Overview<\/strong><\/p>\n

This report details a high-severity vulnerability in NamelessMC, a widely-used website software for Minecraft servers. This vulnerability (CVE-2025-29784) affects versions 2.1.4 and prior, and if exploited, can lead to performance degradation and potential system compromise or data leakage. This vulnerability matters because of the widespread use of NamelessMC and the potential for attackers to exploit it, causing significant disruption.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-29784
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: System performance degradation, potential denial-of-service attacks, system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

NamelessMC | 2.1.4 and prior<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from the lack of length validation for the ‘s’ parameter in GET requests for the forum search functionality in NamelessMC. Attackers can exploit this oversight by submitting excessively long search queries, which can degrade system performance and potentially lead to denial-of-service (DoS) attacks.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how this vulnerability might be exploited. In this case, an attacker sends a GET request with an excessively long ‘s’ parameter to the search endpoint.<\/p>\n

GET \/forum\/search?s=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA... HTTP\/1.1\nHost: vulnerable-server.com<\/code><\/pre>\n
Note: The ‘A’s in the ‘s’ parameter represent the excessively long search query. The actual query would be much longer to cause noticeable performance degradation or a DoS attack.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users of NamelessMC version 2.1.4 and prior are advised to update to version 2.2.0 where this issue has been patched. If an immediate update is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
