The proc_deutf function in includes/functions_vbseocp_abstract.php in vBSEO 3.5.0, 3.5.1, 3.5.2, 3.6.0, and earlier allows remote attackers to insert and execute arbitrary PHP code via "complex curly syntax" in the char_repl parameter, which is inserted into a regular expression that is processed by the preg_replace function with the eval switch.

Security readout for executives and security teams

CVE-2012-5223 affects legacy vBSEO versions used with vBulletin. A remote attacker could make the software execute attacker-supplied PHP code, potentially taking over the website account or server context. The bundle includes public exploit references and a vendor patch bulletin, but no evidence of active exploitation. Exposure is likely limited to legacy vBulletin sites still running vBSEO 3.6.0 or earlier. Internet-facing forum installations are the main concern. The source bundle does not provide CPEs, deployment prevalence, or currently supported version details. Treat confirmed exposed installations as a priority incident-prevention task. The vulnerability is old, public, and severe, but active exploitation is not evidenced in the supplied sources. Business urgency depends on whether legacy vBSEO remains deployed on public forums. Mitigation focus: Identify all vBulletin sites using vBSEO and record installed versions.; Apply the vendor patch bulletin for supported vBSEO versions.; Remove or disable vBSEO where patched support cannot be confirmed..
