CVE-2024-37626Public exploit

Command execution via unsanitized iface parameter

Published Jun 20, 2024 · Updated Jul 9, 2026

OS command injection in TOTOLINK A6000R firmware 1.0.1-B20201211.2000 allows remote attackers to execute commands through iface. The vif_enable route in /usr/lib/lua/luci/controller/mtkwifi.lua fails to neutralize shell metacharacters in the iface path value before command execution. Reachability is limited to the router management interface on the adjacent network; the public proof of concept includes a sysauth cookie even though CISA scores privileges as none.
