CVE-2023-26800Network attack vector

Unauthenticated command execution via params.path injection

Published Mar 26, 2023 · Updated Feb 20, 2025

Command injection in Ruijie Networks RG-EW1200 firmware EW_3.0(1)B11P204 allows remote attackers to execute system commands. The upgradeConfirm function processes the attacker-controlled params.path value as part of an operating-system command without neutralizing command metacharacters. No authentication or user interaction is required over the network, and successful exploitation grants command execution on the router.
