Adn · Adn Forum · CVE-2008-6001
**Name of the Vulnerable Software and Affected Versions**
ADN Forum versions 1.0b and earlier
**Description**
The issue allows remote attackers to bypass authentication and gain sysop access. This is achieved by composing a `fpusuario` cookie with a specific string format, including an initial 'sysop:' string, an arbitrary `password` field, and a final ':sysop:0' string.
**Recommendations**
For ADN Forum versions 1.0b and earlier, as a temporary workaround, consider restricting access to the authentication mechanism until a patch is available. Avoid using the `fpusuario` cookie in a way that could allow unauthorized access. At the moment, there is no information about a newer version that contains a fix for this issue.
