Title: VBulletin Profile.PHP Email Field HTML Injection Vulnerability

Severity: MODERATE

Description:


vBulletin is a commercially available web-based bulletin-board application. It is implemented in PHP and may be run on UNIX and variants as well as Microsoft Windows.

vBulletin is prone to an HTML-injection vulnerability. The application fails to properly sanitize user-supplied input to the 'email' field of the 'profile.php' script.


Attacker-supplied HTML and script code would be executed in the context of the affected website, potentially allowing for the theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.

This issue is reported to affect vBulletin versions 3.0.12 through 3.5.3. Other versions may also be affected.

Affected Products:

  • VBulletin VBulletin 3.0.12
  • VBulletin VBulletin 3.5.1
  • VBulletin VBulletin 3.5.2
  • VBulletin VBulletin 3.5.3
