Server-Side Request Forgery (SSRF) vulnerability in Apache Kylin. Through a kylin server, an attacker may forge a request to invoke "/kylin/api/xxx/diag" api on another internal host and possibly get leaked information. There are two preconditions: 1) The attacker has got admin access to a kylin server; 2) Another internal host has the "/kylin/api/xxx/diag" api
endpoint open for service.
This issue affects Apache Kylin: from 5.0.0 through
5.0.1.
Users are recommended to upgrade to version 5.0.2, which fixes the issue.
