CVE-2023-27216Public exploitNetwork attack vector

Root command execution via unsanitized settings fields

Published Apr 12, 2023 · Updated Jul 9, 2026

OS command injection in D-Link DSL-3782 1.03 allows remote authenticated users to execute arbitrary code as root through settings pages. The web interface inadequately sanitizes network, logging, port-forwarding, and static-route fields before inserting their values into shell scripts. Access to the web administration interface and valid credentials are required, after which injected commands run with root privileges.
