AI-suggested

1. Upgrade ZenTao installations immediately to version 21.7.6 or later to apply the official patch addressing the SSRF vulnerability. 2. Implement strict egress filtering on servers running ZenTao to restrict outbound HTTP/HTTPS requests only to trusted destinations, minimizing SSRF exploitation scope. 3. Employ network segmentation to isolate application servers from sensitive internal services and metadata endpoints. 4. Monitor application logs and network traffic for unusual outbound requests originating from ZenTao servers, which may indicate exploitation attempts. 5. Conduct regular security assessments and penetration tests focusing on SSRF and related vulnerabilities in web applications. 6. Educate development and operations teams about SSRF risks and secure coding practices to prevent similar issues in custom integrations or plugins.
