Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Restrict network access to Oracle Business Intelligence Enterprise Edition HTTP service: configure firewall or network ACLs to allow inbound HTTP/HTTPS to the Oracle BI EE servers only from trusted management IP addresses or through a VPN. Block direct public HTTP access from untrusted networks.
- Compensating control
Deploy WAF or web-server rules to block malicious requests targeting the getPreviewImage endpoint and its FilePath parameter: create rules that block requests containing the getPreviewImage path and/or FilePath parameter values that include path traversal patterns (e.g., '..' sequences) or non-expected file paths, and validate/normalize the FilePath parameter before passing to the application.
