CVE-2012-10022: Kloxo <= 6.1.12 Local Privilege Escalation

• Severity: high (CVSS 8.5 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-08-01 · updated 2026-06-16
• Weakness: CWE-269

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.

Affected products

• LXCenter Kloxo: through 6.1.12
