CVE-2024-42330: Zabbix

Critical severity, CVSS 9.1. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Zabbix Zabbix: from 5.0.0, before 5.4.6 (fixed in 5.4.6); from 6.0.0, before 6.0.34 (fixed in 6.0.34); from 6.4.0, before 6.4.19 (fixed in 6.4.19); from 7.0.0, before 7.0.4 (fixed in 7.0.4)
