CVE-2004-2761
CWE-310Published: January 5, 2009· Updated: Jun 16, 2026
Official Description
The MD5 Message-Digest Algorithm is not collision resistant, which makes it easier for context-dependent attackers to conduct spoofing attacks, as demonstrated by attacks on the use of MD5 in the signature algorithm of an X.509 certificate.
Technical Analysis
CVE-2004-2761 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
A proof-of-concept (PoC) exploit exists for CVE-2004-2761. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
