Summary

CVE-2024-2466 is a medium-severity Improper Validation of Certificate with Host Mismatch (CWE-297) vulnerability in Apple Macos. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 27% 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 SC-23 (Session Authenticity) and SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Vulnerability Data

libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as…

an IP address, therefore completely skipping the certificate check. This affects all uses of TLS protocols (HTTPS, FTPS, IMAPS, POPS3, SMTPS, etc).

Mitigating Controls (NIST 800-53 r5) AI

SC-23 Session Authenticity good match

Protecting session authenticity structurally requires proper certificate validation to bind the presented certificate to the intended host.

SC-8 Transmission Confidentiality and Integrity good match

Requiring confidentiality and integrity of transmitted data necessitates correct TLS certificate validation with host-name checking.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles require correct implementation of certificate validation (including hostname matching) when cryptography is used.
