Title: Alcatel OmniPCX Password File Encrypted Password Access Vulnerability
Severity: MODERATE
Description:
OmniPCX is an enterprise-level Personal Communications Exchange (PCX) system maintained and distributed by Alcatel.
A problem with some models may make it possible for remote users to gain unauthorized privileges on vulnerable systems. The problem is in the lack of shadowed passwords.
By default, OmniPCX does not use shadowed passwords. While this is not inherently a vulnerability as OmniPCX systems are not designed for multi-user access, this problem can lead to issues such as local privilege access and elevation when combined with issues such as Bugtraq ID 4127, "Alcatel OmniPCX Default Passwords Vulnerability." If a remote user is able to gain access to the system via some unprivileged account, it is possible for the user to retrieve the encrypted password hashes and launch a brute force crack attack against them offline. This may be a Chorus OS problem, currently maintained by Sun Microsystems.
This problem could allow a remote user to gain elevated privileges, and could potentially lead to local administrative access.
