The vulnerability in question, identified as EUVD-2025-35253 (CVE-2025-61757), affects Oracle Fusion Middleware's Identity Manager product, specifically within the REST WebServices component. The CVSS 3.1 Base Score of 9.8 indicates a critical severity level. This score is derived from the following CVSS vector:

• Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources to exploit.
• Privileges Required (PR): None (N) - No authentication is required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required for the attack to succeed.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - The vulnerability allows for unauthorized access to sensitive information.
• Integrity (I): High (H) - The vulnerability allows for unauthorized modification of data.
• Availability (A): High (H) - The vulnerability allows for disruption of service.

Given these factors, the vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected systems.

2. Potential Attack Vectors and Exploitation Methods

The vulnerability allows an unauthenticated attacker with network access via HTTP to compromise the Identity Manager. Potential attack vectors include:

• Network Scanning: Attackers can scan for vulnerable instances of Oracle Identity Manager exposed to the internet.
• Exploit Kits: Automated tools or scripts can be developed to exploit this vulnerability, making it easier for attackers to target multiple systems.
• Man-in-the-Middle (MitM) Attacks: Intercepting HTTP traffic to inject malicious payloads.
• Phishing: Tricking users into visiting malicious sites that exploit the vulnerability.

Exploitation methods may involve sending specially crafted HTTP requests to the REST WebServices component, leading to unauthorized access and potential takeover of the Identity Manager.

3. Affected Systems and Software Versions

The affected versions of Oracle Identity Manager are:

• 12.2.1.4.0
• 14.1.2.1.0

Organizations using these versions are at risk and should prioritize mitigation efforts.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Patch Management: Apply the latest security patches provided by Oracle. Refer to the Oracle security alert for specific patch information.
• Network Segmentation: Isolate the Identity Manager from public networks to limit exposure.
• Access Controls: Implement strict access controls and authentication mechanisms to restrict unauthorized access.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities.
• Firewall Rules: Configure firewalls to block unauthorized access to the REST WebServices component.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address potential weaknesses.
