A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 13.10
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS

CUPS could be made to expose sensitive information over the network.

Software Description

  • cups - Common UNIX Printing System™


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.
