CVE-2026-83157

CVE-2026-83157 is a difficult-to-exploit vulnerability in the Command Line - RapidClone component of Oracle Applications Manager, part of Oracle E-Business Suite releases 12.2.3 through 12.2.15. It is triggered over the network via HTTP by an attacker who already holds high privileges, and a successful attack results in a complete takeover of Oracle Applications Manager. Because the vulnerability has a scope change, successful attacks may also significantly impact additional products beyond Applications Manager, with high impacts to confidentiality, integrity, and availability (CVSS 3.1 base score 8.0). Any organization running E-Business Suite 12.2.3-12.2.15 with Applications Manager exposed over HTTP to privileged users is affected. There is no known public proof of concept, it does not appear in the CISA Known Exploited Vulnerabilities catalog, and no exploitation in the wild has been reported.

What to do: Apply the Oracle Critical Patch Update that addresses CVE-2026-83157 to all E-Business Suite 12.2.3-12.2.15 environments as soon as your patching cycle allows. Restrict HTTP access to Oracle Applications Manager and RapidClone command-line functionality to trusted administrative networks and accounts, since exploitation requires high privileges. Review EBS audit and concurrent-manager logs for unexpected RapidClone or cloning activity by privileged accounts, and enforce least-privilege separation for administrators who do not need Applications Manager access.
