An input validation error exists in the cgi_puts function in cgi-bin/template.c in the template engine in CUPS before 2.0.3 when processing QUERY parameter to help/. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
