CVE-2026-2260
Published: 10 February 2026
Summary
CVE-2026-2260 is a high-severity Command Injection (CWE-77) vulnerability in Dlink Dcs-931L Firmware. Its CVSS base score is 7.3 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 26.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SA-22 (Unsupported System Components) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-2260 is an OS command injection vulnerability (CWE-77, CWE-78) in D-Link DCS-931L cameras running firmware up to version 1.13.0. The flaw resides in an unspecified component of the /goform/setSysAdmin web endpoint, where manipulation of the AdminID argument enables arbitrary command execution on the underlying operating system. It carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) and was published on 2026-02-10.
The vulnerability can be exploited remotely by authenticated attackers possessing high privileges, such as administrative access to the device. Successful exploitation allows attackers to execute arbitrary operating system commands, potentially leading to full compromise of the camera, including high-impact confidentiality, integrity, and availability violations.
Advisories note that affected products are no longer supported by the maintainer, implying no official patches or firmware updates are available. A public proof-of-concept exploit is available on GitHub at https://github.com/cha0yang1/CVE/blob/main/DLinkRce.md, including a specific POC section, which could facilitate attacks on vulnerable devices.
This vulnerability has a publicly disclosed exploit, increasing the risk for exposed, end-of-life D-Link DCS-931L cameras still in use.

Why these techniques?
OS command injection in a web management endpoint directly enables remote exploitation of a public-facing application (T1190) to achieve arbitrary Unix shell command execution (T1059.004) with existing admin privileges.

Directly requires validation of all inputs to the /goform/setSysAdmin AdminID parameter, blocking the OS command injection vector at the point of entry.
Explicitly addresses continued use of the unsupported D-Link DCS-931L firmware (up to 1.13.0) that will never receive a vendor patch for this flaw.
Limits the number of accounts holding the high-privilege (PR:H) access required to reach the vulnerable setSysAdmin endpoint.
