Severity: Medium
Vulnerability Published: 2005-12-08
Patch Published: N/A
CVE [?]: CVE-2005-4145
CPE [?]: N/A

Synopsis

The remote database server uses a weak password for one of its administrative accounts.

Description

The remote host appears to be running ListManager, a web-based commercial mailing list management application from Lyris.

The version of ListManager on the remote host was installed using Microsoft SQL Server Desktop Engine (MSDE) for its database backend along with a weak password for the 'sa' account - 'lyris' followed by up to 5 digits. An attacker may be able to discover this password by means of a brute-force attack and gain administrative access to the database.

Solution

Assign a strong 'sa' password to MSDE and update the setting for '$sql_password' in ListManager's 'lmcfg.txt' file.
