Description

The AnyDesk GUI is vulnerable to a remotely exploitable format string vulnerability. By sending a specially crafted discovery packet, an attacker can corrupt the frontend process when it loads or refreshes. While the discovery service is always running, the GUI frontend must be started to trigger the vulnerability. On successful exploitation, code is executed within the context of the user who started the AnyDesk GUI.

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.
