New Assault Vectors for CVE-2023-22527
To proactively counter potential threats against Atlassian Confluence instances, we recommend implementing the following additional mitigations:
1. Restrict access to sensitive content through granular permissions and access controls; ensure that only authorized users can view or edit sensitive information.
2. Regularly review and update Confluence plugins and apps to prevent exploitation of outdated software vulnerabilities.
3. Implement multi-factor authentication (MFA) for all user accounts to significantly reduce the risk of unauthorized access.
4. Enable Content Restrictions in the Atlassian Confluence configuration to limit potentially malicious content from being uploaded or shared.
5. Conduct regular security audits and penetration testing to identify and address potential vulnerabilities before attackers can exploit them.
6. Develop a comprehensive incident response plan and conduct regular drills to ensure effective handling of security incidents when they occur.
7. Implement monitoring tools to detect and respond to suspicious activity in real-time, such as unusual login attempts or data exfiltration.
8. Educate Confluence users on proper usage and best practices for handling sensitive information, reducing the risk of human error that could lead to a breach.
9. Utilize firewalls and intrusion detection/prevention systems to block malicious traffic and prevent unauthorized access to your Atlassian Confluence environment.
10. Ensure all software components are up-to-date with the latest security patches and updates, including operating system, browser, and plugins.
11. Regularly review and update the Confluence configuration settings to ensure compliance with organizational security policies and industry best practices.
12. Implement a data backup and disaster recovery plan to minimize the impact of a potential breach or data loss event.
13. Utilize third-party security tools that specialize in detecting and mitigating Atlassian Confluence-specific threats, such as automated vulnerability scanners.
14. Establish an effective threat hunting program to proactively identify and address emerging threats before they can cause harm.
15. Continuously monitor the Atlassian Confluence attack surface by regularly scanning for vulnerabilities, misconfigurations, and potential entry points for attackers.
