How CVE-2026-62474 Works
CVE-2026-62474 is an improper authorization vulnerability affecting the Oracle Lease and Finance Management product within the Oracle E-Business Suite. The flaw resides specifically in the Lease Authoring component, which governs the creation and management of lease contracts. The vulnerability affects Oracle Lease and Finance Management versions 12.2.3 through 12.2.15.
The root cause of this vulnerability is inadequate authorization controls within the Lease Authoring module. The software fails to properly enforce access restrictions when processing requests, allowing low-privileged users to bypass normal security checks. This flaw aligns with CWE-285 (Improper Authorization) and is also associated with CWE-269 (Improper Privilege Management) and CWE-306 (Missing Authentication for Critical Function).
The vulnerability is easily exploitable and requires low attacker privileges. An attacker with a valid low-privilege account can exploit this flaw remotely over HTTP network access. No user interaction is required, and the attack complexity is low, making it particularly dangerous.
Once exploited, the vulnerability grants the attacker three primary capabilities:
– Unauthorized read access to a subset of sensitive financial data managed by the application.
– Unauthorized update, insert, or delete access to some of the accessible data, enabling data manipulation.
– Partial denial of service (partial DOS) capability, which can disrupt lease management workflows and financial processing cycles.
From a cybersecurity framework perspective, this vulnerability maps to MITRE ATT&CK techniques T1078 (Valid Accounts) and T1499 (Endpoint Denial of Service). The combination of data manipulation with partial denial of service creates a multi-faceted threat that can compromise both operational integrity and financial reporting accuracy. The vulnerability’s CVSS 3.1 Base Score is 6.3 (MEDIUM), with the vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L.
Currently, no public exploit is available, and technical details remain undisclosed. However, the exploitability is considered easy, and the estimated exploit price ranges between $5,000 and $25,000.

What Undercode Say:
The following analytics and reconnaissance commands can be used to assess exposure and detect potential exploitation of CVE-2026-62474.
1. Check Oracle E-Business Suite Version
sqlplus apps/apps_password <<EOF SELECT RELEASE_NAME, VERSION FROM FND_PRODUCT_VERSIONS WHERE PATCH_LEVEL LIKE '12.2.%'; EOF
2. Identify Lease Authoring Module Endpoints
List all HTTP endpoints related to Lease Authoring grep -r "LeaseAuthoring" $ORACLE_HOME/forms/ grep -r "OZF" $ORACLE_HOME/forms/ OZF is the Lease Management module prefix
3. Audit User Privileges for Lease Authoring
SELECT USER_NAME, RESPONSIBILITY_NAME, SECURITY_GROUP_NAME FROM FND_USER_RESP_GROUPS WHERE RESPONSIBILITY_NAME LIKE '%Lease%';
4. Monitor for Anomalous HTTP Access Patterns
Monitor Apache/OHS access logs for suspicious Lease Authoring requests tail -f $ORACLE_INSTANCE/diagnostics/logs/OHS/ohs1/access_log | \ grep -E "(OZF|LeaseAuthoring|createLease|updateLease)"
5. Check for Partial DOS Indicators
Monitor database session count for unexpected spikes sqlplus apps/apps_password <<EOF SELECT COUNT() FROM V\$SESSION WHERE MODULE LIKE '%Lease%'; EOF
Exploit:
While no public exploit is available for CVE-2026-62474, the following conceptual attack flow outlines how an attacker would exploit this vulnerability:
1. Authentication: Attacker obtains valid low-privilege credentials for the Oracle E-Business Suite instance (e.g., via phishing, credential reuse, or social engineering).
2. HTTP Request Crafting: Attacker crafts a malicious HTTP request targeting the Lease Authoring component (endpoints such as /OZFLeaseAuthoring, /OZFLeaseCreation, or similar Oracle Forms/ADF-based URLs).
3. Authorization Bypass: The crafted request manipulates parameters or session tokens to bypass authorization checks, exploiting the improper access control logic in the Lease Authoring module.
