Description
GRR is a resource management and reservation application. Prior to the advisory-reported fixed version 4.5.0, the database restoration feature fails to enforce or validate file paths. A user with administrator privileges can manipulate the input to read or delete arbitrary files on the server, causing sensitive file disclosure and denial of service through file deletion. The impact is amplified when the server runs with elevated privileges. The advisory reports this issue as fixed in version 4.5.0.
