Summary

CVE-2024-41958 is a medium-severity Incorrect Comparison (CWE-697) vulnerability in Mailcow Mailcow\. Its CVSS base score is 6.6 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Obfuscated Files or Information (T1027); ranked in the top 39% of CVEs by exploit likelihood; 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 AC-25 (Reference Monitor) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

mailcow: dockerized, an open source groupware and email suite based on Docker, contains a flaw in its two-factor authentication mechanism. The vulnerability allows an authenticated attacker to bypass 2FA checks and obtain access to other accounts that are otherwise protected by 2FA.

Exploitation requires the attacker to already hold valid credentials for both an account under their control and a target account that has 2FA enabled. With those credentials the attacker can circumvent the 2FA process and reach the protected account. The issue is rated 6.6 under CVSS 3.1.

The flaw was corrected in the 2024-07 release. Administrators are advised to upgrade, as the project states that no workarounds exist. Further information is provided in the GitHub security advisory GHSA-4fcc-q245-qqgg and the referenced commit. The EPSS score has remained flat at 0.3031 with no material increase after disclosure.

Vulnerability Data

mailcow: dockerized is an open source groupware/email suite based on docker. A vulnerability has been discovered in the two-factor authentication (2FA) mechanism. This flaw allows an authenticated attacker to bypass the 2FA protection, enabling unauthorized access to other accounts that…

are otherwise secured with 2FA. To exploit this vulnerability, the attacker must first have access to an account within the system and possess the credentials of the target account that has 2FA enabled. By leveraging these credentials, the attacker can circumvent the 2FA process and gain access to the protected account. This issue has been addressed in the `2024-07` release. All users are advised to upgrade. There are no known workarounds for this vulnerability.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation directly exercises security-relevant comparisons to discover incorrect logic.

AC-25 Reference Monitor partial match

A reference monitor must be small and correct, structurally limiting the chance of flawed comparison logic in authorization decisions.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles require correct implementation of comparison logic used for access and authentication decisions.
