Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

No fix will be released: D-Link DCS-931L is end of life. Replace it, or isolate it from untrusted networks until you can.

AI-suggested

Since no official patches are available due to the device being out of support, organizations should prioritize replacing D-Link DCS-931L cameras with newer, supported models that receive security updates. If immediate replacement is not feasible, network-level mitigations should be implemented: restrict access to the device management interface using firewalls or VLAN segmentation, disable remote administration where possible, and enforce strong authentication controls to limit privilege escalation. Monitoring network traffic for unusual commands or connections to/from these devices can help detect exploitation attempts. Additionally, consider isolating legacy devices on separate network segments to minimize potential lateral movement. Regularly audit and inventory all IoT and surveillance devices to identify unsupported hardware and plan for timely upgrades. Employ network intrusion detection systems tuned to detect command injection patterns targeting these cameras.

Description

A vulnerability was found in D-Link DCS-931L up to 1.13.0. Impacted is the function doSystem of the file /setSystemAdmin. Performing a manipulation of the argument AdminID results in command injection. The attack may be initiated remotely. The exploit has been made public and could be used. This vulnerability only affects products that are no longer supported by the maintainer.

Impact

The primary impact of CVE-2026-2227 is unauthorized remote command execution on affected D-Link DCS-931L devices. This can lead to complete device compromise, allowing attackers to manipulate camera settings, intercept or disrupt video feeds, and use the device as a foothold for lateral movement within corporate or home networks. Given the device's role in surveillance and security, exploitation could result in privacy violations, espionage, or sabotage. The lack of vendor support and patches increases the risk for organizations still deploying these legacy cameras. Additionally, compromised devices could be enlisted into botnets or used to launch further attacks. The medium CVSS score reflects moderate impact and exploitation complexity, but the real-world risk is heightened by the public availability of exploit code and the device's network exposure.
