A hidden authentication backdoor (CVE-2026-11405) in multiple Tenda router firmware versions allows an attacker to bypass normal MD5-based auth by supplying a plaintext backdoor password stored in 'sys.rzadmin.password', granting full administrative web-panel access; CERT/CC reports no patch, advises disabling remote web management and reducing LAN exposure, and warns the flaw is likely to be targeted by botnets.
