CVE-2026-62486 in Contracts Integration
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Contracts Integration product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Contracts Integration. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Contracts Integration accessible data as well as unauthorized read access to a subset of Oracle Contracts Integration accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Contracts Integration. CVSS 3.1 Base Score 5.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L).

Analysis

This vulnerability exists within Oracle Contracts Integration, a component of the Oracle E-Business Suite ecosystem that handles contract management and integration processes. The affected versions span from 12.2.3 through 12.2.15, representing a significant release range that suggests this flaw has persisted across multiple maintenance cycles. The vulnerability is classified as difficult to exploit, indicating that while it requires some level of sophistication, it remains a genuine threat to organizations running these legacy systems. The attack vector operates through HTTP network access, meaning that an unauthenticated attacker could potentially leverage this weakness without requiring valid credentials.
The technical nature of this vulnerability stems from insufficient validation mechanisms within the Internal Operations component of Oracle Contracts Integration. This flaw allows for unauthorized modifications to data through update, insert, or delete operations against specific subsets of accessible data. Additionally, attackers can gain unauthorized read access to portions of the system's data repository, potentially exposing sensitive contractual information. The partial denial of service aspect indicates that while complete system collapse may not occur, certain functionalities could be degraded or rendered unavailable to legitimate users. This vulnerability aligns with CWE-284 (Improper Access Control) and represents a classic case of insufficient privilege checking within business application logic.
The operational impact of this vulnerability extends beyond simple data compromise, as it affects the fundamental integrity and availability of contract management processes. Organizations relying on Oracle Contracts Integration for critical business operations face potential financial exposure through unauthorized contract modifications or data theft. The requirement for human interaction suggests that social engineering or targeted phishing attacks may be necessary to initiate exploitation, though this does not eliminate the automated nature of the underlying vulnerability. Attackers could potentially manipulate contract terms, alter payment arrangements, or access confidential business information, leading to both direct financial losses and reputational damage.
Mitigation strategies should prioritize immediate patching of affected Oracle E-Business Suite versions to the latest available releases that address this specific vulnerability. Organizations should implement network segmentation to limit unnecessary HTTP access to the Oracle Contracts Integration components and establish robust monitoring for unusual access patterns or data modifications. Security teams must conduct comprehensive vulnerability assessments to identify all instances of affected software within their environment, as the vulnerability affects multiple versions across the 12.2.x release series. The CVSS 3.1 score of 5.0 indicates a medium severity threat that requires prompt attention, particularly given the potential for data integrity compromise and partial service disruption. Organizations should also consider implementing additional access controls and authentication mechanisms to reduce the attack surface, as the vulnerability's classification under ATT&CK technique T1212 (Exploitation for Credential Access) suggests it could be leveraged for broader system compromise attempts.
