Vulnerability Information

Severity: Critical
Vulnerability Published: 2013-11-18
Patch Published: 2013-10-30
CVE [?]: CVE-2013-7390
CPE [?]: cpe:/a:zohocorp:manageengine_desktop_central

Synopsis

The remote web server contains a Java web application that allows for arbitrary file uploads.

Description

The version of ManageEngine Desktop Central installed on the remote host is affected by an arbitrary file upload vulnerability due to the 'AgentLogUploadServlet' script not properly sanitizing user-supplied input to the 'filename' parameter. A remote, unauthenticated attacker can exploit this issue to upload files containing arbitrary code and then execute them on the remote host with NT-AUTHORITY\SYSTEM privileges.

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

Solution

Upgrade to ManageEngine Desktop Central 8.0.0 build 80293 or later.
