EMC ViPR SRM Cross Site Request Forgery

------------------------------------------------------------------------
EMC M&R (Watch4net) lacks Cross-Site Request Forgery protection
------------------------------------------------------------------------
Han Sahin, November 2014

------------------------------------------------------------------------
Abstract
------------------------------------------------------------------------
It was discovered that EMC M&R (Watch4net) does not protect against
Cross-Site Request Forgery (CSRF) attacks. A successful CSRF attack can
compromise end user data and may allow an attacker to perform an account
hijack. If the targeted end user is the administrator account, this
results in a full compromise of Watch4net.

------------------------------------------------------------------------
Affected versions
------------------------------------------------------------------------
Versions of EMC ViPR SRM prior to version 3.7 are affected by these
vulnerabilities.

Fix
------------------------------------------------------------------------
EMC released 34247_ViPR-SRM to fix these vulnerabilities. Please
note that this fix is only available for registered EMC Online Support
customers.

The following proof of concept will create a new user named CSRF with password set to 1 in Watch4net - provided that the victim is logged in with an administrator account.
