Résumé
Apache Ambari: authenticated users could perform XXE to read arbitrary files on the server
Description d'origine
La description telle que publiée par la source (souvent en anglais).
XML External Entity injection in apache ambari versions <= 2.7.7, Users are recommended to upgrade to version 2.7.8, which fixes this issue.
More Details:
Oozie Workflow Scheduler had a vulnerability that allowed for root-level file reading and privilege escalation from low-privilege users. The vulnerability was caused through lack of proper user input validation.
This vulnerability is known as an XML External Entity (XXE) injection attack. Attackers can exploit XXE vulnerabilities to read arbitrary files on the server, including sensitive system files. In theory, it might be possible to use this to escalate privileges.
