CVE-2025-53036 is a vulnerability in the Oracle Financial Services Analytical Applications Infrastructure platform component, affecting versions 8.0.7.9, 8.0.8.7, and 8.1.2.5. The flaw allows an unauthenticated attacker with network access via HTTP to exploit the system without any user interaction or privileges, leading to unauthorized access to critical data. The vulnerability is classified under CWE-200, indicating exposure of sensitive information to unauthorized actors. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N) highlights that the attack can be launched remotely over the network with low complexity, no privileges, and no user interaction, and it causes a high confidentiality impact with a scope change, meaning the attacker can access data beyond the initially vulnerable component. While the vulnerability is localized to the Oracle Financial Services Analytical Applications Infrastructure, exploitation could impact additional Oracle products due to shared components or integration, broadening the attack surface. The vulnerability was published on October 21, 2025, and no public exploits have been reported yet, but the ease of exploitation and the critical nature of the data involved make it a significant threat. The lack of available patches at the time of reporting increases the urgency for organizations to implement compensating controls.

For European organizations, particularly those in the financial sector using Oracle Financial Services Analytical Applications Infrastructure, this vulnerability poses a severe risk to confidentiality of sensitive financial data. Unauthorized access could lead to exposure of customer financial records, internal analytics, and strategic business information, potentially resulting in regulatory non-compliance, reputational damage, and financial losses. The scope change indicates that the impact could extend beyond the initially affected product to other integrated Oracle solutions, amplifying the risk. Given the criticality of financial data and stringent data protection regulations such as GDPR, a breach could trigger significant legal and financial consequences. Additionally, the vulnerability could be leveraged for espionage or fraud by threat actors targeting European financial institutions. The ease of exploitation without authentication or user interaction increases the likelihood of attacks, especially if network access controls are insufficient.

1. Immediately assess and inventory all Oracle Financial Services Analytical Applications Infrastructure instances to identify affected versions (8.0.7.9, 8.0.8.7, 8.1.2.5). 2. Apply vendor patches as soon as they become available; monitor Oracle security advisories closely. 3. Until patches are released, implement strict network segmentation and firewall rules to restrict HTTP access to the affected infrastructure only to trusted internal networks and management stations. 4. Deploy Web Application Firewalls (WAF) with custom rules to detect and block suspicious HTTP requests targeting known vulnerable endpoints. 5. Enable detailed logging and monitoring of HTTP traffic to and from the Oracle Financial Services Analytical Applications Infrastructure to detect anomalous access patterns. 6. Conduct regular vulnerability scans and penetration tests focusing on this vulnerability and related Oracle products to identify exposure. 7. Review and enforce least privilege access policies for all users and services interacting with the affected infrastructure. 8. Educate security teams about the vulnerability specifics to ensure rapid detection and response. 9. Prepare incident response plans tailored to potential data breaches involving this vulnerability. 10. Coordinate with Oracle support and security teams for timely updates and guidance.
