Description:
Janek Vind "waraxe" has reported a weakness in PHP-Nuke, which can be exploited by malicious people to bypass certain security restrictions.

A design error in the CAPTCHA security feature, which relies only on the "sitekey", the User-Agent HTTP header, a random number, and the current date to generate the response code can be exploited to bypass the security feature by replaying any random number and response code pair for the current day.

The weakness has been reported in versions 6.0 through 7.9.
