An executable used in Rockwell Automation ThinManager ThinServer can be configured to enable an API feature in the HTTPS Server Settings. This feature is disabled by default. When the API is enabled and handling requests, a path traversal vulnerability exists that allows a remote actor to leverage the privileges of the server’s file system and read arbitrary files stored in it. A malicious user could exploit this vulnerability by executing a path that contains manipulating variables.

In affected versions, path traversal exists when processing a message of type 8 in Rockwell Automation's ThinManager ThinServer. An unauthenticated remote attacker can exploit this vulnerability to download arbitrary files on the disk drive where ThinServer.exe is installed.

In affected versions, a path traversal exists when processing a message in Rockwell Automation's ThinManager ThinServer. An unauthenticated remote attacker could potentially exploit this vulnerability to upload arbitrary files to any directory on the disk drive where ThinServer.exe is installed. The attacker could overwrite existing executable files with attacker-controlled, malicious contents, potentially causing remote code execution.
