Medium Nessus Plugin ID 56664
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt 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)
