More information:

Multiple vulnerabilities were discovered in Zabbix, a network monitoring solution. An attacker may enumerate valid users and redirect to external links through the zabbix web frontend.

  • CVE-2019-15132

    Zabbix allows User Enumeration. With login requests, it is possible to enumerate application usernames based on the variability of server responses (e.g., the Login name or password is incorrect and No permissions for system access messages, or just blocking for a number of seconds). This affects both api_jsonrpc.php and index.php.

  • CVE-2020-15803

    Zabbix allows stored XSS in the URL Widget. This fix was mistakenly dropped in previous upload 1:3.0.31+dfsg-0+deb9u1.

This update also includes several other bug fixes and improvements. For more information please refer to the upstream changelog file.

For Debian 9 stretch, these problems have been fixed in version 1:3.0.32+dfsg-0+deb9u1.

We recommend that you upgrade your zabbix packages.
