Summary

CVE-2024-0456 is a medium-severity Forced Browsing (CWE-425) vulnerability in Gitlab Gitlab. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Proc Filesystem (T1003.007); ranked at the 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-24 (Access Control Decisions) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly requires enforcement of authorizations for access to resources such as URLs, scripts, and files, structurally preventing forced browsing.

AC-24 Access Control Decisions good match

AC-24 requires that access-control decisions be applied to every request, addressing the missing enforcement on restricted URLs.

AC-6 Least Privilege partial match

AC-6 requires restricting authorizations to the minimum needed, reducing the set of resources that must be protected against direct requests.

Mitigating Controls (NIST CSF 2.0) AI

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

PR.AA-05 partial match
blocks

Directly requires policy-driven definition, enforcement, and review of authorizations on resources such as URLs.

PR.IR-01 partial match
blocks

Protects environments from unauthorized logical access, which includes preventing direct requests to restricted paths.

A.5.14 Information transfer partial match
removes
A.5.15 Access control partial match
blocks

A.5.15 directly requires defining/implementing access control rules, authorization, need-to-know, and restrictions that enforce appropriate access on all URLs/resources, which stops forced browsing exploitation even if the flaw remains; remainder is bounded to non-authorization cases like path traversal or CSRF (per AC-3 anchor).
