Version        : 1:3.0.32+dfsg-0+deb9u1
CVE ID         : CVE-2019-15132 CVE-2020-15803
Debian Bug     : 935027 966146

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.

For the detailed security status of zabbix please refer to
its security tracker page at:
