CVE-2024-39565 Information

Description

An Improper Neutralization of Data within XPath Expressions (‘XPath Injection’) vulnerability in J-Web shipped with Juniper Networks Junos OS allows an unauthenticated network-based attacker to execute remote commands on the target device. 

While an administrator is logged into a J-Web session or has previously logged in and subsequently logged out of their J-Web session the attacker can arbitrarily execute commands on the target device with the other user’s credentials. In the worst case the attacker will have full control over the device. This issue affects Junos OS:
