What You Need to Be Aware Of
- An unauthenticated Server‑Side Request Forgery (SSRF) vulnerability (CVE‑2025‑61884) in Oracle Configurator is actively being exploited.
- The flaw can allow attackers to reach internal network resources and exfiltrate or modify critical data.
- CISA has added this CVE to its Known Exploited Vulnerabilities catalog and mandates patching by federal agencies by Nov 10, 2025.
How It Might Effect You
- Data Exposure: Attackers can retrieve arbitrary files or invoke internal services, potentially leaking customer or financial data.
- Privilege Escalation: SSRF may be chained with other weaknesses to gain broader system access, enabling ransomware or sabotage.
- Compliance Impact: Failure to patch could violate regulations such as PCI‑DSS, HIPAA, or FedRAMP that require protection of sensitive information.
Mitigation Steps
- Immediate Actions –
- Apply Oracle’s emergency patch for CVE‑2025‑61884 (October 11 update) which validates the

- Apply Oracle’s emergency patch for CVE‑2025‑61884 (October 11 update) which validates the
- Long‑Term Measures –
- Enable network segmentation so internal services are not reachable from the public face of Oracle Configurator.
- Deploy Web Application Firewalls or mod_security rules to block SSRF patterns if patching is delayed.
- Conduct a security assessment of all Oracle E‑Business Suite instances to confirm no other unpatched flaws (e.g., CVE‑2025‑61882) remain.
