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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
