Description
An XML External Entity (XXE) vulnerability exists in the Ambari/Oozie
project, allowing an attacker to inject malicious XML entities. This
vulnerability occurs due to insecure parsing of XML input using the
`DocumentBuilderFactory` class without disabling external entity
resolution. An attacker can exploit this vulnerability to read arbitrary
files on the server or perform server-side request forgery (SSRF)
attacks. The issue has been fixed in both Ambari 2.7.9 and the trunk
branch.
