Ireceivables EUVD-2026-47102

Oracle iReceivables within E-Business Suite releases 12.2.3-12.2.15 is vulnerable to unauthenticated remote compromise, enabling complete system takeover and unauthorized access to sensitive receivables data and financial transactions. No vendor patch is currently available; organizations using affected versions face immediate risk to business-critical receivables operations. Urgent network isolation and access controls are required within 24 hours.

Within 24 hours, identify all Oracle EBS systems running releases 12.2.3-12.2.15 and assess network accessibility of the iReceivables module (AR Web Utilities component). Immediately implement firewall rules restricting HTTP/HTTPS access to iReceivables to trusted internal networks only, and document all affected systems. Within 7 days, deploy Web Application Firewall rules to block exploit attempts against the AR Web Utilities component, enable comprehensive access logging with real-time SIEM alerts for anomalous activity, and evaluate operational feasibility of temporary module disablement in non-critical environments. Monitor Oracle's Critical Patch Update channel for patch availability; upon release, establish expedited change management procedures to deploy patches to all production systems within 30 days, after validation in non-production environments.

No vendor-released patch identified at time of analysis. Network segmentation: restrict all iReceivables HTTP/HTTPS access to trusted internal IP addresses via firewall rules; disable any public or internet-facing routing to the module. Web application controls: deploy WAF rules to detect and block malformed requests targeting AR Web Utilities endpoints. Monitoring: enable comprehensive access logging with SIEM integration and real-time alerts for suspicious patterns, authentication failures, or unusual data access. Operational mitigations: evaluate temporary disablement of iReceivables module in non-critical environments to eliminate exposure surface. Vendor engagement: establish direct contact with Oracle Support to obtain patch availability timelines and compatibility information for your specific EBS release versions.
