Description Preview

The DefaultOSWorkflowConfigurator class in Jira Server and Jira Data Center before version 8.18.1 contains a Remote Code Execution (RCE) vulnerability. Remote attackers who can trick a system administrator into importing a malicious workflow can execute arbitrary code on the system. The vulnerability stems from the ability to use various problematic OSWorkflow classes as part of workflows, which can be exploited for code execution.

Overview

This vulnerability (CVE-2017-18113) affects the DefaultOSWorkflowConfigurator class in Jira Server and Jira Data Center versions prior to 8.18.1. It is classified as CWE-94 (Code Injection). The issue allows attackers to execute arbitrary code by crafting malicious workflow configurations that leverage unsafe conditions, validators, functions, and registers built into the OSWorkflow library and other Jira dependencies. The attack requires social engineering to convince a system administrator to import the malicious workflow. Once imported, the attacker can achieve remote code execution on the affected system.

Remediation

To remediate this vulnerability:

  1. Upgrade Jira Server or Jira Data Center to version 8.18.1 or later.
  2. If immediate upgrade is not possible, implement strict controls over workflow imports:
    • Only allow trusted administrators to import workflows
    • Carefully review all workflow imports before applying them
    • Consider implementing network segmentation to limit the impact of a potential compromise
  3. Monitor system logs for suspicious activities related to workflow imports or configurations
  4. Implement the principle of least privilege for all Jira administrators
