Srvcheck is a proof of concept for the MS06-011 (http://www.microsoft.com/technet/security/Bulletin/MS06-011.mspx). This tool scans your network for weak service DACLs and enumerates vulnerable services.
Due to the fact that those permissive dacls allows remote authenticate users to modify the command that is executed, srvcheck deploys an vbs payload that will execute a bindshell.

At this time, several products are affected for this vulnerability so once you get a valid domain user, srvcheck allows you to get access into several systems.


Details

The public version, srvcheck2 was improved. The new payload deployed with srvcheck3 works tranfering files by ftp, and allows faster network scanning.

Usage Information:
Srvcheck 3 - Windows Services ACL permission Scanner
