Severity:
=========
Medium


Details:
========
Multiple persistent input validation vulnerabilities are detected on eFronts Community++ application v3.6.10.
The vulnerability allows an remote attacker or local low privileged user account to inject/implement malicious 
persistent script code. Successful exploitation with low required user inter action can result in session hijacking 
or persistent context manipulations.
