Summary
CVE-2026-62624 is a critical vulnerability in the Security and Authentication component of Oracle Reports Developer (part of Oracle Fusion Middleware). It allows an unauthenticated, network-based attacker to compromise the product via the IIOP protocol, with successful exploitation resulting in complete takeover of Oracle Reports Developer. Oracle rates the flaw 9.8 (Critical) under CVSS 3.1 and disclosed it in the August 2026 Critical Security Patch Update.
Technical details
- Root cause: A flaw in the Security and Authentication component of Oracle Reports Developer that fails to properly enforce authentication for requests received over IIOP.
- Trigger conditions: The affected service must be reachable over the network and exposed via the IIOP protocol; no valid credentials or user interaction are needed.
- Attack vector: Network (remote), low attack complexity, no privileges required, no user interaction — described by Oracle as "easily exploitable."
- Impact: Full compromise (takeover) of Oracle Reports Developer, with high impact to confidentiality, integrity, and availability.
Affected software
- Oracle Reports Developer, version 12.2.1.19.0 (Oracle Fusion Middleware)
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the fix provided in Oracle’s August 2026 Critical Security Patch Update (CSPU) for Oracle Reports Developer 12.2.1.19.0. Oracle strongly recommends applying the security patches as soon as possible.
- If patching cannot be performed immediately: Restrict network access to the IIOP listener/port used by Oracle Reports Developer so it is not reachable from untrusted networks (including the internet), and monitor exposed Oracle Reports Developer instances for anomalous IIOP traffic until the patch is applied.
