Name of the Vulnerable Software and Affected Versions Altec DocLink version 4.0.336.0

Description The software has insecure .NET Remoting endpoints exposed over TCP and HTTP/SOAP via Altec.RDCHostService.exe using the ObjectURI "doclinkServer.soap". The service does not require authentication and is vulnerable to unsafe object unmarshalling. This allows remote attackers to read arbitrary files from the underlying system by specifying local file paths. Attackers can also coerce SMB authentication via UNC paths and write arbitrary files to server locations. Because writable paths may be web-accessible under IIS, this can result in unauthenticated remote code execution or denial of service through file overwrite.

Recommendations Update to a newer version that contains a fix for this vulnerability.
