Several security vulnerabilities have been discovered in zabbix, a network monitoring solution, potentially allowing an attacker to perform a stored XSS, Server-Side Request Forgery (SSRF), exposure of sensitive information, a system crash, or arbitrary code execution.

CVE-2023-32721

A stored XSS has been found in the Zabbix web application in the Maps element if a URL field is set with spaces before URL.

CVE-2023-32723

Inefficient user permission check, as request to LDAP is sent before user permissions are checked.

CVE-2023-32726

Possible buffer overread from reading DNS responses.

For Debian 10 buster, these problems have been fixed in version 1:4.0.4+dfsg-1+deb10u4.

We recommend that you upgrade your zabbix packages.
