CVE-2024-5035Public exploit

Elevated command execution via rftest shell metacharacters

Published May 27, 2024 · Updated Aug 1, 2024

Command injection in TP-Link Archer C5400X 1_1.1.6 and earlier allows remote attackers to execute commands with elevated privileges. The boot-launched rftest listener passes socket bytes beginning with wl or nvram get to popen(), while shell metacharacters bypass its command-prefix filter. The listener is reachable from the LAN without authentication, although TP-Link disputes a practical kill chain and classifies the issue as a source-code weakness.
