CVE-2026-46932: Oracle EAM Auth Bypass Vulnerability

CVE-2026-46932 Overview

CVE-2026-46932 is an access control weakness in the Internal Operations component of Oracle Enterprise Asset Management, part of Oracle E-Business Suite. The flaw affects supported versions 12.2.3 through 12.2.15. An authenticated attacker with low privileges can exploit the issue over HTTP without user interaction. Successful exploitation grants unauthorized access to all data accessible by Oracle Enterprise Asset Management and enables a partial denial of service. Oracle disclosed the issue in the Oracle Security Alert Advisory - CVE-2026-46932. The weakness is categorized under [CWE-284: Improper Access Control].

Critical Impact
A low-privileged network attacker can read all data accessible by Oracle Enterprise Asset Management and trigger partial service disruption with no user interaction.

Affected Products

Oracle E-Business Suite — Enterprise Asset Management 12.2.3
Oracle E-Business Suite — Enterprise Asset Management versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-46932

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Enterprise Asset Management. The affected code path fails to enforce proper authorization checks before granting access to protected data and operations. A network-reachable attacker holding any low-privileged Oracle E-Business Suite account can interact with the exposed HTTP interface and bypass access restrictions. The Internal Operations component is typically used to manage maintenance work orders, asset hierarchies, and operational metadata, so unauthorized access exposes business-critical asset and maintenance information. Because the scope is unchanged, the impact remains within the Enterprise Asset Management component itself, but every record reachable by that component becomes available to the attacker. Oracle rates the confidentiality impact as high and availability impact as low, with no integrity impact.

Root Cause

The root cause is improper access control [CWE-284]. The Internal Operations component does not validate that the authenticated principal holds the required authorization before returning protected data or invoking sensitive operations. Authentication is required, but the privilege barrier is set low, so any legitimate application user can reach the affected code path.

Attack Vector

Exploitation requires only network access over HTTP and a valid low-privileged Oracle E-Business Suite account. Attack complexity is low, no user interaction is needed, and no specialized tooling is required to issue the crafted requests against the exposed endpoint. No public proof-of-concept exploit is currently available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

No verified exploitation code is publicly available. See the Oracle Security Alert Advisory for vendor-provided technical context.

Detection Methods for CVE-2026-46932

Indicators of Compromise

Anomalous HTTP requests from low-privileged user sessions targeting Enterprise Asset Management Internal Operations URLs.
Spikes in data retrieval volume or unusual export activity tied to non-administrative EAM user accounts.
Repeated authorization-related errors followed by successful responses from the same session, indicating probing of access checks.

Detection Strategies

Enable Oracle E-Business Suite application auditing for the Enterprise Asset Management module and review access to Internal Operations functions.
Correlate web tier access logs with application user identities to flag low-privileged accounts touching restricted EAM endpoints.
Baseline expected EAM Internal Operations traffic per user role and alert on deviations such as off-hours access or access from unusual source IPs.

Monitoring Recommendations

Forward Oracle E-Business Suite middle-tier logs and database audit records into a centralized SIEM for correlation.
Monitor authentication and session activity for shared or service accounts that interact with the EAM module.
Track outbound network egress from the EAM application server to detect attempts to exfiltrate harvested asset data.

How to Mitigate CVE-2026-46932

Immediate Actions Required

Apply the patch from the June 2026 Oracle Critical Patch Update Security Alert to all Oracle E-Business Suite instances running affected versions of Enterprise Asset Management.
Inventory all Oracle E-Business Suite environments, including non-production, to identify versions 12.2.3 through 12.2.15.
Restrict network reachability to the E-Business Suite HTTP interface using firewalls, VPN, or reverse proxy access controls until patching is complete.
Audit Oracle E-Business Suite user accounts and remove or disable unused low-privileged accounts that could be abused to authenticate against the vulnerable endpoint.

Patch Information

Oracle released a fix as part of the June 2026 Critical Patch Update. Customers must consult the Oracle Security Alert Advisory and apply the corresponding patch for Oracle E-Business Suite versions 12.2.3 through 12.2.15. Oracle states that unsupported versions are likely affected and should be upgraded to a supported, patched release.

Workarounds

No vendor-supplied workaround replaces patching; restrict access to the Enterprise Asset Management module via responsibility and menu assignments where feasible.
Place the E-Business Suite front end behind a web application firewall and apply rules that block anomalous request patterns to EAM Internal Operations URLs.
Enforce least privilege by reviewing EAM responsibilities and removing access for users who do not require Internal Operations functions.

bash

# Example: restrict HTTP access to the Oracle E-Business Suite tier
# Allow only trusted management subnets until patching is complete
iptables -A INPUT -p tcp --dport 8000 -s 10.10.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
