backuppc vulnerabilites
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS
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 backup browser 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. This issue did not affect
Ubuntu 11.10. (CVE-2011-3361)
