CVE Alert: CVE-2025-61882 – Oracle Corporation – Oracle Concurrent Processing

Risk verdict

Active exploitation of a remote, unauthenticated access to the BI Publisher Integration component is being observed; treat as priority 1.

Why this matters

An attacker can compromise the Oracle Concurrent Processing without credentials via HTTP, enabling complete takeover of the affected component and broad impact across Oracle E-Business Suite processes. This jeopardises confidentiality, integrity and availability, potentially driving data exfiltration, business-process disruption and ripple effects across downstream systems.

Most likely attack path

Exploitation requires no user interaction and relies on network access to the HTTP endpoint. An unauthenticated attacker can gain control directly, with potential rapid lateral movement to related processing services or the Oracle database within the EBS environment, given the unchanged scope and high-impact CVSS metrics.

Who is most exposed

Organizations deploying Oracle E-Business Suite with BI Publisher Integration, particularly where HTTP access is exposed to the network (on‑prem or cloud), are at greatest risk. Environments without timely patching or with broad internet exposure are especially vulnerable.

Detection ideas

• Unauthenticated HTTP requests targeting the BI Publisher Integration endpoints.
• Sudden spikes in external traffic or repeated access attempts from unusual/unknown IPs.
• Unexpected or new Oracle Concurrent Processing/BI Publisher processes appearing outside normal maintenance windows.
• Anomalous BI Publisher job or concurrent manager activity.
• Web server logs showing patterns consistent with pre-auth exploitation attempts.

Mitigation and prioritisation

• Apply the vendor advisory to patch 12.2.3–12.2.14; prioritise immediate remediation.
• Restrict HTTP exposure: implement allowlists, disable anonymous access where possible, and enforce strong network segmentation or WAF rules.
• Deploy compensating controls: immediate monitoring/alerting on BI Publisher endpoints; enhanced logging; restrict lateral movement via network controls.
• Schedule and validate patch deployment in a controlled change window; test in a staging environment first; ensure clean backups before patching.
• Reassess access to Oracle Concurrent Processing post-patch and conduct targeted security testing.
