Official Description
Messenger Agents (nmma.exe) in Novell GroupWise 2.0.2 and 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted HTTP POST request to TCP port 8300 with a modified val parameter, which triggers a null dereference related to "zero-size strings in blowfish routines."
Technical Analysis
CVE-2006-4511 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.
