# Exploit Author: Jarad Kopf  
# Vendor Homepage: https://www.tableau.com/  
# Software Link: Tableau Desktop downloads: https://www.tableau.com/products/desktop/download  
# Version/Products: See Tableau Advisory: https://community.tableau.com/community/security-bulletins/blog/2019/08/22/important-adv-2019-030-xxe-vulnerability-in-tableau-products  
# Tested on: Windows  
# CVE: CVE-2019-15637  
  
#This comes from https://community.tableau.com/community/security-bulletins/blog/2019/08/22/important-adv-2019-030-xxe-vulnerability-in-tableau-products  
#Severity: High ====== CVSS3 Score: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L - 7.1 High ====== Product Specific Notes: Malicious workbooks, data sources, and extensions files that are published or used on Tableau Server can trigger this vulnerability  
#see also https://github.com/minecrater/exploits/blob/master/TableauXXE.py  
  
#Unfortunately as I did not have access to the source code a lot of this couldn't really be coded.   
#Lot of this seems to be user specific (zoneid, dashboard etc). Virtually just taking the vulnerable request and running the exploit.   
#Very bare bones...wish I could've done more, but maybe someone else with access to the source would want to do that as an exercise.
