Unauthenticated code execution via unsanitized unmount path
Published Oct 21, 2024 · Updated Oct 22, 2024
Command injection in DCME-320-L 9.3.2.114 and earlier allows remote attackers to execute arbitrary code through its web interface. The log_u_umount.php endpoint accepts action=umount and passes the attacker-controlled path through umountdisk directly to exec after string concatenation. No authentication or user interaction is required; a network-reachable management interface therefore exposes arbitrary command execution on the gateway.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
