Horde Help Viewer Arbitrary Code Execution

high Nessus Plugin ID 21164


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote web server contains a PHP application that allows execution of arbitrary PHP code.


The version of Horde installed on the remote host fails to sanitize user-supplied input before using it in the Help viewer to evaluate code. An unauthenticated attacker could exploit this flaw to execute arbitrary command on the remote host subject to the privileges of the web server user id.


Upgrade to Horde 3.0.10 / 3.1.1 or later.
