+--------------------------------------------------------------------------------------------------------------------------------+ # Exploit Title : ManageEngine Support Center Plus <=7908 Multiple Vulnerabilities # Date: 06-03-2012 # Author: xistence (xistence<[AT]>0x90.nl) # Software link : http://www.manageengine.com/products/support-center/64045241/ManageEngine_SupportCenter_Plus_7_9_0_SP-0_8_0.ppm # Vendor site : http://www.manageengine.com/ # Version : 7908 and lower # Tested on : CentOS 5.x +--------------------------------------------------------------------------------------------------------------------------------+ 1) Arbitrary File Upload (File Extension Verification Bypass) It's possible to bypass the image extension check in the ticket creation editor. Normally you would go to Requests -> New Request -> select the "Insert Image" to upload a picture to be included in the ticket and is restricted to jpg/gif/png files. If you send a POST request directly to the /jsp/UploadImage.jsp?Module=Workorder url you'll be able to upload any file. This might lead to uploading web site files which could be used for malicious actions (backdoors/shells). Below a sample POST request, note that a valid cookie is needed (and be authenticated) to perform these actions. The POST request uploads a file test.txt with the contents "TEST!"
