Debian DLA-2631-1 : zabbix security update

medium Nessus Plugin ID 148926

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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:

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
