Technical details
The vulnerability is a path traversal flaw in the /attachRemoteFiles endpoint of GoAnywhere MFT versions prior to 7.10.2. An attacker with valid Web User credentials and both Secure Folders and Secure Mail permissions can manipulate file path parameters to escape the sandboxed home directory and access arbitrary files on the system. This requires authentication and specific permission grants, but no additional user interaction. The attack leads to unauthorized information disclosure. The vendor has released version 7.10.2 and later as a fix.
