Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Remote PHP Code Injection in PmWiki's `PageListSort()` function. π₯ **Consequences**: Attackers can inject/execute arbitrary PHP code.β¦
π οΈ **Root Cause**: Improper input validation in the `PageListSort()` function. β οΈ **Flaw**: Allows untrusted data to be processed as executable PHP code, bypassing security controls.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: PmWiki (Open-source Wiki tool). π **Versions**: 2.0.0 through 2.2.34. β οΈ **Note**: Other versions may also be vulnerable.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Hackers Can**: Execute arbitrary PHP code. π **Privileges**: Run code within the application context. πΎ **Impact**: Manipulate the app, control the underlying OS, or cause other severe attacks.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: LOW. π **Auth**: Remote exploitation (no authentication required mentioned). βοΈ **Config**: Directly targets the `PageListSort()` function, likely accessible via standard Wiki interactions.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exp?**: YES. π **Sources**: Exploit-DB IDs 18243 and 18149 are available. π **Status**: Wild exploitation is possible given public PoCs.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for PmWiki installations. π **Version**: Verify if version is between 2.0.0 and 2.2.34. π§ͺ **Test**: Check if `PageListSort()` parameters are vulnerable to PHP injection payloads.
Q8Is it fixed officially? (Patch/Mitigation)
π‘οΈ **Official Fix**: Refer to PmWiki PITS #01271 for confirmation. π **Action**: Update to a patched version immediately if available. π **Ref**: http://www.pmwiki.org/wiki/PITS/01271
Q9What if no patch? (Workaround)
π§ **No Patch?**: Implement strict input filtering on `PageListSort()` parameters. π« **Mitigation**: Disable or restrict access to the vulnerable function if possible.β¦
π₯ **Urgency**: CRITICAL. π¨ **Priority**: HIGH. β‘ **Reason**: Remote Code Execution (RCE) with public exploits. Immediate patching or mitigation is essential to prevent system takeover.
