๐จ **Essence**: SQL Injection in vBulletin's `forumrunner` module. ๐ **Consequences**: Attackers can execute arbitrary SQL commands, leading to potential data theft or system compromise.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: Improper input validation in `forumrunner/includes/moderation.php`. ๐ฅ **Flaw**: The `postids` parameter in `forumrunner/request.php` is not sanitized, allowing SQL injection.
๐ **Capabilities**: Execute arbitrary SQL queries. ๐ **Impact**: Access sensitive database information, potentially compromising user data or site integrity.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **LOW**. ๐ **Auth**: Remote exploitation possible. โ๏ธ **Config**: No authentication required to send the malicious `postids` parameter.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฅ **Exploit**: **YES**. ๐ **PoC**: Available via Nuclei templates (ProjectDiscovery) and tools like `vbully`. ๐ **Wild Exploitation**: Publicly documented.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for vBulletin versions < 4.2.3 PL1. ๐ก **Feature**: Look for the `forumrunner/request.php` endpoint accepting `postids`. ๐ ๏ธ **Tool**: Use Nuclei templates for automated detection.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: **YES**. ๐ฉน **Patch**: Update to vBulletin **4.2.2 PL5** or **4.2.3 PL1** or later. ๐ **Date**: Patched around Aug 2016.
Q9What if no patch? (Workaround)
๐ง **Workaround**: If patching is impossible, **disable the `forumrunner` addon** immediately. ๐ซ **Block**: Restrict access to `forumrunner/request.php` via WAF rules if possible.
Q10Is it urgent? (Priority Suggestion)
โ ๏ธ **Priority**: **HIGH**. ๐จ **Urgency**: Critical SQLi with remote exploit code available. ๐ **Action**: Patch immediately or disable the vulnerable module to prevent data breaches.
