CVE-2023-36846

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 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.
