Details.
A vulnerability has been discovered in the Collaborative Passwords Manager (cPassMan) web application that can be exploited to retrieve files from the local host file system. The input passed to the component “sources/downloadfile.php” via the “path” variable allows the retrieval of any file on the local file system that the web server has access to. There is no data validation or authorisation mechanisms present within this component.
