CVE-2012-10022: Kloxo <= 6.1.12 Local Privilege Escalation
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.
Security readout for executives and security teams
Plain-English summary
This is a legacy Kloxo hosting-control-panel flaw where Apache-level access could become root on the server. The business risk is full host compromise for exposed or multi-tenant systems still running Kloxo 6.1.12 or earlier. The source bundle does not show active exploitation, but public exploit references exist.
Executive priority
Treat as urgent for any internet-facing or multi-tenant legacy hosting server. Root compromise can expose hosted sites, credentials, and customer data. If Kloxo is not present, this should be closed as not applicable.
Technical view
Kloxo 6.1.12 and earlier reportedly include setuid root binaries lxsuexec and lxrestart. lxsuexec checks for uid 48 and can execute commands with root privileges when invoked by that user. CVSS 4.0 is 8.5, with local attack vector, low complexity, low privileges, no user interaction, and high vulnerable-system impact.
Likely exposure
Exposure is most likely on old Linux hosting servers running Kloxo 6.1.12 or earlier, especially where Apache or web applications run as uid 48. This is not described as unauthenticated remote exploitation; the attacker needs local or Apache-level execution first.
Exploitation context
The CVE is not in KEV and the bundle gives no evidence of active exploitation. However, multiple public exploit or technical references are cited, so organizations should assume capable attackers can understand the issue if they already gain web-server-level access.
Researcher notes
The bundle’s narrative names Kloxo <= 6.1.12, but the structured affected field appears incomplete or inconsistent. Do not broaden affected versions without vendor evidence. Focus validation on installed version, setuid binaries, and whether uid 48 can invoke them.
Mitigation direction
Inventory all Kloxo installations and prioritize versions 6.1.12 and earlier.
Check current vendor or project guidance before changing binaries or permissions.
Retire or isolate legacy Kloxo hosts if no supported fix is available.
Restrict untrusted local users and web applications on affected servers.
Harden web applications to reduce paths to Apache-level execution.
Validation and detection
Confirm whether Kloxo is installed and record its exact version.
Check whether lxsuexec and lxrestart exist with setuid root permissions.
Verify whether Apache or related web processes run as uid 48.
Review affected hosts for unauthorized local users or web-level execution.
Document any compensating controls and remaining exposure.

CWE-269: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references privilege impact, so privilege escalation and authorization behavior review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Improper Privilege Management
Improper Privilege Management represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
