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 that the affected D-Link DIR-605L and DIR-619L devices are no longer supported and no patches are available, organizations should prioritize replacing these routers with currently supported models that receive security updates. If immediate replacement is not feasible, network administrators should implement compensating controls such as isolating these devices from untrusted networks, restricting remote management access via firewall rules, and disabling any unnecessary wireless or remote configuration services. Monitoring network traffic for unusual activity targeting these devices can help detect exploitation attempts early. Additionally, changing default credentials and ensuring strong passwords are used can reduce risk, although this vulnerability does not require authentication. Network segmentation to separate legacy devices from critical infrastructure can limit potential damage. Finally, organizations should maintain an inventory of all network devices to identify and remediate unsupported hardware proactively.

Description

A security flaw has been discovered in D-Link DIR-605L and DIR-619L 2.06B01/2.13B01. Impacted is an unknown function of the component Wifi Setting Handler. Performing a manipulation results in information disclosure. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. This vulnerability only affects products that are no longer supported by the maintainer.

Impact

The primary impact of CVE-2026-2054 is unauthorized disclosure of sensitive information from vulnerable routers. This can compromise confidentiality by exposing network configuration details, wireless credentials, or other sensitive data stored or processed by the Wifi Setting Handler. Such information disclosure can facilitate further attacks, including network intrusion, man-in-the-middle attacks, or lateral movement within an organization’s network. Since the vulnerability can be exploited remotely without authentication, attackers can target exposed devices over the internet or local networks. The lack of vendor support and absence of patches increases the risk for organizations still using these legacy devices, as they remain exposed indefinitely. This may lead to data breaches, network compromise, and potential disruption of services relying on these routers. Organizations with these devices in critical network segments face elevated risks, especially if these routers are internet-facing or used in sensitive environments.
