CVE-2024-36103

Arbitrary command execution via crafted administrative request

Published Jun 12, 2024 · Updated Aug 2, 2024

OS command injection in ELECOM WRC-X5400GS-B and WRC-X5400GSA-B 1.0.10 and earlier allows remote authenticated users to execute commands. A specially crafted request reaches an undisclosed router interface that passes attacker-controlled data to an operating-system command without adequate neutralization. Administrative access from an adjacent network is required, and successful exploitation grants arbitrary command execution on the router.
