CVE-2006-0805: High severity Francisco Burzi PHP-Nuke vulnerability
The CAPTCHA functionality in php-Nuke 6.0 through 7.9 uses fixed challenge/response pairs that only vary once per day based on the User Agent (HTTPUSERAGENT), which allows remote attackers to bypass CAPTCHA controls by fixing the User Agent, performing a valid challenge/response, then replaying that pair in the randomnum and gfxcheck parameters.
