Drupal AHAH elements cross-site request forgery
| drupal-ahah-csrf (44453) |  Medium Risk |
Description:
Drupal is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input. By persuading a victim to visit a specially-crafted Web site, a remote attacker could send a malformed HTTP request to cause the victim to submit cached forms or forms containing AHAH elements, upload files, and perform other arbitrary tasks. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.
