Detailsinfo

A vulnerability classified as problematic has been found in NamelessMC Nameless up to 2.1.x. Affected is an unknown function. The manipulation with an unknown input leads to a cookie validation vulnerability. CWE is classifying the issue as CWE-565. The product relies on the existence or values of cookies when performing security-critical operations, but it does not properly ensure that the setting is valid for the associated user. This is going to have an impact on integrity. CVE summarizes:

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, an insecure view count mechanism in the forum page allows an unauthenticated attacker to artificially increase the view count. The application relies on a client-side cookie (nl-topic-[tid]) (or session variable for guests) to determine if a view should be counted. When a client does not provide the cookie, every page request increments the counter, leading to incorrect view metrics. This issue has been patched in version 2.2.0.
