Jira - Remote Code Execution (CVE-2019-11581)

Jira is affected by a Remote Code Execution vulnerability in the Jira Server and Data Center, inside the Contact Administrators action. This means that the SMTP server is configured in Jira, and the Contact Administrators Form option is enabled. This may potentially cause remote code execution, allowing a malicious unauthenticated attacker to execute arbitrary code on the server.

The risk exists that a remote unauthenticated attacker can fully compromise the Jira Server to steal confidential information, install ransomware, or pivot to the internal network.

Upgrade the Atlassian Jira to the latest version.
