What is the Vulnerability?

CVE-2025-61882 is a critical (CVSS 9.8) unauthenticated remote code execution vulnerability in the BI Publisher integration of Oracle E-Business Suite’s Concurrent Processing component. The flaw is remotely exploitable over HTTP without authentication, allowing attackers to execute arbitrary code and fully compromise affected systems.

This vulnerability has been actively exploited as a zero-day in data theft and extortion campaigns, with activity linked to the Cl0p ransomware group. Successful exploitation enables complete takeover of Oracle Concurrent Processing, opening the door to lateral movement, sensitive data exfiltration, and potential ransomware deployment.

Oracle has released an out-of-band security patch and IoCs to address the issue. Immediate patching or compensating controls are strongly recommended for all vulnerable EBS deployments.

What is the recommended Mitigation?
