Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stored DOM-based XSS in CI4MS. π **Consequences**: Malicious scripts execute in victim browsers via navigation menus. Leads to session hijacking, data theft, or defacement.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-79 (XSS). π **Flaw**: User input added to navigation menus is **not sanitized**. Untrusted data is rendered directly into the DOM without escaping.
π» **Attacker Actions**: Execute arbitrary JavaScript. π΅οΈ **Impact**: Steal cookies/sessions, redirect users, or phish credentials. π **Data Risk**: High confidentiality impact (C:H) due to stored nature.
Q5Is exploitation threshold high? (Auth/Config)
π **Auth Required**: Yes (PR:L). π **Network**: Remote (AV:N). π― **UI Interaction**: None required (UI:N). β οΈ **Threshold**: Low for authenticated users. Easy to inject via admin menu features.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exploit**: No PoC provided in data. π **Wild Exploit**: Unconfirmed. However, the flaw is logical and likely easy to exploit manually if authenticated.
Q7How to self-check? (Features/Scanning)
π **Check**: Look for CI4MS versions < 0.31.0.0. π **Scan**: Test 'Menu Management' input fields for script injection. Check if `<script>` tags are stored and executed in navigation.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes. π₯ **Patch**: Upgrade to **CI4MS 0.31.0.0** or later. π **Ref**: [GitHub Release](https://github.com/ci4-cms-erp/ci4ms/releases/tag/0.31.0.0).
Q9What if no patch? (Workaround)
π‘οΈ **Workaround**: If unpatched, **disable menu management** features. π« **Input Validation**: Manually sanitize all inputs before adding to navigation. ποΈ **Monitor**: Watch for unusual script tags in menu items.
