CVE-2026-70783 in Service Contracts
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Service Contracts 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 Service Contracts. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Service Contracts accessible data as well as unauthorized access to critical data or complete access to all Oracle Service Contracts accessible data. CVSS 3.1 Base Score 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle Service Contracts, a critical module within the Oracle E-Business Suite ecosystem. This flaw affects supported software versions ranging from 12.2.3 through 12.2.15, indicating that a significant portion of deployed enterprise environments remain susceptible to exploitation. The nature of this vulnerability is characterized by its difficulty to exploit, which suggests that while it does not allow for trivial automated attacks, it requires specific conditions or precise input manipulation to trigger successfully. Despite the high complexity required for execution, the potential impact on system integrity and confidentiality is severe, classifying it as a critical risk factor for organizations relying on this suite for their service management operations.
From a technical perspective, the vulnerability permits an unauthenticated attacker who has network access via HTTP to compromise the Oracle Service Contracts application. The absence of required authentication highlights a fundamental flaw in the access control mechanisms or input validation processes within the affected component. An adversary can leverage this weakness to perform unauthorized creation, deletion, or modification of critical data stored within the system. This capability extends beyond simple data viewing; it allows for active manipulation of business-critical records that govern service contracts, potentially leading to operational disruption, financial loss, or regulatory non-compliance depending on the nature of the modified data.
The operational impact of this vulnerability is substantial, primarily affecting the confidentiality and integrity aspects of the security triad as reflected in its CVSS 3.1 base score of 7.4. The vector string (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) indicates that while availability is not directly impacted, both confidentiality and integrity are severely compromised. Successful exploitation grants the attacker complete access to all Oracle Service Contracts accessible data or at least critical subsets thereof. This level of access enables an adversary to exfiltrate sensitive customer information, alter contractual terms, delete essential records, or inject malicious configurations that could undermine future business processes. The high impact on confidentiality and integrity underscores the necessity for immediate remediation efforts to prevent unauthorized data manipulation and exposure.
In alignment with industry standards, this vulnerability maps closely to CWE-269 Improper Privilege Management and CWE-862 Missing Authorization, as it allows unauthenticated users to perform actions that should be restricted. Furthermore, from a tactical standpoint consistent with the MITRE ATT&CK framework, this flaw facilitates techniques associated with Data Manipulation (T1074) and potentially Account Manipulation if new accounts are created for persistence. The network-based nature of the attack vector places it within the context of remote exploitation scenarios where attackers seek to establish a foothold or escalate privileges without prior credentials.
Mitigation strategies must prioritize immediate patching by applying the latest security updates provided by Oracle for versions 12.2.3 through 12.2.15. Organizations should verify their current version and apply the relevant patches as soon as they are available in the Oracle Critical Patch Update stream. In addition to software remediation, network-level controls such as Web Application Firewalls can be configured to detect and block anomalous HTTP requests that exhibit patterns consistent with exploitation attempts for this specific vulnerability. Implementing strict input validation on any exposed endpoints related to Internal Operations is also advisable if patching cannot occur immediately. Regular security assessments and penetration testing should include checks for similar authorization flaws in other modules of the E-Business Suite to ensure comprehensive protection against unauthenticated access vectors.
