Two zero-day vulnerabilities were being used by two different groups to infiltrate DrayTek Vigor enterprise routers and switch devices, enabling the attackers to access traffic and install backdoors.

The invasive action was noticed first on Dec. 4, 2019 by Netlab 360 researchers affecting the Vigor2960 v1.5.1, Vigor300B v1.5.1 and Vigor3900 v1.5.1 routers along with the VigorSwitch20P2121 v2.3.2, VigorSwitch20G1280 v2.3.2, VigorSwitch20P1280 v2.3.2, VigorSwitch20G2280 v2.3.2 and VigorSwitch20P2280 v2.3.2.

"With the help of 360 Firmware Total system, we are able to perform vulnerability research. The two 0-day vulnerability command injection points are keyPath and rtick, located in the /www/cgi-bin/mainfunction.cgi, and the corresponding Web Server program is /usr/sbin/lighttpd," Netlab said.
