Zabbix before 1.8.6 allows remote attackers to obtain sensitive information via an invalid srcfld2 parameter to popup.php, which reveals the installation path in an error message.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2011-372:01 advisory.

    ZABBIX is software that monitors numerous parameters of a network and the health and integrity of servers.
    ZABBIX uses a flexible notification mechanism that allows users to configure e-mail based alerts for     virtually any event. This allows a fast reaction to server problems. ZABBIX offers excellent reporting and     data visualisation features based on the stored data. This makes ZABBIX ideal for capacity planning.
    ZABBIX supports both polling and trapping. All ZABBIX reports and statistics, as well as configuration     parameters are accessed through a web-based front end. A web-based front end ensures that the status of     your network and the health of your servers can be assessed from any location. Properly configured, ZABBIX     can play an important role in monitoring IT infrastructure. This is equally true for small organisations     with a few servers and for large companies with a multitude of servers.
    Security issues fixed with this release:
    CVE-2011-3263     zabbix_agentd in Zabbix before 1.8.6 and 1.9.x before 1.9.4 allows context-dependent attackers to cause a     denial of service (CPU consumption) by executing the vfs.file.cksum command for a special device, as     demonstrated by the /dev/urandom device.
    CVE-2011-3264     Zabbix before 1.8.6 allows remote attackers to obtain sensitive information via an invalid srcfld2     parameter to popup.php, which reveals the installation path in an error message.
    CVE-2011-3265     popup.php in Zabbix before 1.8.7 allows remote attackers to read the contents of arbitrary database tables     via a modified srctbl parameter.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.

- update to 1.8.6
