# CVE-2024-21620

> 8.8 HIGH

## Beschreibung

An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in J-Web of Juniper Networks Junos OS on SRX Series and EX Series allows an attacker to construct a URL that when visited by another user enables the attacker to execute commands with the target's permissions, including an administrator.

A specific invocation of the emit_debug_note method in webauth_operation.php will echo back the data it receives.

This issue affects Juniper Networks Junos OS on SRX Series and EX Series:
  *  All versions earlier than 20.4R3-S10;
  *  21.2 versions earlier than 21.2R3-S8;
