Privilege escalation in Lxcenter Kloxo
CVE-2012-10022
Kloxo versions 6.1.12 and earlier contain two setuid root binaries—lxsuexec and lxrestart—that allow local privilege escalation from uid 48. The lxsuexec binary performs a uid check and permits execution of arbitrary commands as root if the invoking user matches uid 48. This flaw enables attackers with Apache-level access to escalate privileges to root without authentication.
