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.

For the detailed security status of zabbix please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
