The vulnerability was introduced in SnagIT Windows 12.4.1. TechSmith Relay Classic Recorder prior to 5.2.1 on Windows is vulnerable.

UploaderService in SnagIT 2019.1.2 allows elevation of privilege by placing an invalid presentation file in %PROGRAMDATA%\TechSmith\TechSmith Recorder\QueuedPresentations and then creating a symbolic link in %PROGRAMDATA%\Techsmith\TechSmith Recorder\InvalidPresentations that points to an arbitrary folder with an arbitrary file name. In TechSmith SnagIt 11.2.1 through 20.0.3, an XML External Entity (XXE) injection issue exists that would allow a local attacker to exfiltrate data under the local Administrator account.
