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 · unedited
The loadModule function in lib/WebGUI/Asset.pm in WebGUI before 7.5.30 (stable) allows remote attackers to execute arbitrary code by uploading a Perl module and accessing it via a crafted URL.

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
How this class of weakness works · CWE-94

The application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Upgrade available Upgrade to a release after 7.5.10
Recommended fix High confidence

WebGUI 7.5.30 (stable) or later

  1. 1. Back up the current WebGUI installation and database before attempting any upgrade
  2. 2. Download WebGUI version 7.5.30 or later (stable release) from the official WebGUI repository
  3. 3. Replace the existing WebGUI files with the new version, preserving custom configuration files
  4. 4. Run any provided upgrade scripts or database migration tools included with the new version
  5. 5. Verify the loadModule function in lib/WebGUI/Asset.pm has been updated
  6. 6. Test that the code injection vector is no longer exploitable
  7. 7. Restart the WebGUI service
Caveat Review release notes between your current version and 7.5.30 for any configuration or compatibility changes; test thoroughly in a staging environment before production deployment
