Title: e107 Website System HTML Injection Vulnerability

Severity: MODERATE

Description:

e107 Website System is a web based content management system implemented in PHP.

The e107 Website System is prone to an HTML injection vulnerability. This issue is exposed through the class2.php script. An attacker may exploit this issue by including hostile HTML and script code in form fields that support custom tags. This includes areas of the site such as Chatbox and Forum. This code may be rendered in the web browser of a user who views these areas of the site. This would occur in the security context of the site hosting e107.

The attacker-supplied HTML and script code would be able to access properties of the site, potentially allowing for theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user.

Affected Products:

  • e107.org e107 website system 0.554.0
