Summary
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.
This issue affects Juniper Networks Junos OS on EX Series:
* All versions prior to 20.4R3-S8;
* 21.1 versions 21.1R1 and later;
* 21.2 versions prior to 21.2R3-S6;
* 21.3 versions
prior to
21.3R3-S5;
* 21.4 versions
prior to
21.4R3-S4;
* 22.1 versions
prior to
22.1R3-S3;
* 22.2 versions
prior to
22.2R3-S1;
* 22.3 versions
prior to
22.3R2-S2, 22.3R3;
* 22.4 versions
prior to
22.4R2-S1, 22.4R3.

Summary
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:

Summary
A PHP External Variable Modification vulnerability in J-Web of Juniper Networks Junos OS on EX Series allows an unauthenticated, network-based attacker to control certain, important environment variables.
Using a crafted request an attacker is able to modify
certain PHP environment variables leading to partial loss of integrity, which may allow chaining to other vulnerabilities.
This issue affects Juniper Networks Junos OS on EX Series:
* All versions prior to 20.4R3-S9;
* 21.1 versions 21.1R1 and later;
* 21.2 versions prior to 21.2R3-S7;
* 21.3 versions
prior to
21.3R3-S5;
* 21.4 versions
