CVE-2025-61882

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%.

What to 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.
