USN-1444-1: BackupPC vulnerability

Publication date

17 May 2012

Overview

BackupPC could be made to expose sensitive information over the network.


Packages

  • backuppc - high-performance, enterprise-grade system for backing up PCs

Details

It was discovered that BackupPC did not properly sanitize its input when
processing RestoreFile error messages, resulting in a cross-site
scripting (XSS) vulnerability. With cross-site scripting vulnerabilities,
if a user were tricked into viewing server output during a crafted server
request, a remote attacker could exploit this to modify the contents, or
steal confidential data, within the same domain.
