Description

BackupPC contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'share' parameter upon submission to the index.cgi script before returning it in the RestoreFile.pm script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
