CVE-2025-50107 is a vulnerability identified in the Oracle Universal Work Queue component of the Oracle E-Business Suite, specifically affecting versions 12.2.5 through 12.2.14. This vulnerability allows an unauthenticated attacker with network access via HTTP to exploit the system. The attack requires human interaction from a person other than the attacker, indicating a social engineering element or tricking a legitimate user to perform some action. The vulnerability impacts the request handling functionality within the Oracle Universal Work Queue, which is a critical component used for managing and processing work requests in Oracle's enterprise applications. Successful exploitation can lead to unauthorized update, insert, or delete operations on some data accessible through the Universal Work Queue, as well as unauthorized read access to a subset of that data. The vulnerability has a CVSS 3.1 base score of 6.1, categorized as medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), required user interaction (UI:R), scope change (S:C), and impacts on confidentiality and integrity but no impact on availability (C:L/I:L/A:N). The scope change means that while the vulnerability is in the Universal Work Queue, it may affect additional Oracle products that rely on or integrate with this component. The CWE associated is CWE-284, which relates to improper access control. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that organizations should prioritize monitoring and prepare for patching once available. The requirement for user interaction suggests phishing or social engineering could be part of the attack chain, increasing the risk of exploitation in environments where users may be tricked into performing actions that facilitate the attack.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Oracle E-Business Suite for critical business processes. Unauthorized modification (update, insert, delete) and unauthorized read access to data can lead to data integrity issues, leakage of sensitive business information, and potential disruption of workflows. The scope change implies that other integrated Oracle products could be indirectly affected, potentially amplifying the impact across multiple systems. Confidentiality and integrity impacts could result in regulatory compliance issues under GDPR if personal or sensitive data is exposed or altered without authorization. The requirement for user interaction means that internal users could be targeted via phishing campaigns, increasing the risk of successful exploitation in organizations with less mature security awareness programs. The medium severity score suggests a moderate risk but combined with the widespread use of Oracle E-Business Suite in Europe, the potential for business disruption and data compromise is non-trivial. Organizations in sectors such as finance, manufacturing, and public administration, which heavily use Oracle applications, may face operational and reputational damage if exploited.

1. Implement strict network segmentation and firewall rules to limit HTTP access to Oracle Universal Work Queue components only to trusted internal networks and users. 2. Enhance user awareness training focusing on phishing and social engineering tactics to reduce the likelihood of successful user interaction exploitation. 3. Monitor network traffic and application logs for unusual activities related to Oracle Universal Work Queue, such as unexpected data modification or access patterns. 4. Apply principle of least privilege to Oracle E-Business Suite users, ensuring that only necessary permissions are granted to minimize the impact of unauthorized actions. 5. Deploy web application firewalls (WAF) with custom rules to detect and block suspicious HTTP requests targeting the Universal Work Queue endpoints. 6. Prepare for rapid patch deployment by establishing a vulnerability management process that includes testing and applying Oracle patches as soon as they become available. 7. Conduct regular security assessments and penetration testing focused on Oracle E-Business Suite components to identify and remediate potential attack vectors. 8. Consider implementing multi-factor authentication (MFA) for access to Oracle applications to add an additional layer of defense against unauthorized access.
