Versions Affected:

Kylin 2.0.0, 2.1.0, 2.2.0, 2.3.0, 2.3.1, 2.3.2, 2.4.0, 2.4.1, 2.5.0, 2.5.1, 2.5.2, 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 
2.6.5, 2.6.6, 3.0.0-alpha, 3.0.0-alpha2, 3.0.0-beta, 3.0.0, 3.0.1, 3.0.2, 3.1.0, 4.0.0-alpha.

Description:

Kylin has one restful api which exposed Kylin's configuration information without any authentication, so it is 
dangerous because some confidential information entries will be disclosed to everyone.

Mitigation:

Users could edit "$KYLIN_HOME/WEB-INF/classes/kylinSecurity.xml", and remove this line "&lt;scr:intercept-url 
pattern="/api/admin/config" access="permitAll"/&gt;". After that,  restart all Kylin instances to make it effective.

Otherwise, you can upgrade Kylin to 3.1.1.