4. Data Manipulation: The attacker sends UPDATE, INSERT, or DELETE operations to modify lease records, potentially altering financial data, revenue recognition, or compliance reports.
5. Data Exfiltration: The attacker issues SELECT queries to read sensitive financial data from the underlying database.
6. Partial DOS: The attacker floods the Lease Authoring service with malicious requests or triggers resource-intensive operations, causing partial denial of service.
Example Conceptual HTTP Request (for educational purposes only):
POST /OZFLeaseAuthoring/updateLease HTTP/1.1 Host: oracle-ebs.example.com Cookie: JSESSIONID=xyz123 Content-Type: application/x-www-form-urlencoded leaseId=12345&amount=999999&status=APPROVED&_PRIVILEGE_OVERRIDE=true
Protection:
- Apply Oracle Patches Immediately: Oracle has released a security patch for this vulnerability. Organizations should apply the Oracle Critical Patch Update (CPU) for July 2026 or the specific patch addressing CVE-2026-62474 to all affected instances (versions 12.2.3 through 12.2.15).
- Review and Harden User Permissions: Conduct a comprehensive access control review to identify and remediate unauthorized user permissions. Ensure that only authorized personnel have Lease Authoring privileges. Implement the principle of least privilege across all Oracle E-Business Suite modules.
- Implement Network Segmentation: Deploy network segmentation to restrict access to the Oracle E-Business Suite from untrusted networks. Limit HTTP access to the Lease Authoring component to trusted IP ranges and internal networks only.
- Deploy Web Application Firewall (WAF): Configure WAF rules to detect and block anomalous HTTP requests targeting Lease Authoring endpoints. Implement rate-limiting and request validation to mitigate potential DOS attempts.
- Enable Comprehensive Monitoring: Deploy monitoring systems to detect anomalous access patterns, including unusual database queries, unexpected session activities, and abnormal HTTP request volumes. Implement SIEM alerts for Lease Authoring module events.
- Strengthen Identity and Access Management (IAM): Implement robust IAM controls, including multi-factor authentication (MFA) for all Oracle E-Business Suite users. Regularly rotate credentials and enforce strong password policies.
- Conduct Regular Security Assessments: Perform regular vulnerability scanning and penetration testing specifically targeting Oracle E-Business Suite components. Include Lease Authoring module in all security assessments.
- Implement Audit Trails: Enhance audit logging and transaction logging to detect and investigate unauthorized activities. Retain logs for forensic analysis and compliance reporting.
Impact:
- Confidentiality Impact (LOW): Unauthorized read access to a subset of sensitive financial data, including lease contracts, payment schedules, revenue recognition data, and customer financial information. This could lead to data breaches and exposure of proprietary business information.
- Integrity Impact (LOW): Unauthorized update, insert, or delete operations against database records. Attackers can manipulate lease amounts, approval statuses, contract terms, and compliance data, potentially leading to fraudulent financial reporting, incorrect revenue recognition, and regulatory non-compliance.
- Availability Impact (LOW): Partial denial of service that disrupts lease management workflows and financial processing cycles. Organizations may experience operational delays, inability to process new leases, and interruptions to month-end closing processes.
- Financial and Operational Risk: The combination of data manipulation and partial DOS creates significant financial risk. Manipulated lease data can impact balance sheets, revenue forecasts, and audit trails. Operational disruptions can delay critical business processes and damage customer trust.
- Compliance Risk: Organizations subject to financial regulations (e.g., SOX, IFRS, GAAP) may face compliance violations if lease data integrity is compromised. This could result in regulatory fines, audit failures, and reputational damage.
- Attack Surface: With versions 12.2.3 through 12.2.15 affected, a significant number of Oracle E-Business Suite deployments are vulnerable. Organizations running these versions are at elevated risk until patches are applied.
- Exploit Market: The estimated exploit price of $5,000-$25,000 indicates active interest from threat actors. As no public exploit currently exists, organizations have a limited window to patch before weaponized exploits emerge.
