What is CVE-2020-36973?

PDW File Browser version 1.3 is susceptible to a remote code execution vulnerability, allowing authenticated users to exploit path traversal techniques to upload and rename malicious webshell files. By double-encoding path segments, an attacker can craft a file upload request that leads to unauthorized file placements in accessible directories. This type of attack can facilitate further exploitation, as attackers can run arbitrary code on the server by effectively disguising the malicious payload as a legitimate file.
