicas.

+This is the part that changes everything. Every component has this envelope of conditions where it actually helps. Caching works
+when reads dominate and access patterns cluster together. Sharding makes sense when write throughput matters way more than
+transactional guarantees. Replication helps when read availability beats consistency.

+| Outlet                             | Best for                                                             | How to use it                                                                                                                                   |
+| **TLDR Tech**                      | Fast daily summaries of startups, programming, AI, tools             | Probably the best “read with coffee” option. It is designed as a 5-minute daily tech newsletter. [fn:1]                                         |
+| **Hacker News**                    | What developers are discussing right now                             | Skim the top 5 posts, but don’t get dragged into every comment thread. Great for trends, new tools, and engineering debates. [fn:2]             |
+| **InfoQ**                          | Serious software engineering, architecture, DevOps, backend trends   | Better for deeper engineering updates rather than quick gossip/news. It focuses on software development trends and best practices. [fn:3]       |
+| **The Pragmatic Engineer**         | Big tech, startups, engineering culture, career insights             | Very good for understanding what is happening inside tech companies and engineering teams. [fn:4]                                               |
+| **GitHub Blog / GitHub Changelog** | Developer tooling, GitHub features, CI/CD, Copilot, security updates | Useful because changes here can directly affect your workflow. The changelog covers GitHub product updates in one place. [fn:5]                 |
+| **Stack Overflow Blog**            | Programming practice, developer surveys, AI/dev trends               | Good for broader developer ecosystem articles and opinions around programming. [fn:6]                                                           |
+| **BleepingComputer**               | Cybersecurity news you should know                                   | Worth checking briefly, especially if you work with web apps, authentication, dependencies, or infrastructure. [fn:7]                           |
+| **Ars Technica**                   | Tech policy, AI, operating systems, security, wider tech context     | More general than software-engineering-specific, but useful for understanding the bigger tech landscape. [fn:8]                                 |
+| **The Register**                   | Enterprise tech, cloud, security, software industry news             | Good if you want a slightly more blunt, IT/professional angle on tech news. [fn:9]                                                              |
+| **The Changelog**                  | Open source and developer ecosystem news                             | Better as a weekly listen/read rather than daily, but useful for open-source updates. [fn:10]                                                   |
+For your **10-minute morning routine**, I’d keep it simple:
+
+**Daily:**
+
+1. **TLDR Tech** — 5 minutes
+2. **Hacker News** — 3 minutes
+3. **BleepingComputer or GitHub Changelog** — 2 minutes
+
+**Once or twice a week:**
+Read **The Pragmatic Engineer** or **InfoQ** for something more thoughtful and career/architecture-focused.
+
+My personal pick for you would be: **TLDR Tech + Hacker News + GitHub Changelog**, then **InfoQ** when you want something more useful for uni/project/dissertation-level software engineering.
