  7. Open Services, and select Stop the Dameware Server service.
  8. If you have Dameware Proxy installed on a separate machine (Dameware Server installed on another machine):
    a) In the opened configuration wizard, turn on the Dameware Proxy component.
    b) Pair the Dameware Proxy component with Dameware Server (on the server side).
  9. If you have Dameware Proxy on the same machine as the Dameware Server:
    a) In the opened Configuration wizard, turn on the Dameware Proxy component.
    b) Turn on the Dameware Server component.

Install the hotfix on Dameware Mini Remote Control

  • If you have MRC x86 version, copy the contents of the MRCx86 folder to the MRC installation folder on the computer.
  • The default location of the folder for Centralized Version as a part of the Dameware Server installation is as follows: C:\Program Files (x86)\SolarWinds\DameWare Remote Support
  • If you have MRC x64 version, copy the contents of MRCx64 folder to the MRC installation folder on the computer. By default, the installation folder location is as follows: C:\Program Files\SolarWinds\DameWare Mini Remote Control x64
  • Warning: If you have the remote control agent already installed on your remote machines from the Dameware 12.1 release, remove and install it manually from MRC (with Hotfix2 applied).

Uninstall the hotfix

  1. If you want to uninstall Hotfix 2, you need to back up files (which will be replaced during the installation process) and save them in a separate location.
  2. Follow the same steps described in the installation process, but instead, use your backed up files. The hotfix is then uninstalled.

michael.tran​ I think to resolve the vulnerability, the hotfix needs to be applied on administrator machines running Remote Control/Remote Support, as well as the agents on the client machines. The instructions given are very unclear about this, our vulnerability scanner confirmed that just installing the 12.1 agent does not resolve the vulnerability. There are also no instructions on how to apply the hotfix to agents without manually connecting to each one with a patched version of Remote Control. I'm trying to manually copy the updated files for the agent service (DWRCSE.dll, DWRCS.exe, DWRCSRSS.dll, DDLib.dll) to C:\Windows\dwrcs to find a way patch it in a way that will scale out to our 1000+ machines that need this, but not having much luck.

Since this hotfix was released in May, it's inexcusable and sloppy on SolarWinds' part to ask us to patch individual files in a hacky way like this. They need to release updated installers, that easily could have been done in this timespan . There's also no indication about the updated version ( in Control Panel once installed, which makes it extremely difficult to keep track of which of our endpoints have this patch applied.

This is an extremely poor way to handle a security issue and to release software updates.

Need some clarification, does this mean the hotfix need to be installed on DameWare Proxy server, all machines with Dameware MRC installed, and all machines with Remote Control Agent Service already installed? We have the agent deployed via SCCM, so we have to rebuild the Dameware Agent Service and redeploy to all remote machines?
