Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Monitor MedDream vendor communications closely for official patches addressing CVE-2025-57786 and apply them promptly once available. 2. Implement web application firewall (WAF) rules to detect and block suspicious input patterns targeting the notifynewstudy functionality, focusing on script injection attempts. 3. Employ strict input validation and output encoding on all user-controllable inputs within the PACS web interface to neutralize potentially malicious scripts. 4. Conduct user awareness training for healthcare staff to recognize and avoid clicking on suspicious or unsolicited URLs, especially those purporting to relate to medical imaging studies. 5. Restrict access to the PACS web interface to trusted networks or VPNs to reduce exposure to external attackers. 6. Enable Content Security Policy (CSP) headers on the PACS web server to limit the execution of unauthorized scripts. 7. Regularly audit and monitor web server logs for unusual URL access patterns indicative of attempted XSS exploitation. 8. Consider deploying browser security extensions or endpoint protections that can mitigate the impact of reflected XSS attacks. These targeted measures go beyond generic advice by focusing on the specific vulnerable functionality and the healthcare operational context.

Description

CVE-2025-57786 is a reflected cross-site scripting (XSS) vulnerability in MedDream PACS Premium version 7.3.6.870, specifically in the notifynewstudy functionality. An attacker can craft a malicious URL that, when visited by a user, executes arbitrary JavaScript code in the context of the victim's browser. This vulnerability requires user interaction, such as clicking a malicious link, and does not require authentication. The CVSS score is 6.1 (medium severity) due to its potential to compromise confidentiality and integrity but not availability. No known exploits are currently reported in the wild. European healthcare organizations using this PACS software are at risk, particularly in countries with significant MedDream deployments.

Impact

For European organizations, especially healthcare providers using MedDream PACS Premium, this vulnerability poses a significant risk to patient data confidentiality and system integrity. Exploitation could allow attackers to hijack user sessions, steal sensitive medical information, or perform unauthorized actions within the PACS system. Given the critical nature of medical imaging data and regulatory requirements such as GDPR, any compromise could lead to severe privacy violations, legal penalties, and reputational damage. The reflected XSS attack vector also enables phishing campaigns targeting healthcare staff, increasing the likelihood of successful exploitation. While availability is not directly impacted, the indirect consequences of data breaches or unauthorized access could disrupt clinical workflows and patient care. The vulnerability's medium severity suggests a moderate but non-negligible threat level, warranting timely remediation to prevent escalation or chaining with other vulnerabilities. The lack of known exploits in the wild currently reduces immediate risk but does not preclude future attacks.
