CVE-2026-83115: Oracle E-Business Suite Auth Bypass Vulnerability

CVE-2026-83115 Overview

CVE-2026-83115 is a high-severity information disclosure vulnerability in the Oracle Applications Manager component of Oracle E-Business Suite. The flaw resides in the Command Line - RapidClone subcomponent and affects supported versions 12.2.3 through 12.2.15. An unauthenticated remote attacker can exploit the issue over HTTP without any user interaction. Successful exploitation grants unauthorized read access to critical data managed by Oracle Applications Manager, potentially exposing the full set of accessible records. Oracle addressed the issue in Security Alert CSPUSEP2026.

Critical Impact
Unauthenticated network attackers can retrieve confidential data from Oracle Applications Manager through the RapidClone command-line interface without credentials or user interaction.

Affected Products

Oracle E-Business Suite 12.2.3 through 12.2.15
Oracle Applications Manager (Command Line - RapidClone component)
Deployments exposing Oracle Applications Manager over HTTP

Technical Details for CVE-2026-83115

Vulnerability Analysis

The vulnerability affects the RapidClone command-line interface exposed through Oracle Applications Manager. RapidClone automates cloning of Oracle E-Business Suite environments and handles configuration data during clone operations. An attacker with network access to the Applications Manager HTTP interface can trigger the vulnerable code path without authenticating. Exploitation returns confidential data accessible to the Applications Manager context.

The issue only impacts confidentiality. Integrity and availability of the target system remain intact after exploitation. However, the disclosed data can include configuration details, credentials, or business records that enable follow-on attacks against the E-Business Suite stack.

The EPSS score for CVE-2026-83115 is 0.316% at the 24.525 percentile as of 2026-09-16, indicating limited observed exploitation activity at publication.

Root Cause

The root cause is missing authentication and authorization on a RapidClone-related HTTP endpoint within Oracle Applications Manager. Requests that should be restricted to privileged clone operators are processed without validating the caller. This falls under Broken Access Control and Sensitive Data Exposure. Oracle's advisory does not publish source-level details of the flaw.

Attack Vector

The attack vector is network-based over HTTP. An attacker sends a crafted HTTP request to the exposed Oracle Applications Manager interface targeting the RapidClone command path. Because no credentials are required and the attack complexity is low, any host with network reachability to the Applications Manager port can attempt exploitation. Internet-exposed E-Business Suite installations are the highest priority for remediation.

Refer to the Oracle Security Alert CSPUSEP2026 for vendor-provided technical context and fixed versions.

Detection Methods for CVE-2026-83115

Indicators of Compromise

Unauthenticated HTTP or HTTPS requests to Oracle Applications Manager URLs referencing RapidClone endpoints or clone context parameters
Access log entries showing successful 200 responses to RapidClone paths from source IPs that never authenticated
Unexpected outbound data volumes from Oracle E-Business Suite application tier hosts
Requests originating from IP ranges outside normal administrative networks reaching the Applications Manager port

Detection Strategies

Baseline legitimate RapidClone activity and alert on invocations that lack a preceding authenticated session
Deploy web application firewall rules that block or log direct requests to RapidClone command endpoints from non-administrative sources
Correlate Oracle HTTP Server access logs with database audit records to identify anomalous read patterns tied to Applications Manager requests

Monitoring Recommendations

Continuously monitor Oracle E-Business Suite application-tier logs for RapidClone endpoint access outside change windows
Forward Applications Manager and Oracle HTTP Server logs to a central SIEM for retention and correlation
Alert on network flows to Applications Manager originating from untrusted network segments or the public internet

How to Mitigate CVE-2026-83115

Immediate Actions Required

Apply the Oracle Security Alert CSPUSEP2026 patch to all Oracle E-Business Suite 12.2.3 through 12.2.15 environments as the primary remediation
Restrict network access to Oracle Applications Manager so only trusted administrative networks can reach the HTTP interface
Review Applications Manager and web server logs for prior unauthenticated RapidClone requests that may indicate exploitation attempts
Rotate credentials and secrets that may have been exposed through Applications Manager if suspicious access is identified

Patch Information

Oracle released fixes as part of Oracle Security Alert CSPUSEP2026. Administrators should consult the alert for the specific patch numbers applicable to their E-Business Suite 12.2.x release and apply them through the standard Oracle patching workflow. There are no vendor-supplied code-level workarounds that substitute for the patch.

Workarounds

Place Oracle Applications Manager behind a reverse proxy or VPN that enforces authentication before requests reach the application tier
Use network access control lists on load balancers and firewalls to restrict RapidClone endpoints to specific administrative IP addresses
Disable external HTTP exposure of Applications Manager where operationally feasible until the patch is applied

bash

# Example firewall restriction limiting Applications Manager access to an admin subnet
iptables -A INPUT -p tcp --dport 8000 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
