CVE-2022-24883
April 26, 2022
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). Prior to version 2.7.0, server side authentication against a "SAM" file might be successful for invalid credentials if the server has configured an invalid "SAM" file path. FreeRDP based clients are not affected. RDP server implementations using FreeRDP to authenticate against a "SAM" file are affected. Version 2.7.0 contains a fix for this issue. As a workaround, use custom authentication via "HashCallback" and/or ensure the "SAM" database path configured is valid and the application has file handles left.
