Date: 2005-jun-29
Security risk: highly critical
Impact: system access

Vulnerability: arbitrary PHP code execution

Description

Kuba Zygmunt discovered a flaw in the input validation routines of Drupal's
filter mechanism. An attacker could execute arbitrary PHP code on a target=
=20
site when public comments or postings are allowed.
Versions affected
-----------------
Drupal 4.5.0, 4.5.1, 4.5.2, 4.5.3
Drupal 4.6.0, 4.6.1
Solution
--------
Either disable public comments and postings, or upgrade to the latest Drupal
version:
- If you cannot upgrade immediately, you can secure your site by disabling
public postings and comments. Log in as an administrator, go to
"administer >> access control" and make sure that untrusted roles don't
have the permissions to submit or edit content.
- If you are running Drupal 4.5.x, then upgrade to Drupal 4.5.4.
- If you are running Drupal 4.6.x, then upgrade to Drupal 4.6.2.
