CUPS Detection

Jeremiah Grossman · blog.jeremiahgrossman.com

CUPS listens on localhost:631 over HTTP and is not covered by Firefox port banning, so a remote page can probe for it. Grossman ties the CVE-2008-0047 CGI heap overflow to drive-by reach and gives a detection probe: an img pointing at localhost:631/images/navbar.gif whose onload and onerror handlers report whether CUPS is running.
