Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: XWiki Platform allows arbitrary Remote Code Execution (RCE) via user profiles.β¦
π‘οΈ **Root Cause**: **CWE-95** (Improper Neutralization of Code). <br>π **Flaw**: The system fails to properly sanitize user input when adding instances to user profiles or pages, allowing malicious code injection.
Q3Who is affected? (Versions/Components)
π¦ **Affected Versions**: <br>β’ 9.2-rc-1 to 14.10.21 <br>β’ 15.0-rc-1 to 15.5.5 <br>β’ 15.6-rc-1 to 15.10.2 <br>β οΈ **Product**: XWiki Platform (Open Source Wiki).
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: <br>β’ Execute **Arbitrary Remote Code**. <br>β’ Gain **High Privileges** (CVSS A:H, I:H, C:H). <br>β’ Access sensitive data and modify system integrity.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: <br>β’ **Auth Required**: Yes (PR:L). <br>β’ **Condition**: User must have **Edit Permissions**. <br>β’ **UI Required**: No (UI:N). <br>π **Difficulty**: Low for authenticated editors.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exploit**: <br>β’ **PoC Status**: No specific PoC listed in data (pocs: []). <br>β’ **Wild Exploitation**: Likely low initially, but RCE risks are high once authenticated.β¦
π **Self-Check**: <br>1. Identify XWiki version. <br>2. Check if version falls in affected ranges. <br>3. Review user permissions for 'Edit' access. <br>4. Scan for code injection in user profiles.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Official Fix**: <br>β’ **Status**: Fixed via GitHub commits (e.g., 742cd45, bbde8a4). <br>β’ **Action**: Upgrade to versions **14.10.21+**, **15.5.5+**, or **15.10.2+**.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: <br>β’ **Restrict Permissions**: Remove 'Edit' rights for untrusted users. <br>β’ **Input Validation**: Manually sanitize user profile fields.β¦
β‘ **Urgency**: **HIGH**. <br>β’ **CVSS Score**: High (9.8+ implied by vector). <br>β’ **Priority**: Immediate patching recommended for all affected versions. RCE is critical.
