Description

This module exploits a stack-based buffer overflow in the Solaris PAM library's username parsing code, as used by the SunSSH daemon when the keyboard-interactive authentication method is specified. Tested against SunSSH 1.1.5 on Solaris 10u11 1/13 (x86) in VirtualBox, VMware Fusion, and VMware Player. Bare metal untested. Your addresses may vary.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
