CVE-2011-1176

CVE-2011-1176 describes a privilege escalation vulnerability in the mpm-itk Multi-Processing Module (versions 2.2.11-01 and 2.2.11-02) for the Apache HTTP Server. The flaw lies in the configuration merger's improper handling of sections specifying NiceValue without AssignUserID, potentially allowing remote attackers to gain privileges by leveraging root user and group IDs of an mpm-itk process. This vulnerability has a CVSS score of 4.3 (Medium), indicating a network-based attack with medium complexity, requiring no authentication, and resulting in partial integrity impact. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting a low current threat level.
