📄 Description (English)

Juniper Junos OS EX Series Missing Authentication for Critical Function Vulnerability — 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.

🤖 AI Executive Summary

Juniper Junos OS EX Series lacks authentication for the installAppPackage.php function, allowing unauthenticated attackers to upload arbitrary files via J-Web. This vulnerability can compromise file system integrity and potentially enable exploitation of additional vulnerabilities.
