Summary

CVE-2026-2163 is a medium-severity Injection (CWE-74) vulnerability in Dlink Dir-600 Firmware. Its CVSS base score is 5.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-2163 is a command injection vulnerability (CWE-74, CWE-77) in the ssdp.cgi file of D-Link DIR-600 routers, affecting versions up to 2.15WWb02. The flaw resides in unknown code that improperly handles manipulation of the arguments HTTP_ST, REMOTE_ADDR, REMOTE_PORT, and SERVER_ID, enabling attackers to inject and execute arbitrary commands.

The vulnerability is exploitable remotely over the network (AV:N) with low complexity (AC:L) but requires high privileges (PR:H) and no user interaction (UI:N), resulting in unchanged scope (S:U) and low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), for an overall CVSS v3.1 score of 4.7. Attackers with sufficient access can achieve remote arbitrary command execution.

Advisories note that affected products are no longer supported by the maintainer, with no patches available. References include GitHub proof-of-concept exploits demonstrating remote arbitrary command execution and VulDB entries (ctiid.344865, id.344865) providing further details on the issue.

A public exploit is available and might be used against vulnerable devices.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 Information Input Validation good match

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include proper neutralization and safe command construction practices.

A.8.28 Secure coding mostly match
prevents

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches injection vulnerabilities before release.

A.8.15 Logging partial match
finds

Logging supports detection of injection attempts but does not prevent the weakness.

A.8.16 Monitoring activities partial match
finds

Monitoring activities can identify active injection attacks after they occur.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection attacks in software design.
