Summary

CVE-2024-10214 is a low-severity Incorrect Implementation of Authentication Algorithm (CWE-303) vulnerability in Mattermost Mattermost. Its CVSS base score is 3.5 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 31th 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 SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation at post-design stages directly uncovers incorrect implementations of required authentication algorithms.

Requiring documented development processes, standards, and tools reduces the chance that an established authentication algorithm is coded incorrectly.

degrades

Cryptography control addresses proper use of authentication algorithms but is broader than authentication alone.

blocks

A.8.25 mandates security requirements, secure coding, checkpoints, testing and developer capability in the SDLC which reaches incorrect algorithm implementation for auth (via secure coding, testing and vuln prevention/fixing), but this is only a minority slice of the weakness class as most instances arise from flawed design/requirements rather than implementation errors caught in dev.

blocks

Application security requirements can specify correct authentication algorithm use but do not guarantee correct implementation.

prevents

Secure coding practices reduce the likelihood of incorrect authentication algorithm implementation.

finds

Security testing can detect flawed authentication implementations but does not prevent them by itself.
