Juniper Junos OS EX Series Missing Authentication for Critical Function Vulnerability
Vendor: Juniper
Product: Junos OS
Added: 2023-11-13
Due Date: 2023-11-17
Description:
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.
Required Action:
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
