Another remotely exploitable Oracle EBS vulnerability requires your attention (CVE-2025-61884)

CVE-2025-61882 is a critical (CVSS 9.8) authentication flaw (CWE-287) in the BI Publisher Integration component of the Oracle Concurrent Processing product within Oracle E-Business Suite. An unauthenticated attacker with network access over HTTP can exploit it remotely with no credentials and no user interaction, achieving a takeover of Oracle Concurrent Processing with high confidentiality, integrity, and availability impact. Any organization running Oracle E-Business Suite 12.2.3 through 12.2.14 is affected, especially instances reachable from the internet. The flaw is being actively exploited in the wild: the Cl0p data-theft group has used it to breach dozens of organizations (including Harvard University, with 1.3 TB of data leaked), CISA added it to the Known Exploited Vulnerabilities catalog on 2025-10-06 with known ransomware use, and EPSS puts its 30-day exploitation probability at 99.7%.

Do: Apply Oracle's released patch or mitigations for CVE-2025-61882 to affected E-Business Suite 12.2.3-12.2.14 deployments as instructed by the vendor; per CISA KEV requirements, federal agencies must follow BOD 22-01 guidance or discontinue use if mitigations are unavailable. Until patched, limit internet exposure of EBS and its BI Publisher/Concurrent Processing HTTP endpoints, and review web and application logs for unauthenticated access and signs of Cl0p-style data theft or follow-on ransomware.

Oracle Configurator, a component of Oracle E-Business Suite, is affected by a server-side request forgery (SSRF) flaw in its Runtime UI component (CVE-2025-61884). The flaw is easily exploitable: an unauthenticated attacker with network access over HTTP can trigger the server to make attacker-controlled requests, compromising Oracle Configurator and gaining unauthorized access to critical data or complete access to all data accessible to Oracle Configurator. The CVSS 3.1 score is 7.5 (high) with confidentiality-only impact, meaning the flaw primarily exposes sensitive data rather than altering or destroying it. All supported Oracle E-Business Suite 12.2.x releases from 12.2.3 through 12.2.14 are affected, and Oracle has issued an emergency security update in response. Exploitation is confirmed in the wild: the flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2025-10-20 with known ransomware use, and EPSS assigns a 97.8% probability of exploitation in the next 30 days (100th percentile).

Do: Apply the fixes from Oracle's emergency security update for CVE-2025-61884 across all E-Business Suite 12.2.3-12.2.14 environments, prioritizing internet-exposed instances; U.S. federal agencies must remediate per BOD 22-01 or follow applicable cloud-service guidance by the KEV due date. Until patched, restrict untrusted network access to the Configurator Runtime UI (HTTP) and monitor EBS logs and outbound server-side requests for signs of exploitation. Given the confirmed ransomware association, hunt for follow-on activity such as unusual data access or lateral movement originating from EBS servers.
