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

Summary

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

Software Description:

- 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.
