CVE-2020-25078
Overview
This vulnerability is an information disclosure flaw caused by improper access control on the /config/getuser HTTP endpoint in certain D-Link camera firmware versions. The endpoint does not require authentication, allowing unauthenticated remote requests to retrieve sensitive configuration data. The affected component is the web management interface of specific D-Link camera models' firmware, which exposes administrator credentials through this unsecured API path.
Vulnerability Description
An issue was discovered on D-Link DCS-2530L before 1.06.01 Hotfix and DCS-2670L through 2.02 devices. The unauthenticated /config/getuser endpoint allows for remote administrator password disclosure.
Impact
An attacker can remotely retrieve the administrator password of the affected D-Link cameras without any authentication or user interaction. This unauthorized disclosure enables full administrative access to the device, allowing the attacker to control camera functions, modify settings, and potentially pivot within the network. The exposure of credentials compromises device confidentiality and integrity, increasing the risk of surveillance, data exfiltration, or further network exploitation.
Solution
D-Link has released firmware updates addressing this vulnerability, including version 1.06.01 Hotfix for the DCS-2530L and version 2.02 or later for the DCS-2670L. Users should apply these specific firmware updates to affected devices as detailed in the vendor advisory (SAP10180) available at https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10180. No alternative workarounds were provided; updating firmware is the recommended remediation step.
