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 user.php that doesn’t require authentication an attacker is able to upload arbitrary files via J-Web, leading to a loss of

integrity

for a certain

part of the file system, which may allow chaining to other vulnerabilities.
