Title: PowerScripts PlusMail WebConsole Poor Authentication Vulnerability
Severity: HIGH
Description:
PowerScripts PlusMail Web Control Panel is a web-based administration suite for maintaining mailing lists, mail aliases, and web sites. It is reportedly possible to change the administrative username and password without knowing the current one, by passing the proper arguments to the script. After this has been accomplished, the web console allows a range of potentially destructive activities including changing of e-mail aliases, mailing lists, web site editing, and various other privileged tasks.
This can be accomplished by submitting a login request with an additional "new_login" argument (with the value "reset password") to the plusmail script. The username and password will be changed to those provided as the arguments "username," "password," and "password1". The two password fields contain the same password and are simply used to ensure the two match. (Other exploits have used the argument "login" for the username, and have submitted arbitrary strings to the "new_login" argument.)
The specific affected versions have not been determined, and the developer cannot be located.
Affected Products:
- PowerScripts PlusMail WebConsole 1.0.0
