CVE-2025-58088 identifies a reflected cross-site scripting (XSS) vulnerability in MedDream PACS Premium version 7.3.6.870, a medical imaging software widely used for managing and viewing medical images. The vulnerability resides in the config.php script, specifically in the handling of the 'archivedir' parameter. Improper neutralization of input allows attackers to inject malicious JavaScript code via specially crafted URLs. When a user clicks such a URL, the injected script executes in the context of the victim’s browser session, potentially allowing theft of session cookies, manipulation of displayed content, or redirection to malicious sites. The vulnerability does not require authentication but does require user interaction, such as clicking a malicious link. The CVSS v3.1 base score is 6.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but requiring user interaction, and impacting confidentiality and integrity with no impact on availability. No public exploits have been reported yet, but the vulnerability poses a risk to confidentiality and integrity of sensitive medical data and user sessions. The reflected XSS can be leveraged in phishing campaigns targeting healthcare personnel. The vulnerability affects a specific version of MedDream PACS Premium, emphasizing the need for version management and patching. The lack of current patches or exploit code suggests mitigation should focus on input validation, output encoding, and user awareness until vendor fixes are released.

The primary impact of CVE-2025-58088 on European organizations lies in the potential compromise of sensitive medical data confidentiality and integrity. MedDream PACS Premium is used in healthcare environments to manage patient imaging data, which is highly sensitive and subject to strict data protection regulations such as GDPR. Exploitation could allow attackers to hijack user sessions, steal credentials, or manipulate displayed medical information, potentially leading to misdiagnosis or unauthorized data disclosure. The reflected XSS vulnerability could also be used as a vector for delivering further malware or phishing attacks targeting healthcare staff. Given the critical nature of healthcare services, any disruption or data breach could have severe consequences for patient safety and organizational reputation. The requirement for user interaction means social engineering is a likely exploitation method, increasing the risk in environments with less cybersecurity awareness. European healthcare providers with deployments of MedDream PACS Premium 7.3.6.870 are particularly at risk, and the vulnerability could also affect third-party integrations relying on this software. The medium severity score indicates a moderate but non-negligible risk that should be addressed promptly to avoid escalation.

1. Apply vendor patches immediately once they become available for MedDream PACS Premium 7.3.6.870 to remediate the XSS vulnerability. 2. Until patches are released, implement web application firewall (WAF) rules to detect and block malicious payloads targeting the 'archivedir' parameter. 3. Enforce strict input validation and output encoding on all user-controllable inputs, especially URL parameters, to prevent script injection. 4. Conduct user awareness training focused on recognizing phishing attempts and suspicious URLs to reduce the risk of user interaction with malicious links. 5. Review and restrict access to the config.php functionality to trusted users and networks where possible. 6. Monitor web server logs for unusual requests containing suspicious scripts or payloads targeting the vulnerable parameter. 7. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser context. 8. Regularly audit and update all medical software components to ensure they are running supported and patched versions. 9. Coordinate with healthcare IT security teams to integrate vulnerability scanning and penetration testing focused on web application security.
