Drupal UTF-8 cross-site scripting
| drupal-utf8-xss (39619) |  Medium Risk |
Description:
Drupal is vulnerable to cross-site scripting, caused by an error in the text filtering functionality. A remote attacker could exploit this vulnerability and bypass the text filter using invalid UTF-8 sequences to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the data is viewed using Internet Explorer 6. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
Platforms Affected:

- Drupal, Drupal 5.x prior to 5.6
