Publication date

27 October 2011

Releases

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 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)

Jamie Strandboge discovered that BackupPC did not properly sanitize its
input when processing log file viewer error messages, resulting in
cross-site scripting (XSS) vulnerabilities.
