Title: Macromedia Dreamweaver MX PHP User Authentication Suite Cross-Site-Scripting Vulnerability
Severity: MODERATE
Description:
Macromedia's Dreamweaver MX is a product designed to allow visual creation of websites and web applications.
It is possible to create an authentication or access control page, using Dreamweaver MX PHP Authentication Suite. This script will generate an error page that contains dynamic content when a user fails to authenticate correctly to the site.
A cross-site-scripting vulnerability has been reported to affect PHP authentication functions used in PHP access control pages created with the Macromedia Dreamweaver MX PHP Authentication Suite.
The issue presents itself, due to a lack of sufficient sanitization performed on URI parameters that may be influenced by an attacker. An attacker may supply encoded HTML as a value for the access denied variable that is used by the affected sites' authentication page. The attacker may present this code contained in a link to an affected site, to an unsuspecting user. The malicious HTML code will be incorporated into an error page and rendered in the browser of the user if the link is followed.
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.
It should be noted that while this vulnerability has been reported to affect Macromedia Dreamweaver MX version 6, other versions might also be affected.
Affected Products:
- Macromedia Dreamweaver MX 6.0.0
