CVE-2016-7955 is a critical authentication bypass vulnerability affecting AlienVault OSSIM before version 5.3.1 and USM before 5.3.1. An unauthenticated remote attacker can exploit a flaw in the logcheck function by manipulating the HTTP User-Agent header, specifically "AV Report Scheduler". This allows for complete compromise, including sensitive information disclosure, application modification, or arbitrary code execution as root. With a CVSS score of 9.8 (CRITICAL), this vulnerability is easily exploitable over the network with no user interaction required, leading to high impact on confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, publicly available exploit code, or significant community discussion.
