CVE-2023-49695

Administrator command execution via crafted request

Published Dec 12, 2023 · Updated Oct 8, 2024

OS command injection in ELECOM WRC-X3000GS-series routers allows attackers to execute arbitrary OS commands through crafted requests. ELECOM and JPCERT/CC have not disclosed the affected request handler, parameter, or operation that incorporates request data into an OS command. Exploitation requires a logged-in administrator on an adjacent network and grants command execution with the router firmware's privileges.
