CVE-2022-24917: 
Zabbix Server vulnerability analysis and mitigation

CVE-2022-24917 is a security vulnerability discovered in Zabbix, a network monitoring solution. The vulnerability was disclosed in February 2022 and affects multiple versions of Zabbix Frontend (versions 4.0.0-4.0.38, 5.0.0-5.0.20, 5.4.0-5.4.10). The issue allows an authenticated user to create a link with reflected Javascript code inside it for the services' page and send it to other users (Zabbix Support).

The vulnerability is classified as a Reflected Cross-Site Scripting (XSS) issue with a CVSS score of 3.7, indicating Low severity. The payload can only be executed with a known CSRF token value of the victim, which is changed periodically and is difficult to predict. This security control adds a layer of complexity to successful exploitation (Zabbix Support).

When successfully exploited, the malicious code gains access to all the same objects as the rest of the web page and can make arbitrary modifications to the contents of the page being displayed to a victim during social engineering attacks (NVD, Zabbix Support).

The vulnerability has been fixed in multiple Zabbix versions including 4.0.39rc1, 5.0.21rc1, 5.4.11rc1, and 6.0.1rc1. Organizations are advised to upgrade to these or later versions. If immediate updates are not possible, administrators should review user access rights to the Zabbix Frontend and monitor for suspicious links leading to the services page containing special symbols (Debian LTS, Zabbix Support).
