CVE-2026-70764 in General Ledger
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle General Ledger product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle General Ledger. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle General Ledger accessible data as well as unauthorized update, insert or delete access to some of Oracle General Ledger accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle General Ledger. CVSS 3.1 Base Score 7.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L).

The identified vulnerability resides within the Internal Operations component of Oracle General Ledger, a critical module in the Oracle E-Business Suite ecosystem used for managing financial data and accounting operations. This security flaw affects supported versions ranging from 12.2.3 through 12.2.15. The nature of this weakness allows an attacker with low privileges to exploit the system over HTTP network access, leading to a significant compromise of the application's integrity and confidentiality. Such vulnerabilities are particularly dangerous in enterprise environments because they can be leveraged by insiders or external actors who have gained initial foothold through lower-level credentials to escalate their impact on core financial systems.
From a technical perspective, this vulnerability enables unauthorized access to critical data within the General Ledger module. The exploitation vector is straightforward due to its network accessibility via HTTP and low authentication requirements, which aligns with common patterns seen in insecure direct object references or improper authorization checks. Once exploited, an attacker can read sensitive financial records that should be restricted based on role-based access controls. Furthermore, the flaw permits unauthorized modifications including updates, inserts, and deletes against accessible data. This capability directly undermines the integrity of financial reporting and transactional accuracy, which are paramount in any accounting system. The ability to alter or remove data without proper audit trails or permissions represents a severe breach of internal control mechanisms designed to prevent fraud and errors.
The operational impact extends beyond mere data exposure or modification. The vulnerability also allows for partial denial of service conditions against Oracle General Ledger services. This means that an attacker can disrupt the availability of critical financial processing functions, potentially halting business operations during peak periods such as month-end closing or fiscal year reporting. A CVSS 3.1 base score of 7.6 reflects this high severity, driven by high confidentiality impact alongside moderate integrity and availability impacts. The specific vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L) indicates that while the attack requires low privileges, it does not require user interaction and has a significant effect on data secrecy. This combination of factors makes it a priority for remediation to prevent both financial fraud and operational disruption.
In terms of industry standards classification, this vulnerability maps closely to CWE-862 Missing Authorization or CWE-915 Improperly Controlled Modification of Dynamically-Determined Object Attributes depending on the specific implementation details within the Internal Operations component. It also aligns with MITRE ATT&CK techniques related to Credential Access and Data Exfiltration if used for theft, as well as Impact tactics involving data manipulation and service disruption. Security teams should treat this not just as a patching issue but as a potential entry point for deeper lateral movement within the ERP environment if left unaddressed.
Mitigation strategies must prioritize immediate application of Oracle-provided security patches to bring affected systems up to date with current release levels where these flaws have been resolved. In addition to patching, organizations should enforce strict network segmentation to limit HTTP access to General Ledger components only from trusted internal subnets or through secure web gateways that inspect traffic for anomalous patterns. Implementing robust input validation and ensuring that all API endpoints within the Internal Operations component adhere to least-privilege principles will help mitigate exploitation risks. Regular audits of user permissions are essential to ensure that low-privileged accounts do not possess excessive rights over financial data modules, thereby reducing the attack surface available to potential adversaries seeking to compromise critical business functions.
