SysAid Help Desk Arbitrary File Download

Description

This module exploits two vulnerabilities in SysAid Help Desk that allows an unauthenticated user to download arbitrary files from the system. First, an information disclosure vulnerability (CVE-2015-2997) is used to obtain the file system path, and then we abuse a directory traversal (CVE-2015-2996) to download the file. Note that there are some limitations on Windows, in that the information disclosure vulnerability doesn't work on a Windows platform, and we can only traverse the current drive (if you enter C:\afile.txt and the server is running on D:\ the file will not be downloaded). This module has been tested with SysAid 14.4 on Windows and Linux.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
