CVE-2022-24883

Summary

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.
