- Advisory ID: DRUPAL-SA-CONTRIB-2013-004
- Project: Live CSS (third-party module)
- Version: 6.x, 7.x
- Date: 2012-January-16
- Security risk: Highly critical
- Exploitable from: Remote
- Vulnerability: Arbitrary PHP code execution
Description
This module enables you to save CSS and LESS files on the server via your browser.
The module doesn't check that the file being saved isn't a script or executable.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer CSS".
