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





With a specific request to installAppPackage.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.

* All versions prior to 20.4R3-S8;
* 21.1 versions 21.1R1 and later;
