M-Files Server: Incorrect Implementation of Authentication Algorithm
CVE-2024-10127 is a critical-severity incorrect implementation of authentication algorithm vulnerability in M-Files Server from M-Files, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 24.11 as the first without the flaw, so updating M-Files Server to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.61% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update M-Files Server to 24.11 or a later version.
- Update m-files to 24.11 or a later version.
- Read the advisory on empower.m-files.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions

|---|---|---|---|
| M-Files | M-Files Server | before 24.11 | 24.11 |
| M-files | m-files | before 24.11 | 24.11 |

Official description
Authentication bypass condition in LDAP authentication in M-Files server versions before 24.11 supported usage of OpenLDAP configurations that allowed user authentication without a password when the LDAP server itself had the vulnerable configuration.

The underlying weakness: Incorrect Implementation of Authentication Algorithm
The requirements for the product dictate the use of an established authentication algorithm, but the implementation of the algorithm is incorrect.
