CVE-2024-42330

Zabbix vulnerability

9.1 CRITICALEPSS 0.95%
  1. Published27 Nov 2024

Description

The HttpRequest object allows to get the HTTP headers from the server's response after sending the request. The problem is that the returned strings are created directly from the data returned by the server and are not correctly encoded for JavaScript. This allows to create internal strings that can be used to access hidden properties of objects.
