TeamViewer Vulnerability Lets Attackers Take Full Control of PCs

There are over one billion devices with TeamViewer, a software that allows users to conduct online meetings, desktop sharing, remote control, file transfer, etc. between computers. So when there is a vulnerability in such a widely used program, it becomes a big thing.

Recently, a GitHub user going by the online handle of “Gellin” discovered a critical vulnerability in TeamViewer that allows an attacker or client to remotely take over a computer without consent or knowledge of its owner.

According to proof-of-concept (PoC) published on GitHub, “an injectable C++ dll, which uses naked inline hooking and direct memory modification to change your TeamViewer permissions.” That means victim remains uninformed once TeamViewer permissions are modified.
