Authenticated Command Injection in D-Link DWR Routers

IdentifiersCVE-2018-10823CWE-78· Improper Neutralization of Special…

CVE-2018-10823 is a command injection vulnerability affecting multiple D-Link router models, including DWR-116 through 1.06, DWR-512 through 2.02, DWR-712 through 2.02, DWR-912 through 2.02, DWR-921 through 2.02, and DWR-111 through 1.01. An authenticated attacker can inject shell commands via the Sip parameter of the chkisg.htm page. Improper neutralization of attacker-controlled input allows the supplied parameter value to be interpreted by the underlying system shell, resulting in arbitrary command execution on the device. Successful exploitation enables direct interaction with the router operating environment and can lead to full control of device internals.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary code or shell command execution on the affected router with the privileges of the vulnerable web management component. This can enable complete compromise of the device, including modification of configuration, execution of additional payloads, persistence, traffic interception or manipulation, use of the router as a botnet node, and disruption of normal network services.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to the router management interface to trusted administrative networks only, disable remote administration from untrusted networks, and enforce strong unique administrative credentials to reduce the likelihood of authenticated exploitation. Where possible, place management interfaces behind VPN access or network ACLs, monitor for unexpected configuration changes, and isolate vulnerable devices until patched or replaced.

Remediation

Patch, then assume compromise.

Upgrade affected D-Link DWR devices to a vendor-fixed firmware release if one is available for the specific model. If no supported fixed firmware is available, replace end-of-life devices with supported hardware. Review administrative credentials, rotate passwords after remediation, and validate device integrity and configuration because successful exploitation may result in full device compromise.
