Zabbix < 1.8.6 Multiple Vulnerabilities

medium Nessus Plugin ID 56091

Synopsis

The remote web application may be affected by multiple vulnerabilities.

Description

According to its self-reported version number, the instance of Zabbix listening on the remote host is earlier than 1.8.6. It could, therefore, be affected by multiple vulnerabilities.

- An input validation error exists in the script 'acknow.php' that allows arbitrary script or HTML injection via the 'backurl' parameter. (CVE-2011-2904)

- An error exists related to 'zabbix_agentd' and 'vfs.file.cksum'. An attacker could cause excessive CPU usage if the 'vfs.file.cksum' command is pointed at a special device such as '/dev/urandom'. (CVE-2011-3263)

- An information disclosure vulnerability exists in the script 'popup.php' because the 'srcfld2' parameter is not properly checked. This vulnerability can reveal sensitive information such as the application's install path. (CVE-2011-3264)

Note that Nessus has not tested for these flaws but has instead relied on the version in the Zabbix login page.

Solution

Update Zabbix to version 1.8.6 or later.
