Apache Ambari: Remote Code Injection in Ambari Metrics and AMS Alerts

A remote code injection vulnerability exists in the Ambari Metrics and
AMS Alerts feature, allowing authenticated users to inject and execute
arbitrary code. The vulnerability occurs when processing alert
definitions, where malicious input can be injected into the alert script
execution path. An attacker with authenticated access can exploit this
vulnerability to execute arbitrary commands on the server. The issue has
been fixed in the latest versions of Ambari.
