In short

SimpleHelp remote support software versions 5.5.7 and earlier allow administrators to upload files to any location on the server through a specially crafted zip file. An attacker with admin access can exploit this to place malicious files and execute arbitrary code on the system.

Technical detail

The vulnerability exploits improper path validation during zip file extraction (zip slip attack), allowing authenticated admin users to bypass directory restrictions through relative path traversal in archive entries. This enables arbitrary code execution in the context of the SimpleHelp server process without additional user interaction.
