HIGH ⌖ ON CISA KEV · EXPLOITEDJuniper Junos OS EX Series missing authentication for critical function allows arbitrary file upload.
An unauthenticated attacker can upload arbitrary files via J-Web on Juniper Junos OS EX Series, leading to potential file system integrity loss and further vulnerabilities. This is a critical security flaw that could allow remote code execution and should be patched immediately.
Shame score — The vulnerability is actively exploited and allows for remote code execution, posing a significant risk to the integrity of the file system.
▸ RECOMMENDED ACTION Actively exploited (CISA KEV) — remediate now, ahead of your normal patch cycle.
Juniper Junos OS on EX Series contains a missing authentication for critical function vulnerability that 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.
