CVE-2025-24485 is a server-side request forgery (SSRF) vulnerability identified in the cecho.php functionality of MedDream PACS Premium version 7.3.5.860. MedDream PACS Premium is a medical imaging software used for storing, retrieving, and managing medical images (Picture Archiving and Communication System). The vulnerability allows an unauthenticated attacker to send a specially crafted HTTP request that triggers the server to make unintended HTTP requests to internal or external resources. SSRF vulnerabilities exploit the trust a server has in its own network or other systems it can access, potentially allowing attackers to access internal services, bypass firewalls, or exfiltrate sensitive information. In this case, the vulnerability does not require authentication but does require user interaction (UI:R), which might mean the attacker needs to trick a user into triggering the request. The CVSS 3.1 base score is 5.8 (medium severity), with vector AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:L, indicating network attack vector, high attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability's presence in a critical healthcare system raises concerns about potential misuse. The SSRF could be leveraged to access internal hospital networks, retrieve sensitive patient data, or pivot to other internal systems, potentially impacting confidentiality, integrity, and availability of medical data and services.

For European organizations, particularly healthcare providers using MedDream PACS Premium, this vulnerability poses a significant risk. PACS systems store sensitive patient imaging data protected under GDPR, and unauthorized access or data leakage could lead to severe privacy violations and regulatory penalties. SSRF exploitation could allow attackers to access internal hospital networks, potentially leading to lateral movement, data exfiltration, or disruption of medical services. Given the critical nature of healthcare infrastructure, any disruption or data breach could impact patient care and trust. Additionally, the vulnerability's unauthenticated nature increases the risk of exploitation from external attackers, including cybercriminals or state-sponsored actors targeting healthcare institutions. The medium severity rating suggests moderate impact, but the criticality of the affected system amplifies the potential consequences.

1. Immediate patching: Although no patch links are provided, organizations should monitor MedDream vendor advisories for patches or updates addressing CVE-2025-24485 and apply them promptly. 2. Network segmentation: Isolate PACS servers from general network traffic and restrict outbound HTTP requests from these servers to only trusted destinations, minimizing SSRF exploitation scope. 3. Web application firewall (WAF): Deploy and configure WAF rules to detect and block suspicious SSRF patterns targeting cecho.php or similar endpoints. 4. Input validation and filtering: Implement strict validation on any user-supplied input that influences server-side requests, ensuring only allowed URLs or IP addresses can be accessed. 5. Monitoring and logging: Enhance logging of HTTP requests made by the PACS server, especially those initiated by cecho.php, and monitor for unusual or unauthorized outbound requests. 6. User awareness: Since user interaction is required, educate staff about phishing or social engineering tactics that might trigger SSRF exploitation. 7. Access controls: Restrict access to the cecho.php functionality to authorized users only, if feasible, or disable it if not essential. 8. Incident response readiness: Prepare to respond to potential SSRF exploitation attempts with forensic capabilities and containment procedures.
