Description

This module exploits an anonymous remote code execution vulnerability on D-Link DIR-605L routers. The vulnerability exists while handling user supplied captcha information, and is due to the insecure usage of sprintf on the getAuthCode() function. This module has been tested successfully on D-Link DIR-605L firmware 1.13 (emulated) and firmware 1.12 (real).

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.
