"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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
