Exploitation Attempts Against Critical Oracle E‑Business Suite SQL Injection (CVE‑2026‑101767)
What It Is — An unauthenticated SQL injection in the Thin Client Framework servlet of Oracle E‑Business Suite (EBS) Application Object Library (versions 12.2.3‑12.2.15) was disclosed as CVE‑2026‑101767. The flaw allows an attacker to execute arbitrary SQL as the APPS database user and, subsequently, run commands on the application host, exposing financial, payroll, HR, and procurement data. It carries a CVSS 9.8 (Critical). Oracle released a patch on 20 Oct 2026, but on 27 Oct 2026 researchers observed active exploitation attempts against Internet‑facing instances that had not yet applied the fix. Indicators of compromise (IOCs) have been published, and guidance recommends removing the vulnerable servlet from allowlists and restricting web‑tier access.
Affected Products — Oracle E‑Business Suite (EBS) Application Object Library, versions 12.2.3 through 12.2.15.
Why It Matters for Trust & Control Assurance — The episode underscores the need for a robust vulnerability‑management control that proves timely patch application and continuous verification of remediation.

Recommended Actions
- Confirm that every Oracle EBS host has installed the October 2026 patch for CVE‑2026‑101767.
- Remove the
/OA_HTML/AppsTCFServerservlet from any web‑tier allowlists and limit access to trusted network ranges. - Run the published IOCs against your environment and retain the scan results as audit evidence.
- Document the patch‑deployment process and maintain a continuous‑monitoring feed for unpatched assets.
