CVE-2023-39780 is an authenticated OS command injection vulnerability affecting ASUS RT-AX55 routers running firmware 3.0.0.4.386.51598. Crafted input to the qos_bw_rulelist parameter of the router’s web configuration interface allows execution of arbitrary operating-system commands. Exploitation has been observed in ASUS router compromise campaigns, including AyySSHush, where attackers combine authentication weaknesses with command execution to modify router configuration and establish persistent SSH access. Campaign accounts also describe injection through an OAuth refresh-token parameter; its precise relationship to the qos_bw_rulelist injection mechanism is not established.

A specific CVE for which exploit code is implemented in native C inside TuxBot, but the exploit engine is dead code and never called at runtime in the analyzed version.
A command injection vulnerability associated with the compromise of ASUS WRT routers in Operation WrtHug, a suspected China-nexus espionage infrastructure campaign. Compromised routers serve as Operational Relay Boxes that relay traffic and conceal attacker activity. Patches are available, but outdated and end-of-life devices remain exposed.
Unknown (vulnerability exploited by the AyySSHush/ViciousTrap botnet; mentioned as a shared/overlapping vulnerability with the WrtHug cluster).
Major command injection vulnerability in ASUS WRT routers, reported as used in both Operation WrtHug and the earlier AyySSHush campaign.
