Description

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.

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.
