Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Enforces rules governing access to the system and its data from external systems based on established trust relationships.
This control requires verifying that a sharing partner's access authorizations match the information's restrictions before sharing occurs.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct unauthenticated remote access to device config/status page enables public-facing app exploitation and network device config data retrieval.
NVD 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.

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.
Deeper analysisAI
CVE-2026-2056 is an information disclosure vulnerability affecting D-Link DIR-605L and DIR-619L routers running firmware versions 2.06B01 or 2.13B01. The issue resides in an unknown function within the file /wan_connection_status.asp, part of the DHCP Connection Status Handler component. Manipulation of this function enables the exposure of sensitive information, with a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), mapped to CWEs 200 and 284.
The vulnerability allows remote attackers to exploit it over the network with low complexity and no required privileges or user interaction. Successful exploitation results in limited disclosure of confidential information, such as details potentially related to DHCP connection status, without impacting integrity or availability.
References, including proof-of-concept exploits on GitHub and entries on VulDB, confirm public disclosure of the exploit. The affected products are no longer supported by the maintainer, leaving no official patches or mitigations available; security practitioners should isolate or retire these end-of-life devices to prevent exploitation.
