CWE-119Published: December 31, 2002· Updated: Jun 16, 2026
Official Description
Buffer overflow in the httpdProcessRequest function in LibHTTPD 1.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP POST request.
Technical Analysis
CVE-2002-2400 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2002-2400. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
