The vulnerability EUVD-2025-34888 pertains to a server-side request forgery (SSRF) issue in Illia Cloud's illia-Builder software before version 4.8.5. The CVSS (Common Vulnerability Scoring System) base score of 9.6 indicates a critical severity level. The scoring vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal complexity to execute.
• Privileges Required (PR): Low (L) - The attacker needs low-level privileges to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required for the attack to succeed.
• Scope (S): Changed (C) - The vulnerability affects a different security scope.
• Confidentiality (C): High (H) - There is a high impact on confidentiality.
• Integrity (I): High (H) - There is a high impact on integrity.
• Availability (A): None (N) - There is no impact on availability.

This high severity score underscores the critical nature of the vulnerability, necessitating immediate attention and remediation.

2. Potential Attack Vectors and Exploitation Methods

An attacker with authenticated access can exploit this SSRF vulnerability by sending crafted requests through the API. Potential attack vectors include:

• Port Scanning: Enumerating open ports on internal services by analyzing response discrepancies.
• Internal Service Interaction: Sending requests to internal services that are not intended to be accessible from the external network.
• Data Exfiltration: Accessing sensitive data from internal services that are not properly secured.
• Service Disruption: Potentially disrupting internal services by sending malicious requests.

Exploitation methods may involve:

• Crafting Malicious Requests: Using tools like Burp Suite or custom scripts to craft and send requests.
• Automated Scanning: Utilizing automated tools to scan for open ports and services.
• Exploiting Trust Relationships: Leveraging the trust relationships between internal services to gain unauthorized access.

3. Affected Systems and Software Versions

The vulnerability affects Illia Cloud's illia-Builder software versions before 4.8.5. Organizations using these versions are at risk and should prioritize updating to the latest version to mitigate the threat.

4. Recommended Mitigation Strategies

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

• Update Software: Immediately update to Illia Cloud illia-Builder version 4.8.5 or later.
• Network Segmentation: Implement strict network segmentation to limit the exposure of internal services.
• Access Controls: Enforce strict access controls and authentication mechanisms to limit who can send requests through the API.
• Monitoring and Logging: Implement robust monitoring and logging to detect and respond to suspicious activities.
• Input Validation: Enhance input validation and sanitization for API requests to prevent malicious inputs.
• Firewall Rules: Configure firewall rules to restrict access to internal services from unauthorized sources.
