Web based interface for xinet asset management solution.


[Vulnerability Type]
Pre-Auth SQL Injection


[CVE Reference]
CVE-2019-19245


[Security Issue]
NAPC Xinet (interface) Elegant 6 Asset Library v6.1.655 allows Pre-Authentication Error based SQL Injection via the /elegant6/login LoginForm[username] field when
double quotes are used. The vulnerable version seems to be old, but it may still be possible to still find it deployed as I have.

Vulnerable Parameter: LoginForm[username] (POST) Method.
