CVE-2025-14528
Published: 11 December 2025
Summary
CVE-2025-14528 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Dlink Dir-803 Firmware. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 7.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2025-14528 affects the D-Link DIR-803 router up to firmware version 1.04 in the Configuration Handler component. The issue resides in the /getcfg.php file, where improper handling of the AUTHORIZED_GROUP argument permits unauthorized access to configuration data, resulting in information disclosure.
Remote attackers can exploit the flaw without authentication or user interaction to retrieve sensitive configuration details. A public proof-of-concept is available, and the vulnerability is restricted to products that have reached end-of-life status with no ongoing vendor support.
The listed references consist of exploit documentation hosted on GitHub along with entries in the VulDB database; no official patches or mitigation guidance are referenced, consistent with the unsupported status of the affected hardware.
The associated EPSS values remain low, moving only from 0.0899 to a peak of 0.0935.

Why these techniques?
The authentication bypass vulnerability in the router's /getcfg.php allows remote unauthenticated information disclosure of configurations (CWE-200), enabling exploitation of a public-facing application (T1190) to gather victim host information (T1592) and perform network device configuration dumps (T1602.002).

Mitigating Controls
Likely Mitigating Controls AI
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.
