CVE-2023-39224

Authenticated adjacent-network OS command execution

Published Sep 6, 2023 · Updated Sep 26, 2024

OS command injection in affected TP-Link Archer C5 and C7 firmware allows remote authenticated users to execute arbitrary commands. JPCERT/CC and TP-Link have not published the affected function, request parameter, or operation that passes untrusted input to an OS command interpreter. All Archer C5 firmware and Archer C7 firmware before Archer C7(JP)_V2_230602 are exposed to logged-in users on an adjacent network.
