CVE-2013-0133
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUntrusted search path vulnerability in /usr/local/psa/admin/sbin/wrapper in Parallels Plesk Panel 11.0.9 allows local users to gain privileges via a crafted PATH environment variable.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceLocal privilege escalation vulnerability in Parallels Plesk Panel 11.0.9's admin wrapper script (/usr/local/psa/admin/sbin/wrapper) due to an untrusted search path. A local attacker can manipulate the PATH environment variable to inject malicious executables that the wrapper will execute with elevated (root) privileges, bypassing authentication controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Plesk Panel installationRun: dpkg -l | grep -i plesk or rpm -qa | grep -i pleskAffected if Plesk Panel is not installed on the system
-
Verify exact version is 11.0.9Run: /usr/local/psa/admin/bin/sw-engine-pleskrun --version or check /usr/local/psa/version fileAffected if Version returned is exactly 11.0.9
-
Check if vulnerable wrapper existsRun: ls -la /usr/local/psa/admin/sbin/wrapperAffected if The wrapper file exists at this path
-
Inspect wrapper for PATH dependencyRead the wrapper script content: cat /usr/local/psa/admin/sbin/wrapper and look for commands invoked without absolute paths (e.g., without leading /)Affected if The script uses relative commands or does not sanitize the PATH environment variable before executing binaries
-
Check wrapper permissionsRun: ls -la /usr/local/psa/admin/sbin/wrapper and verify ownership and permissionsAffected if The file is owned by root and has setuid/setgid bits, or is executable by privileged users
If Plesk Panel version 11.0.9 is installed and the wrapper script at /usr/local/psa/admin/sbin/wrapper exists and uses untrusted search paths, the system is vulnerable to local privilege escalation via PATH manipulation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict the PATH environment variable to trusted system directories only (e.g., /usr/local/bin:/usr/bin:/bin) before executing Plesk utilities, or upgrade to a patched version of Plesk Panel that uses absolute paths or sanitizes the PATH variable.
