CVE-2026-82595Public exploitNetwork attack vector

Root command execution via unsanitized sysCmd

Published Aug 30, 2026 · Updated Aug 30, 2026

Command injection in D-Link DIR-825M 1.1.8 allows remote authenticated users to execute root shell commands via a crafted sysCmd value. sub_456CF4 places the POST parameter directly into an snprintf-built command string and passes it to system() without validation or escaping. Low-privileged access to the router management interface is required; injected shell operators permit commands of up to 76 bytes to run as root.
