CVE-2023-5074

What is this vulnerability?

CVE-2023-5074 is categorized as a critical Hard-coded Credentials flaw with a CVSS base score of 9.8. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.

Use of a static key to protect a JWT token used in user authentication can allow an for an authentication bypass in D-Link D-View 8 v2.0.1.28

This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Risk Assessment

Impact on Systems

✅ Credential Theft: Exposed secrets enable unauthorized access to infrastructure, cloud services, and third-party integrations.

✅ Compliance Violation: Leaking PII or credentials may violate GDPR, HIPAA, PCI-DSS, and SOC 2 requirements.

✅ Supply Chain Risk: Compromised credentials in public repositories can propagate to downstream consumers.

How to Fix and Mitigate CVE-2023-5074

1. Apply Vendor Patches: Upgrade affected components to their latest, non-vulnerable versions immediately.
2. Implement Input Validation: Ensure all user-supplied data is validated, sanitized, and type-checked before processing.
3. Deploy Runtime Protection: Use Precogs continuous monitoring to detect exploitation attempts in real time.
4. Audit Dependencies: Review and update all third-party libraries and transitive dependencies.

Defending with Precogs AI

D-Link D-View 8 uses a static, hardcoded cryptographic key to sign JWT tokens. Attackers extract this key to forge valid administrative tokens, bypassing authentication and taking over the network management system. Precogs PII & Secrets Scanner specifically identifies hardcoded cryptographic materials.

Use Precogs to continuously scan your codebase, binaries, APIs, and infrastructure for this vulnerability class and related attack patterns. Our AI-powered detection engine combines static analysis with threat intelligence to identify exploitable weaknesses before attackers do.
