Severity ?
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.
