Vulnerability title: Unrestricted file upload in Livetecs Timelive CVE: CVE-2014-2042 Vendor: Livetecs Product: Timelive Affected version: 6.2.71 Fixed version: 6.5.1 Reported by: Richard Hatch Details: It was discovered that it was possible for low-level TimeLive application users to upload files (by using the "My Projects".."Manage Project" functionality). There was no restriction on file types that could be uploaded and the permissions applied to those uploaded files included "Read and Execute". 1. Using any text editor create a new file "run-cacl.aspx" and add the following content: <%@ Page Language="VB" %> <% System.Diagnostics.Process.Start("calc.exe") %> 2. Login to the TimeLive application as a low-level (standard) user 3. Click "My Projects" from the left-hand menu 4. Click the "Manage" icon - It looks like a notepad and pen 5. Scroll to the bottom of the page that opens and click "Attachment" 6. Click "Browse" and navigate to to where you saved "run-cacl.exe" 7. Click "Upload" 8. Logout of TimeLive [Optional] 9. On the server hosting the TimeLive application run "TaskMgr" 9. Browse to http://MyTimeLiveURL/Uploads/1/1/run-cacl.aspx 10. Observe "calc.exe" running as "NETWORK_SERVICE" in the Task manager Note: Depending on the configuration of the TimeLive application used for testing it may be necessary to change the "1/1" part of the URL.
