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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Organizations should prioritize updating MedDream PACS Premium to a patched version once the vendor releases a fix. Until then, implement strict input validation and output encoding on all user-supplied data in the modifyTranscript functionality to prevent script injection. Employ web application firewalls (WAFs) with rules designed to detect and block reflected XSS payloads targeting this application. Conduct regular security awareness training for healthcare staff to recognize and avoid phishing attempts involving suspicious URLs. Use Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. Monitor web server logs for unusual URL patterns that may indicate exploitation attempts. Segregate PACS systems from general user networks to limit exposure. Finally, review and enhance incident response plans to quickly address any detected exploitation attempts.

Description

CVE-2025-53707 is a reflected cross-site scripting (XSS) vulnerability in MedDream PACS Premium version 7.3.6.870, specifically in the modifyTranscript functionality. An attacker can craft a malicious URL that, when visited by a user, executes arbitrary JavaScript code in the victim's browser. This vulnerability requires user interaction (clicking the malicious link) but does not require authentication. The CVSS score is 6.1 (medium severity), reflecting limited confidentiality and integrity impact but no availability impact. No known exploits are currently reported in the wild. European healthcare organizations using this PACS software are at risk of targeted phishing or social engineering attacks leveraging this XSS flaw.

Impact

For European organizations, particularly healthcare providers using MedDream PACS Premium, this vulnerability could lead to unauthorized disclosure of sensitive patient information or session hijacking through browser-based attacks. Although the vulnerability does not directly impact system availability, successful exploitation could undermine trust in healthcare IT systems and lead to regulatory compliance issues under GDPR due to potential data leakage. Attackers could use social engineering to trick medical staff into clicking malicious links, enabling them to execute scripts that steal authentication tokens or manipulate displayed data. This could disrupt clinical workflows or lead to incorrect medical decisions if data integrity is compromised. The impact is heightened in Europe due to stringent data protection laws and the critical nature of healthcare services. Additionally, the cross-site scripting vulnerability could serve as an entry point for more complex attacks, including lateral movement within hospital networks or deployment of further malware.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
