CVE-2023-27837Network attack vector

Unauthenticated command execution via unneutralized key parameter

Published Jun 13, 2023 · Updated Jan 3, 2025

Command injection in TP-Link TL-WPA8630P (US) V2 firmware 171011 allows remote attackers to execute commands via a crafted key parameter. The sub_40A774 function incorporates the key parameter into a command without neutralizing command delimiters before execution. Network access without authentication is sufficient, and injected commands can read or alter device data or interrupt service.
