- This module exploits a SQL injection flaw in the Lyris ListManager
- software for Microsoft SQL Server. This flaw allows for arbitrary commands
- to be executed with administrative privileges by calling the xp_cmdshell
- stored procedure. Additionally, a window of opportunity is opened during the
- ListManager for MSDE install process; the 'sa' account is set to the password 'lminstall'
- for a 5-10 minute period. After the installer finishes, the password is
- permanently set to 'lyris' followed by the process ID of the installer (a 1-5 digit number).
