EMERGENCY PATCH NOW: Oracle RCE (CVE-2025-61882) is Being Actively Exploited in the Wild

EMERGENCY PATCH: Oracle E-Business Suite RCE (CVE-2025-61882)

Critical unauthenticated RCE actively exploited in the wild — patch immediately, hunt everywhere.

TL;DR

Oracle E-Business Suite has a critical unauthenticated RCE, **CVE-2025-61882** (CVSS 9.8). Oracle has released an emergency patch — apply it now.
Threat actors — attributed to Cl0p/related extortion groups by multiple vendors — have exploited this in the wild and used stolen data for extortion campaigns.
Exploit code and indicators have been leaked; unpatched Internet-facing EBS instances are at high risk of compromise.
Immediate action: patch from Oracle My Oracle Support, block exposed EBS interfaces at the network edge, hunt for the IOCs in your estate, and assume breach if you have internet-facing EBS.

What happened — short summary (verified sources)

Oracle released a security alert for CVE-2025-61882 — a critical, unauthenticated remote code execution vulnerability in the Oracle Concurrent Processing / BI Publisher integration component of Oracle E-Business Suite (affects supported versions 12.2.3–12.2.14). Oracle states the flaw is exploitable via HTTP and can lead to full takeover of the Oracle Concurrent Processing component.

Multiple threat-intelligence vendors and cloud defenders (Google Cloud Threat Intelligence, CrowdStrike, Rapid7, etc.) have observed active exploitation and campaigns tied to financially motivated extortion actors (Cl0p/FIN11 variants). Vendors warn that exploit scripts and related IOCs have been circulated, increasing the risk of broad exploitation.

Immediate prioritized actions — do these now (order matters)

Apply Oracle’s emergency patch(s) immediately: Download and install the fixes from the Oracle Security Alert (My Oracle Support). Prioritize internet-facing and DMZ-reachable EBS instances first.
Isolate & block exposure: If you cannot patch immediately, block HTTP access to Oracle EBS from untrusted networks (edge firewall, WAF rules, network ACLs). Prefer deny-by-default and only allow trusted management subnets.
Hunt for IOCs and suspicious activity: pull vendor IOCs and hunt for indicators (file hashes, IPs, suspicious commands, unusual concurrent processing jobs). Check Oracle’s advisory and vendor blog posts for published IOCs.
Assume breach & preserve evidence: if you find indicators, isolate affected hosts, preserve memory and disk images, enable full packet capture where feasible, and engage IR. Vendors recommend immediate forensic capture and vendor SIRT contact.
Rotate credentials & secrets used by EBS: rotate service accounts, API keys, database credentials and any admin accounts that could be abused from the affected EBS instances.
Search for data exfil artifacts: look for unusual archive exports, DB dumps, or outbound transfers; attackers in observed campaigns used stolen DB exports as extortion leverage.

Hunt checklist & high-signal queries (copy/paste)

Adapt these to your EDR/SIEM logging schema and log retention windows. These are defensive patterns (no exploit mechanics).

HTTP access to BI Publisher / Concurrent Processing endpoints from external IPs — list recent unique source IPs and correlate by ASN/geography.
New/modified scheduled concurrent jobs or unexpected file export jobs (DB extract or BI report exports). Correlate with admin user changes.
Unexpected processes or web shells on EBS application hosts (look for unknown interpreters, web root uploads, obscure scripts).
Outbound network connections to domains/IPs listed in vendor IOCs or to suspicious cloud storage / paste services within minutes/hours after EBS activity.
Account activity anomalies — new admin accounts, password changes, or MFA enrollment changes for EBS admins.

Known Indicators (publicly reported) — check vendor advisories for the most up-to-date list

Vendors have published lists of IOCs (sample IPs, file hashes, suspicious commands) in their advisories and writeups. Do not treat this list as exhaustive — consult Oracle, Rapid7, CrowdStrike and Google Cloud Threat Intelligence for the canonical, updated IOCs before acting.

Where to get vendor IOCs and advisories — Oracle Security Alert (official patch & advisory), Google Cloud Threat Intelligence blog, Rapid7 ETR post, CrowdStrike blog.

What NOT to do

Do not search for or run leaked exploit scripts in your environment — they may be unsafe and will likely trigger destructive behaviors.
Do not publicly post exploit code or PoCs — that increases risk to other organizations and may be illegal in some jurisdictions.

If you are already compromised — recommended escalation

Isolate affected hosts from networks (air-gap if possible).
Preserve forensic evidence (memory image, file system, database snapshots) and do not reboot unless required for preservation guidance.
Engage your incident response partner, vendor SIRT, and law enforcement as appropriate; several vendors have shared contacts for victims in recent campaigns. Notify affected stakeholders and follow regulatory breach notification requirements in your jurisdiction.
