CVE-2007-5416
Drupal < 5.2 - Remote Code Execution via Callback Parameter Hash Collision
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2007-5416. PoCs published by ShAnKaR.
AI-analyzed exploit summary This exploit leverages a PHP Zend Hash vulnerability in Drupal <= 5.2 to execute arbitrary PHP code via crafted URL parameters, specifically targeting the `drupal_eval` callback.
Description
Drupal 5.2 and earlier does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary PHP code by invoking the drupal_eval function through a callback parameter to the default URI, as demonstrated by the _menu[callbacks][1][callback] parameter. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in Drupal.
