CVE-2025-50073 is a vulnerability in Oracle WebLogic Server, specifically within the Web Container component of Oracle Fusion Middleware. It affects versions 12.2.1.4.0, 14.1.1.0.0, and 14.1.2.0.0. The vulnerability allows an unauthenticated attacker with network access via HTTP to compromise the WebLogic Server. Exploitation requires user interaction from a person other than the attacker, indicating a social engineering element or tricking a legitimate user to perform an action. The vulnerability results in a scope change, meaning that although it resides in WebLogic Server, it can impact additional Oracle products that rely on or integrate with WebLogic. Successful exploitation can lead to unauthorized update, insert, or delete operations on some data accessible through WebLogic Server, as well as unauthorized read access to a subset of that data. The CVSS 3.1 base score is 6.1, reflecting medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and low confidentiality and integrity impacts (C:L/I:L), with no availability impact (A:N). The CWE associated is CWE-285, which relates to improper authorization. No known exploits are currently reported in the wild, and no patches are linked yet. This vulnerability poses a risk of data compromise and unauthorized data manipulation within affected WebLogic environments, potentially cascading to other integrated Oracle products due to the scope change.

For European organizations, the impact of CVE-2025-50073 can be significant, particularly for those relying on Oracle WebLogic Server for critical business applications, middleware services, or integrated enterprise systems. Unauthorized read access could lead to exposure of sensitive or confidential information, including personal data protected under GDPR, intellectual property, or business-critical data. Unauthorized update, insert, or delete operations could compromise data integrity, disrupt business processes, or corrupt application states, potentially causing operational downtime or erroneous business decisions. The requirement for user interaction suggests phishing or social engineering could be vectors, increasing risk in organizations with large user bases or less mature security awareness programs. The scope change implies that the vulnerability could affect not only WebLogic Server but also other Oracle products that depend on it, broadening the potential impact footprint. This could affect sectors such as finance, manufacturing, telecommunications, and government agencies across Europe that use Oracle middleware extensively. The medium severity score indicates a moderate but non-trivial risk, necessitating timely mitigation to avoid exploitation and data breaches.

European organizations should implement a multi-layered mitigation approach: 1) Monitor Oracle’s official channels closely for patches or security advisories related to CVE-2025-50073 and apply updates promptly once available. 2) Until patches are released, restrict network access to Oracle WebLogic Server instances to trusted internal networks or VPNs, minimizing exposure to unauthenticated external attackers. 3) Implement strict web application firewall (WAF) rules to detect and block suspicious HTTP requests targeting WebLogic Server endpoints. 4) Enhance user awareness training focused on recognizing and avoiding social engineering or phishing attempts, as exploitation requires user interaction. 5) Conduct regular audits and monitoring of WebLogic Server logs to detect unusual read or write operations that could indicate exploitation attempts. 6) Review and tighten access controls and authorization policies within WebLogic Server to limit data exposure and modification capabilities. 7) Segment Oracle middleware environments from other critical infrastructure to contain potential scope change impacts. 8) Employ intrusion detection/prevention systems (IDS/IPS) tuned for WebLogic-specific attack signatures. These specific steps go beyond generic advice by focusing on network segmentation, user training, and proactive monitoring tailored to the nature of this vulnerability.
