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 immediately review access controls to the MedDream PACS configuration interface, restricting it to trusted internal networks and authenticated users only. Implement web application firewall (WAF) rules to detect and block malicious payloads targeting the 'uploaddir' parameter. Until an official patch is released, apply input validation and output encoding on all user-supplied inputs in the config.php functionality to neutralize potentially malicious scripts. Educate users about the risks of clicking unsolicited or suspicious links, especially those purporting to relate to medical imaging systems. Monitor logs for unusual URL requests containing suspicious parameters. Coordinate with MedDream for timely patch deployment once available. Additionally, consider deploying Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the PACS web interface. Regularly audit and update software versions to minimize exposure to known vulnerabilities.

Description

CVE-2025-58090 is a medium severity reflected cross-site scripting (XSS) vulnerability in MedDream PACS Premium version 7.3.6.870, specifically in the config.php functionality affecting the 'uploaddir' parameter. An attacker can craft malicious URLs that, when visited by a user, execute arbitrary JavaScript code in the context of the victim's browser. This vulnerability requires user interaction (clicking the malicious link) but does not require authentication. The impact includes potential theft of session tokens, user impersonation, or redirection to malicious sites. No known exploits are currently reported in the wild. European healthcare organizations using this PACS software are at risk, especially those with direct internet access to the vulnerable interface.

Impact

For European organizations, particularly healthcare providers using MedDream PACS Premium 7.3.6.870, this vulnerability poses a risk of client-side script injection leading to session hijacking, unauthorized actions, or phishing attacks targeting medical staff. Compromise of user sessions could lead to unauthorized access to sensitive patient data or manipulation of medical imaging workflows, undermining data confidentiality and integrity. Although the vulnerability does not directly affect system availability, successful exploitation could facilitate further attacks or data breaches. Given the critical nature of healthcare data and regulatory requirements such as GDPR, exploitation could result in significant legal and reputational consequences. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments where users may be targeted via phishing or malicious links. The vulnerability's presence in a widely used PACS product increases the attack surface within European healthcare institutions, which are often targeted by cyber adversaries due to the sensitivity of their data.

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.
Architecture and Design · Implementation · Attack Surface Reduction
