Unauthenticated command execution via Command1 HTTP header
Published Mar 19, 2024 · Updated Aug 19, 2024
Command injection in Ruijie Networks RG-NBS2009G-P firmware through 20240305 allows remote attackers to execute commands over HTTP. The unauthenticated /EXCU_SHELL handler treats the attacker-controlled Command1 HTTP header as a CLI command rather than data. No credentials or user interaction are required; successful exploitation runs arbitrary commands on the switch and can read or alter data or interrupt service.
