CVE-2024-53553 is an authentication bypass vulnerability affecting OPEXUS FOIAXPRESS PUBLIC ACCESS LINK version 11.1.0. The flaw, classified under CWE-863 (Incorrect Authorization), allows attackers to circumvent authentication mechanisms through specially crafted web requests. It has been assigned a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating critical severity due to its network accessibility, low complexity, lack of required privileges or user interaction, and potential for high confidentiality and integrity impacts.

Remote attackers with network access to the affected system can exploit this vulnerability without authentication by sending crafted requests to the public access link component. Successful exploitation enables unauthorized access to restricted resources, potentially allowing attackers to view or modify sensitive information protected by the authentication controls.

Further technical details, including potential proof-of-concept exploits, are documented in the referenced GitHub repository at https://github.com/Turbul3nce/Vulnerability.Research/tree/main/CVE-2024-53553.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.

AC-24 Access Control Decisions good match

AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.

AC-25 Reference Monitor good match

A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.

AC-6 Least Privilege partial match

Least-privilege assignments shrink the set of authorizations that must be checked correctly, limiting exposure to flawed checks.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.15 Access control partial match
prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

A.5.18 Access rights partial match
prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

A.8.3 Information access restriction partial match
prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
