Authenticated OS command execution via iface injection
Published Jul 22, 2024 · Updated Aug 2, 2024
Command injection in TOTOLINK A6000R firmware 1.0.1-B20201211.2000 allows remote authenticated users to execute OS commands via iface. The vif_disable route in /usr/lib/lua/luci/controller/mtkwifi.lua accepts command separators in its iface path argument and incorporates the value into command execution. Exploitation requires an adjacent-network administrative session, and injected command output appears in the HTTP response.
