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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within 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 6 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 DIR-605L is end of life. Replace it, or isolate it from untrusted networks until you can.

AI-suggested

Given the absence of vendor patches due to end-of-life status, organizations should prioritize replacing affected D-Link DIR-605L and DIR-619L routers with currently supported models that receive security updates. If immediate replacement is not feasible, network administrators should implement strict network segmentation to isolate vulnerable devices from untrusted networks, especially the internet. Employing firewall rules to restrict access to router management interfaces and the /wan_connection_status.asp endpoint can reduce exposure. Monitoring network traffic for unusual requests targeting these routers may help detect exploitation attempts. Additionally, disabling unnecessary services or features on the routers, if possible, can minimize attack surface. Organizations should also conduct asset inventories to identify all affected devices and assess their exposure. Finally, educating network staff about the risks of using unsupported hardware and the importance of timely device lifecycle management will help prevent similar risks in the future.

Description

A security vulnerability has been detected in D-Link DIR-605L and DIR-619L 2.06B01/2.13B01. The impacted element is an unknown function of the file /wan_connection_status.asp of the component DHCP Connection Status Handler. The manipulation leads to information disclosure. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. This vulnerability only affects products that are no longer supported by the maintainer.

Impact

The primary impact of CVE-2026-2056 is unauthorized disclosure of sensitive information from affected D-Link routers. This information leakage can aid attackers in mapping network topology, identifying device configurations, or gathering credentials, which may facilitate subsequent attacks such as network intrusion, lateral movement, or targeted exploitation of other vulnerabilities. Since the vulnerability is remotely exploitable without authentication or user interaction, attackers can potentially scan and target vulnerable devices over the internet or internal networks. The lack of vendor support and patches increases the risk for organizations still operating these legacy devices, as they remain exposed indefinitely. While the vulnerability does not directly allow system compromise or denial of service, the information disclosed could be leveraged in multi-stage attacks, increasing overall risk. Organizations relying on these routers for critical network functions may face increased exposure to cyber espionage, data breaches, or disruption through follow-on attacks. The impact is particularly significant for environments where these devices are internet-facing or lack adequate network segmentation.
