CVE-2026-70708: Oracle Sales Foundation Auth Bypass Flaw

CVE-2026-70708 Overview

CVE-2026-70708 is a high-severity vulnerability in the Oracle Sales Foundation product of Oracle E-Business Suite, specifically within the Security API component. The flaw affects supported versions 12.2.3 through 12.2.15. An authenticated attacker with low privileges and network access via HTTP can compromise Oracle Sales Foundation. Successful exploitation allows unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to all Oracle Sales Foundation accessible data. Oracle disclosed the issue in the Oracle Security Alert.

Critical Impact
Authenticated network attackers can read, modify, or delete critical data stored within Oracle Sales Foundation.

Technical Details for CVE-2026-70708

Vulnerability Analysis

The vulnerability resides in the Security API component of Oracle Sales Foundation, a module within Oracle E-Business Suite. The flaw permits an authenticated attacker holding low-privilege credentials to bypass intended access restrictions over HTTP. Once exploited, the attacker gains full read access and write access to data accessible by the Sales Foundation application. The confidentiality and integrity impacts are both rated High, while availability is not affected. This scope indicates the flaw enables data tampering and disclosure rather than service disruption, which is consistent with a broken access control or authorization defect within the Security API layer.

Root Cause

Oracle's advisory identifies the affected component as the Security API of Oracle Sales Foundation. The vulnerability class aligns with improper enforcement of authorization checks. A low-privileged session can invoke API operations that should be restricted to higher-privileged roles. Oracle has not published deeper technical details beyond the advisory metadata.

Attack Vector

Exploitation requires network reachability to the Oracle E-Business Suite HTTP endpoints and valid low-privilege credentials. No user interaction is required. The attack complexity is low, meaning no special conditions must be met beyond authenticating and issuing crafted HTTP requests to the Sales Foundation Security API. The EPSS score is 0.365% (percentile 29.8) as of 2026-08-20, indicating low observed exploitation activity at time of publication.

No public proof-of-concept code is available. Refer to the Oracle Security Alert for vendor-supplied technical guidance.

Detection Methods for CVE-2026-70708

Indicators of Compromise

Unexpected HTTP requests from low-privilege user accounts targeting Oracle Sales Foundation Security API endpoints under the E-Business Suite web tier.
Unauthorized create, update, or delete operations against Sales Foundation database tables recorded in Oracle audit logs.
Anomalous session activity from Sales Foundation user accounts accessing records outside their assigned responsibility or organization scope.

Detection Strategies

Enable and monitor Oracle E-Business Suite Sign-On Audit and Page Access Tracking to record which users invoke Security API functions.
Correlate application-tier access logs with database audit records to identify privilege boundary violations by low-privilege accounts.
Baseline normal API call patterns per role and alert on deviations, particularly bulk data reads or writes originating from non-administrative users.

Monitoring Recommendations

Forward Oracle E-Business Suite web tier, concurrent manager, and database audit logs to a centralized SIEM for correlation and long-term retention.
Alert on repeated HTTP 4xx and 5xx responses from Sales Foundation endpoints, which may indicate enumeration or authorization probing.
Review Oracle FND user activity for accounts assigned minimal responsibilities that begin accessing sensitive Sales Foundation modules.

How to Mitigate CVE-2026-70708

Immediate Actions Required

Apply the patches referenced in the Oracle Security Alert for August 2026 to all Oracle E-Business Suite environments running Oracle Sales Foundation versions 12.2.3 through 12.2.15.
Inventory all internet-exposed Oracle E-Business Suite instances and restrict external access to the Sales Foundation module until patching completes.
Review Oracle FND user and responsibility assignments to remove unused or over-privileged low-tier accounts that could serve as an exploitation foothold.

Patch Information

Oracle addressed CVE-2026-70708 in the August 2026 Critical Security Patch Update. Consult the Oracle Security Alert for patch identifiers, download locations, and version-specific installation guidance. Apply the patch to each affected 12.2.x release level.

Workarounds

Restrict HTTP access to Oracle Sales Foundation endpoints using network segmentation, reverse proxy allow-lists, or web application firewall rules until the patch is deployed.
Rotate credentials for low-privilege Sales Foundation accounts and enforce multi-factor authentication at the E-Business Suite login layer.
Disable inactive user accounts and unused responsibilities within Oracle Sales Foundation to reduce the pool of accounts an attacker could leverage.
