CVE-2025-50067 is a critical vulnerability affecting Oracle Application Express (APEX), specifically versions 24.2.4 and 24.2.5, within the Strategic Planner Starter App component. This vulnerability is classified under CWE-601, which relates to URL redirection or forwarding issues that can be exploited to redirect users to malicious sites. The vulnerability allows a low-privileged attacker with network access via HTTP to compromise Oracle APEX. Exploitation requires user interaction from a person other than the attacker, indicating a social engineering element such as phishing or tricking a user into clicking a malicious link. Successful exploitation can lead to a complete takeover of Oracle APEX, impacting confidentiality, integrity, and availability of the system. The CVSS 3.1 base score is 9.0, reflecting critical severity with network attack vector, low attack complexity, low privileges required, and user interaction needed. The scope is changed, meaning the vulnerability in Oracle APEX can affect additional products integrated or dependent on it. Although no known exploits are currently in the wild, the ease of exploitation and the critical impact make this a significant threat. Oracle APEX is widely used for developing web applications on Oracle databases, often in enterprise environments, making this vulnerability a high-risk issue for organizations relying on this platform for business-critical applications.

For European organizations, the impact of CVE-2025-50067 can be substantial. Oracle APEX is commonly used in government, finance, healthcare, and large enterprises across Europe for rapid application development and deployment. A successful attack could lead to unauthorized access to sensitive data, manipulation or destruction of business-critical applications, and potential lateral movement to other integrated Oracle products or systems. The requirement for user interaction means phishing or social engineering campaigns could be leveraged to exploit this vulnerability, increasing the risk to organizations with large user bases. The scope change indicates that beyond Oracle APEX, other Oracle products or connected systems could be compromised, amplifying the potential damage. This could result in data breaches, operational disruptions, regulatory non-compliance (e.g., GDPR violations), and reputational damage. Given the criticality and network accessibility, attackers could target European organizations remotely, making it a pressing concern for cybersecurity teams.

To mitigate CVE-2025-50067, European organizations should: 1) Immediately identify and inventory all Oracle APEX instances, specifically versions 24.2.4 and 24.2.5, to assess exposure. 2) Apply any available patches or updates from Oracle as soon as they are released; if patches are not yet available, consider temporary mitigations such as disabling the Strategic Planner Starter App component or restricting HTTP access to Oracle APEX interfaces via network segmentation and firewall rules. 3) Implement strict access controls and multi-factor authentication (MFA) for Oracle APEX users to reduce the risk of credential misuse. 4) Conduct targeted user awareness training focused on phishing and social engineering risks, emphasizing the need to avoid interacting with suspicious links or requests. 5) Monitor network traffic and application logs for unusual activities, especially HTTP requests that could indicate exploitation attempts or redirection abuse. 6) Employ web application firewalls (WAFs) with rules tuned to detect and block suspicious URL redirection or manipulation patterns. 7) Review and harden integration points between Oracle APEX and other Oracle or third-party products to limit scope expansion in case of compromise. 8) Prepare incident response plans specific to Oracle APEX compromise scenarios to enable rapid containment and recovery.
