CVE-2026-70941 in Payroll
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Payroll 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 logon to the infrastructure where Oracle Payroll executes to compromise Oracle Payroll. While the vulnerability is in Oracle Payroll, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Payroll. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

The identified vulnerability resides within the Internal Operations component of Oracle Payroll, a critical module within the broader Oracle E-Business Suite ecosystem. This security flaw affects supported software versions ranging from 12.2.3 through 12.2.15. The nature of this defect allows for exploitation by an attacker who possesses low-level privileges and has established logon access to the infrastructure hosting the Oracle Payroll application. Unlike vulnerabilities that require high-privileged accounts or complex social engineering, this flaw can be leveraged by users with minimal initial access rights, significantly lowering the barrier to entry for malicious actors targeting enterprise payroll systems.
From a technical perspective, the vulnerability enables an unauthorized actor to compromise the integrity and availability of the Oracle Payroll environment. The core issue lies in insufficient validation or access control mechanisms within the internal operations logic, which permits privilege escalation or arbitrary code execution when triggered by authenticated but low-privileged users. This architectural weakness means that once an attacker gains a foothold on the infrastructure through legitimate credentials obtained via phishing, credential stuffing, or insider threats, they can exploit this specific flaw to escalate their privileges and take full control of the application layer. The impact is not confined solely to the payroll module; due to the interconnected nature of enterprise resource planning systems, successful exploitation leads to a scope change where additional products within the E-Business Suite may be compromised, potentially exposing sensitive financial data or disrupting broader business operations.
The operational impact of this vulnerability is severe, as reflected by its CVSS 3.1 Base Score of 8.8, classified as High severity. The vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) indicates that the attack requires local network access but has low complexity and no user interaction requirements beyond initial authentication. Most critically, the scope change from C to S signifies that the vulnerability affects resources outside the vulnerable component's security authority. The high impacts on Confidentiality, Integrity, and Availability mean that attackers can exfiltrate sensitive employee financial data, alter payroll records for fraudulent purposes, or disrupt critical business processes by rendering the system unavailable. This triad of impacts poses a significant risk to organizational reputation, regulatory compliance, and financial stability.
In terms of industry standard classifications, this vulnerability aligns with CWE-269 Improper Privilege Management, as it allows an actor to escalate privileges beyond their intended level. It also maps to MITRE ATT&CK techniques such as T1078 Valid Accounts, where attackers use legitimate credentials to gain access, and potentially T1053 Scheduled Task/Job or other execution methods depending on the specific exploitation vector within the internal operations module. The lack of user interaction requirement (UI:N) further emphasizes the stealthy nature of the attack, allowing for automated exploitation scripts that can rapidly compromise systems once initial access is established.
To mitigate this risk, organizations must prioritize immediate patching to apply the latest security updates provided by Oracle for versions 12.2.3 through 12.2.15. It is essential to verify that all instances of Oracle Payroll within the E-Business Suite environment are updated consistently to prevent partial exposure. In addition to patching, implementing strict network segmentation can limit lateral movement if an attacker gains initial access. Enforcing multi-factor authentication for all user accounts reduces the likelihood of credential compromise, while rigorous monitoring and logging should be deployed to detect anomalous activities indicative of privilege escalation attempts. Regular audits of user permissions ensure that low-privileged users do not possess unnecessary access rights to sensitive infrastructure components, thereby reducing the attack surface available to potential adversaries.
