CVE-2023-5074
Published: 20 September 2023
Summary
CVE-2023-5074 is a critical-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Dlink D-View 8. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 0.3% 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-2023-5074 is an authentication bypass vulnerability stemming from the use of a static key to protect JWT tokens in the D-Link D-View 8 network management software, specifically version 2.0.1.28. The issue is tracked under CWE-798 and carries a CVSS 3.1 base score of 9.8, reflecting network-accessible exploitation with no required credentials or user interaction and full impact on confidentiality, integrity, and availability.
An unauthenticated remote attacker can exploit the hardcoded key to forge valid JWT tokens, thereby bypassing authentication controls and gaining administrative access to the affected D-View instance. Successful exploitation allows the attacker to perform any action available to a legitimate administrator, including device management and configuration changes across the monitored network.
The referenced Tenable advisory (TRA-2023-32) is the primary public source detailing the flaw; no vendor patch or official mitigation guidance is provided in the available references. The associated EPSS score remains elevated, with a current value of 0.9150 and a recorded peak of 0.9258, indicating sustained exploitation interest following disclosure.

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.
Enables users to notice when hard-coded credentials have been exploited for unauthorized access.
Security training explicitly warns against hard-coded credentials, lowering their use in systems.
Policy and procedures prohibit hard-coded credentials in favor of managed authentication.
External identity providers eliminate the need for hard-coded credentials in applications.
Changing default authenticators prior to first use and protecting content prevents use of hard-coded credentials.
Central credential stores and rotation policies remove the need for hard-coded credentials in configuration files or code.
Intelligence programs surface reports of campaigns that abuse hard-coded credentials in products, prompting removal or replacement and thereby reducing successful exploitation.
Planned investment enables secure credential storage and management systems instead of hard-coded credentials.
