CVE-2024-45416Network attack vector

Root code execution via unvalidated session scripts

Published Sep 16, 2024 · Updated Sep 18, 2024

Code execution in ZTE ZXHN router firmware allows remote attackers to run attacker-supplied Lua files as root through HTTPD. The session_init function executes every file in /var/lua_session with Lua dofile without checking that the file is a valid session script. Exploitation requires a path to write a malicious file into that directory; successful execution grants root-level control of the router.
