Overview
The vulnerability (CVE-2015-7808) affects vBulletin 5 Connect versions 5.1.2 through 5.1.9. The vulnerability exists in the vBApiHook::decodeArguments method, which allows remote attackers to conduct PHP object injection attacks and execute arbitrary PHP code via a crafted serialized object in the arguments parameter to ajax/api/hook/decodeArguments (NVD).
Technical details
