CVSS v3.1
Official Description
Cisco Media Processing Software before 1.2 on Media Experience Engine (MXE) 5600 devices has a default root password, which makes it easier for context-dependent attackers to obtain access via (1) the local console, (2) an SSH session, or (3) a TELNET session, aka Bug ID CSCto77737.
Technical Analysis
CVE-2011-1623 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.
