CVE-2026-61015: Oracle Time and Labor Information Disclosure

CVE-2026-61015 Overview

CVE-2026-61015 is an information disclosure vulnerability in the Oracle Time and Labor product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. An unauthenticated attacker with network access via HTTP can exploit the weakness to obtain unauthorized read access to a subset of Oracle Time and Labor data. Oracle rates exploitation as difficult, and the impact is limited to confidentiality of a subset of data. The vulnerability was published in the Oracle Security Alert July 2026.

Critical Impact
Unauthenticated remote attackers can read a subset of Oracle Time and Labor data over HTTP without user interaction.

Technical Details for CVE-2026-61015

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Time and Labor, a module of Oracle E-Business Suite used to capture and manage employee time and attendance data. An attacker reaches the vulnerable code path over HTTP without authentication or user interaction. Successful exploitation results in read-only exposure of a subset of application data. Integrity and availability of the application are not affected. Oracle characterizes the attack complexity as high, meaning the attacker must satisfy conditions outside their direct control, such as specific configuration or timing states. The current EPSS probability is 0.258% with a percentile of 17.376, indicating low observed exploitation likelihood at this time.

Root Cause

Oracle has not disclosed the underlying defect. The Critical Patch Update advisory attributes the issue to the Internal Operations component of Oracle Time and Labor and classifies the impact as a confidentiality issue. Based on the vector, the root cause is an information exposure flaw reachable through an HTTP-facing interface that returns application data without adequate authorization checks under specific conditions. Refer to the Oracle Security Alert July 2026 for vendor detail.

Attack Vector

The attacker sends crafted HTTP requests to a network-accessible Oracle E-Business Suite instance hosting Oracle Time and Labor. No credentials, tokens, or user interaction are required. Because attack complexity is high, exploitation depends on state or configuration outside the attacker's direct control. When conditions align, the response leaks a subset of data managed by the Time and Labor module.

No verified proof-of-concept code is publicly available. See the Oracle

Detection Methods for CVE-2026-61015

Indicators of Compromise

Unauthenticated HTTP requests to Oracle E-Business Suite Time and Labor endpoints originating from unexpected external sources.
Anomalous HTTP 200 responses of atypical size returned from Time and Labor URLs to unauthenticated sessions.
Access log entries showing repeated probing of /OA_HTML/ paths associated with the Internal Operations component.

Detection Strategies

Correlate web server access logs on Oracle HTTP Server with application logs to identify unauthenticated access to Time and Labor URLs.
Baseline expected client IP ranges for Oracle E-Business Suite and alert on requests from outside those ranges.
Monitor for scanning patterns targeting Oracle E-Business Suite fingerprints, such as /OA_HTML/AppsLocalLogin.jsp reconnaissance followed by module-specific requests.

Monitoring Recommendations

Forward Oracle HTTP Server and application tier logs to a central SIEM for continuous review.
Enable auditing on the Oracle Time and Labor schema to record data access patterns and flag deviations.
Track outbound response sizes from Time and Labor URLs to detect bulk data returns to unauthenticated clients.

How to Mitigate CVE-2026-61015

Immediate Actions Required

Apply the fixes from the Oracle Critical Patch Update - July 2026 to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
Restrict network access to Oracle E-Business Suite so only trusted networks and VPN users can reach the Time and Labor endpoints.
Inventory internet-exposed Oracle E-Business Suite instances and prioritize them for patching first.

Patch Information

Oracle addressed CVE-2026-61015 in the July 2026 Critical Patch Update. Administrators should download the applicable patch for Oracle E-Business Suite 12.2.x from My Oracle Support and apply it following Oracle's documented adop procedure. Full details are in the Oracle Security Alert July 2026.

Workarounds

Place Oracle E-Business Suite behind a reverse proxy or web application firewall that enforces authentication before requests reach the Time and Labor module.
Disable or block external HTTP access to Time and Labor URLs if the module is not required for external users.
Enforce IP allowlisting at the network edge for management and self-service interfaces of Oracle E-Business Suite.

bash

# Example: restrict access to Oracle E-Business Suite Time and Labor URLs
# in Oracle HTTP Server configuration (httpd.conf / mod_authz_host)
<Location /OA_HTML/>
    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
</Location>
