Smart Card not working over Remote Desktop

Max | Last updated: Jan 19, 2017 05:13PM UTC

We use ActivClient on our local and remote machines for Smart Card authentication. This works fine with IE and Firefox, both local and remote. When Burp is run on the remote machine, it accepts the pin code and appears to work, but never shows any certificates. Technical details that may matter: Remote host is 32-bit Running jre1.8.0_112 using acpkcs211.dll as the library Local host is 64-bit

We're not quite clear on what your set-up is. When Burp is running on the remote machine, is the device physically connected to that machine, or is it being shared over RDP? Burp uses standard platform APIs for accessing smart cards, and if these aren't able to see/read the card from the remote machine, then there might not be anything that Burp can do.

The smart card is on the local machine and shared over RDP. Other applications are able to read the smart card, such as Internet Explorer. It appears it may be an issue with the library that ActivClient is providing to Burp, but the lack of error messages makes it impossible to tell.
