CVE-2011-1784 describes a privilege escalation vulnerability in Keepalived versions 1.2.2 and earlier. The vulnerability stems from the pidfile_write function using insecure 0666 permissions for its PID files (keepalived.pid, checkers.pid, vrrp.pid) located in /var/run/. This allows a local attacker to overwrite these PID files, potentially enabling them to terminate arbitrary processes. The CVSS score of 3.6 indicates low severity, with a local attack vector and low complexity, primarily impacting integrity and availability. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this decade-old vulnerability.
