Alex Korobkin discovered that the CUPS web interface incorrectly protected
against cross-site scripting (XSS) attacks. If an authenticated user were
tricked into visiting a malicious website while logged into CUPS, a remote
attacker could modify the CUPS configuration and possibly steal
confidential data.
