CVE-2024-26258

Authenticated command execution via crafted router request

Published Apr 4, 2024 · Updated May 12, 2026

OS command injection in affected ELECOM wireless LAN routers allows remote authenticated users on an adjacent network to execute commands. ELECOM and JPCERT/CC have not disclosed the request parameter, handler, or command-construction operation. Valid credentials and adjacent-network access are required; successful exploitation grants arbitrary command execution in the router's operating context.
