CVE-2025-24485 is a server-side request forgery (SSRF) vulnerability classified under CWE-918, affecting MedDream PACS Premium version 7.3.5.860, specifically within the cecho.php component. SSRF vulnerabilities occur when an attacker can manipulate a server to make HTTP requests to arbitrary domains or internal network resources, potentially bypassing firewall restrictions and accessing sensitive internal systems. In this case, the vulnerability allows an unauthenticated attacker to craft HTTP requests that the vulnerable endpoint processes, causing the server to initiate requests on behalf of the attacker. The vulnerability requires user interaction but no prior authentication, increasing the attack surface. The CVSS 3.1 base score is 5.8, reflecting a medium severity due to the network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), and required user interaction (UI:R). The impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L), and the scope is changed (S:C), indicating that the vulnerability affects components beyond the vulnerable component itself. While no known exploits are currently reported in the wild and no patches have been released, the vulnerability poses a risk of internal network reconnaissance, potential access to sensitive medical data, or disruption of PACS services. MedDream PACS Premium is a medical imaging system widely used in healthcare environments to store and manage medical images, making this vulnerability particularly sensitive due to the critical nature of healthcare data and systems.

For European organizations, particularly healthcare providers using MedDream PACS Premium, this SSRF vulnerability could allow attackers to bypass perimeter defenses and access internal network resources that are not otherwise exposed. This could lead to unauthorized access to sensitive patient data, disruption of medical imaging services, or further lateral movement within the network. The confidentiality of protected health information (PHI) could be compromised, violating GDPR and other data protection regulations, potentially resulting in legal and financial penalties. The integrity and availability of PACS services could be affected, impacting clinical workflows and patient care. Given the critical role of PACS in diagnostics and treatment, any disruption could have serious operational consequences. The medium severity indicates a moderate risk, but the healthcare sector's sensitivity elevates the importance of timely mitigation. The lack of authentication requirement increases the risk of exploitation from external attackers, including those launching phishing campaigns to induce user interaction.

1. Network Segmentation: Isolate the PACS system within a secured network segment with strict firewall rules limiting outbound HTTP requests only to trusted destinations. 2. Input Validation and Filtering: Implement web application firewalls (WAFs) to detect and block suspicious SSRF payloads targeting cecho.php or related endpoints. 3. Monitoring and Logging: Enable detailed logging of HTTP requests to the PACS system and monitor for unusual or unexpected outbound requests that could indicate SSRF attempts. 4. User Awareness: Educate users about the risks of interacting with unsolicited or suspicious links that could trigger SSRF exploitation. 5. Vendor Coordination: Engage with MedDream to obtain patches or updates addressing this vulnerability and apply them promptly once available. 6. Access Controls: Restrict access to the PACS web interface to authorized personnel and trusted IP ranges to reduce exposure. 7. Incident Response Preparation: Develop and test incident response plans specific to SSRF exploitation scenarios within healthcare environments. 8. Regular Security Assessments: Conduct penetration testing and vulnerability scanning focused on SSRF and related web application vulnerabilities in PACS deployments.
