A code injection vulnerability exists in the Ambari Alert Definition feature, allowing authenticated users to inject and execute arbitrary shell commands. The vulnerability arises when defining alert scripts, where the script filename field is executed using `sh -c`. An attacker with authenticated access can exploit this vulnerability to inject malicious commands, leading to remote code execution on the server. The issue has been fixed in the latest versions of Ambari.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
