Official Description
BEA WebLogic Express and Server 7.0 through 8.1 SP 1, under certain circumstances when a request to use T3 over SSL (t3s) is made to the insecure T3 port, may use a non-SSL connection for the communication, which could allow attackers to sniff sessions.
Technical Analysis
CVE-2003-1221 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.
