A Missing Authentication for Critical Function vulnerability in Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity.



With a specific request to

webauth_operation.php

that doesn't require authentication, an attacker is able to upload and download arbitrary files via J-Web, leading to a loss of

integrity or confidentiality, which may allow chaining to other vulnerabilities.
