CVE-2026-62525: Oracle Quality Auth Bypass Vulnerability

CVE-2026-62525 Overview

CVE-2026-62525 is a vulnerability in the Oracle Quality product of Oracle E-Business Suite (EBS), specifically within the Quality Workbench HTML system component. Supported versions 12.2.3 through 12.2.15 are affected. The flaw allows a low-privileged attacker with network access over HTTP to compromise Oracle Quality. Successful exploitation grants unauthorized update, insert, or delete access to a subset of Oracle Quality data, unauthorized read access to a subset of that data, and the ability to cause a partial denial of service. The weakness is categorized under [CWE-200] Information Exposure.

Critical Impact
Authenticated network attackers can modify, read, and partially disrupt Oracle Quality data through the Quality Workbench HTML interface.

Affected Products

Oracle E-Business Suite — Oracle Quality 12.2.3
Oracle E-Business Suite — Oracle Quality versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-62525

Vulnerability Analysis

The vulnerability resides in the Quality Workbench HTML system, a web-facing component of the Oracle Quality module in Oracle E-Business Suite. Oracle Quality manages product quality data, collection plans, specifications, and results across manufacturing workflows. The Quality Workbench HTML interface exposes these functions over HTTP to authenticated EBS users.

An attacker holding a low-privilege EBS session can reach the affected component through standard HTTP requests. Exploitation does not require user interaction. The impacts span confidentiality, integrity, and availability, though each is limited in scope: read and write access are constrained to a subset of Oracle Quality data, and the denial of service is partial rather than complete. The classification under [CWE-200] indicates unintended exposure of information to actors not explicitly authorized to receive it.

Root Cause

Oracle has not published detailed root cause information. Consistent with the [CWE-200] mapping and the mixed confidentiality-integrity-availability impact profile, the flaw involves improper access control or insufficient authorization checks within Quality Workbench HTML request handlers, allowing an authenticated low-privileged user to reach data operations beyond their intended role.

Attack Vector

Exploitation proceeds over the network using HTTP against the Oracle E-Business Suite front end. The attacker authenticates as any low-privileged EBS user, then issues requests to Quality Workbench HTML endpoints. Because attack complexity is low and no user interaction is required, exploitation is straightforward once credentials are obtained. Compromised or over-provisioned service accounts, contractor logins, and phished user credentials are the most likely paths to the required privilege level.

No public proof-of-concept, exploit code, or in-the-wild exploitation has been reported. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. See the Oracle Security Alert July 2026 for vendor-supplied technical details.

Detection Methods for CVE-2026-62525

Indicators of Compromise

Unexpected HTTP requests from low-privileged EBS user sessions to Quality Workbench HTML URLs under /OA_HTML/ associated with Oracle Quality functions.
Unauthorized INSERT, UPDATE, or DELETE operations against Oracle Quality tables (for example, tables in the QA schema) performed by non-Quality users.
HTTP 500 errors or partial service degradation on Quality Workbench pages coinciding with anomalous request volume.

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking to log user access to Quality Workbench HTML pages, then alert on access by roles that lack Quality responsibilities.
Correlate database audit logs for the Oracle Quality QA schema against the authenticated EBS user's assigned responsibilities to identify privilege boundary violations.
Deploy web application firewall rules or reverse-proxy logging in front of the EBS application tier to record and baseline traffic to /OA_HTML/ Quality endpoints.

Monitoring Recommendations

Baseline normal request rates and users for Quality Workbench HTML and alert on deviations sustained over short intervals.
Monitor for authentication anomalies on low-privileged EBS accounts, including impossible-travel logins and password sprays that could precede exploitation.
Track application-tier availability metrics for the Quality module to detect partial denial-of-service conditions early.

How to Mitigate CVE-2026-62525

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update patches for Oracle E-Business Suite 12.2.3 through 12.2.15 as documented in the Oracle Security Alert July 2026.
Inventory all EBS accounts with access to Oracle Quality responsibilities and revoke any that are unnecessary.
Restrict network exposure of the EBS application tier so Quality Workbench HTML endpoints are not reachable from untrusted networks.

Patch Information

Oracle addressed CVE-2026-62525 in the July 2026 Critical Patch Update. Administrators must download and apply the appropriate EBS 12.2 patch set through My Oracle Support and validate the fix against Oracle Quality functionality in a test environment before production rollout. See the Oracle Security Alert July 2026 for exact patch identifiers.

Workarounds

If patching must be deferred, disable or restrict user access to the Quality Workbench HTML responsibilities until the fix is applied.
Enforce multi-factor authentication for all EBS logins to raise the cost of obtaining the low-privileged credentials required for exploitation.
Place the EBS application tier behind a web application firewall and block or rate-limit anonymous and low-reputation sources targeting /OA_HTML/ paths.

bash

# Configuration example: restrict access to Quality Workbench HTML at the reverse proxy
# (Apache httpd fronting Oracle E-Business Suite)
<LocationMatch "^/OA_HTML/.*(QA|Quality).*">
    Require ip 10.0.0.0/8
    Require valid-user
</LocationMatch>
