SOL15578: MD5 Message-Digest Algorithm vulnerability CVE-2004-2761

Security AdvisorySecurity Advisory

Original Publication Date: 09/11/2014


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. (CVE-2004-2761)


A context-dependent attacker may be able to conduct spoofing attacks.

Recommended Action

If the previous table lists a version in the Versions known to be not 
vulnerable column, you can eliminate this vulnerability by upgrading to the 
listed version. If the table does not list any version in the column, then no
upgrade candidate currently exists.

To mitigate this vulnerability, you can limit access for the ARX GUI to only 
use secure networks.
