Summary

CVE-2024-2004 is a low-severity Interpretation Conflict (CWE-436) vulnerability in Apple Macos. Its CVSS base score is 3.5 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 25% 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-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

When a protocol selection parameter option disables all protocols without adding any then the default set of protocols would remain in the allowed set due to an error in the logic for removing protocols. The below command would perform a…

request to curl.se with a plaintext protocol which has been explicitly disabled. curl --proto -all,-http http://curl.se The flaw is only present if the set of selected protocols disables the entire set of available protocols, in itself a command with no practical use and therefore unlikely to be encountered in real situations. The curl security team has thus assessed this to be low severity bug.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover cases where two products interpret the same inputs or state transitions differently.

Strict, consistently applied input validation reduces the chance that one product will accept data the other product rejects or interprets differently.

Applying security engineering principles during design can require unambiguous protocol and data-format specifications that eliminate divergent interpretations between products.

Secure SDLC practices directly reduce the chance of introducing parser or state-machine inconsistencies.

DE.AE-03 partial match

finds

Security testing can detect and correct cases where one component misinterprets another’s state or messages.

prevents

Secure development lifecycle can require consistent interface contracts and canonicalization rules that reduce interpretation conflicts between components.

prevents

Explicit application security requirements can mandate unambiguous protocol and data-format specifications that prevent divergent interpretations.

prevents

Secure architecture principles include well-defined component boundaries and shared data models that limit conflicting state perceptions.

prevents

Secure coding standards can enforce canonical input handling and strict protocol compliance to avoid misinterpretation between products.
