CVE-2012-3513
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 · uneditedmunin-cgi-graph in Munin before 2.0.6, when running as a CGI module under Apache, allows remote attackers to load new configurations and create files in arbitrary directories via the logdir command.
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 analysisA legacy NVD category covering weaknesses where permissions or privileges are assigned, checked, or dropped incorrectly, so an action ends up running with more access than it should. It is an umbrella label from older records, not a single flaw. The remedy depends on the specific case, but the throughline is least privilege with explicit, checked transitions wherever privilege changes.

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.
dbcve · scopedMunin 2.0.6 or latest stable 2.x release
- 1. Check the currently installed Munin version: munin-cgi-graph --version or check package manager
- 2. Upgrade Munin to version 2.0.6 or later (preferably the latest stable 2.x release)
- 3. For package-based installations: apt-get update && apt-get install munin (Debian/Ubuntu) or yum update munin (RHEL/CentOS)
- 4. If using source installation, download and install from munin-monitoring.org
- 5. After upgrade, restart Apache to ensure the new CGI module is loaded: systemctl restart apache2 or systemctl restart httpd
- 6. Verify the fix by checking that the logdir parameter is now properly sanitized and cannot be used for directory traversal
