Official Description
The ClientTrust program in Novell BorderManager does not properly verify the origin of authentication requests, which could allow remote attackers to impersonate another user by replaying the authentication requests and responses from port 3024 of the victim's machine.
Technical Analysis
CVE-2000-0651 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.
