CVE-2026-62503
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Time and Labor 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 high privileged attacker with network access via HTTP to compromise Oracle Time and Labor. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Time and Labor accessible data as well as unauthorized access to critical data or complete access to all Oracle Time and Labor accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Time and Labor. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L).

This vulnerability resides within Oracle Time and Labor component of the Oracle E-Business Suite, specifically within the Internal Operations module. The affected versions span from 12.2.3 through 12.2.15, indicating a significant attack surface across multiple release cycles. The vulnerability represents a critical security flaw that enables high privileged attackers to exploit network-based HTTP access points to compromise the entire Time and Labor system. This classification as easily exploitable suggests that the attack vector requires minimal technical expertise or resources to execute successfully.
The technical nature of this vulnerability stems from insufficient access controls and authentication mechanisms within the Internal Operations component. Attackers with high privileges and network connectivity can leverage this weakness to perform unauthorized operations including data creation, deletion, and modification across all accessible Oracle Time and Labor data. The vulnerability impacts three core security principles simultaneously: confidentiality through unauthorized data access, integrity via unauthorized modifications, and availability through potential partial denial of service conditions. The CVSS 3.1 score of 6.7 reflects the severity of these combined impacts, with high confidentiality and integrity risks balanced against moderate availability concerns.
The operational impact of this vulnerability extends beyond simple data compromise to include complete system subversion capabilities. Successful exploitation allows attackers to gain unauthorized access to critical business data including time tracking records, labor cost information, and related workforce management data that organizations rely upon for financial reporting and compliance purposes. The partial denial of service component creates additional operational disruption by potentially limiting access to essential time and labor processing functions. Organizations utilizing these specific Oracle E-Business Suite versions face significant risk of data integrity compromise and potential business continuity issues.
Mitigation strategies should prioritize immediate patch application from Oracle's security advisories for the affected versions. Network segmentation and access controls should be implemented to limit exposure of the Time and Labor component to unauthorized users. Regular monitoring of system logs for suspicious activities related to Internal Operations module access should be established. The vulnerability aligns with CWE-284 (Improper Access Control) and may map to ATT&CK techniques involving privilege escalation and data manipulation. Organizations should also consider implementing additional security controls such as web application firewalls and enhanced authentication mechanisms to reduce the attack surface and protect against potential exploitation attempts.
