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.

This issue affects Juniper Networks Junos OS on SRX Series:

*

21.2 versions prior to 21.2R3-S8; * 21.4

versions prior to

21.4R3-S6; * 22.1
