Summary

CVE-2024-3845 is a medium-severity Improperly Implemented Security Check for Standard (CWE-358) vulnerability in Fedoraproject Fedora. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Downgrade Attack (T1689); ranked in the top 48% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-10 (Developer Configuration Management) and SA-11 (Developer Testing and Evaluation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

Requires developer configuration management that tracks and controls changes to both design and code, reducing divergence between them.

Developer testing and evaluation activities directly examine whether the delivered implementation satisfies documented design and requirements.

Requires the developer to follow a documented development process that explicitly includes maintaining consistency between design artifacts and implementation.

Mandates use of an SDLC that incorporates security and privacy activities, thereby structuring development to keep implementation aligned with documented design.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require correct implementation of standardized security checks and algorithms.

ID.RA-07 partial match
prevents

Formal change and exception tracking reduces uncontrolled drift from documented designs but does not verify consistency.

PR.PS-01 partial match
prevents

Configuration management verifies deployed state against documented baselines, catching some but not all design-implementation drift.

finds

Security testing in development and acceptance validates that required security checks function as specified.

prevents

Change management can catch drift after the fact, but does not guarantee initial implementation matches design.

degrades

Documented operating procedures help keep implementation aligned with stated design, but do not enforce design-level consistency.

prevents

Project-level design-to-implementation traceability directly reduces divergence between documented design and delivered code.

prevents

Use of cryptography control depends on correct implementation of standardized cryptographic checks.

prevents

Secure development life cycle mandates verification that security checks required by standards are correctly implemented.
