Description

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A rogue Remote Desktop Protocol (RDP) server can exploit an off-by-one error in the path traversal filter. This allows the server to read, list, or write files in the directory above the client's shared folder when the victim connects with drive redirection enabled. This vulnerability can lead to unauthorized information disclosure and arbitrary file modification.
