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: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 8 Nov 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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.

What to do

Upgrade HASOMED Elefant to 24.04.00.

AI-suggested

1. Immediately upgrade HASOMED Elefant to version 24.04.00 or later once available, as this will contain the necessary authentication fixes. 2. Until patching is possible, restrict network access to the FHIR API by implementing strict network segmentation and firewall rules to limit access only to trusted systems and personnel. 3. Deploy network monitoring and intrusion detection systems to identify unusual or unauthorized API queries indicative of exploitation attempts. 4. Enforce strong internal access controls and limit local network access to the Elefant system to essential users only. 5. Conduct regular audits of API access logs to detect anomalous activity. 6. Educate staff about the risks of insider threats and the importance of network security hygiene. 7. Coordinate with HASOMED support for any available interim security advisories or workarounds. 8. Review and enhance overall FHIR API security posture, including implementing authentication and authorization mechanisms if custom integrations are used. 9. Prepare incident response plans specific to potential data breaches involving EHR data.

Description

An unauthenticated attacker with access to the local network of the medical office can query an unprotected Fast Healthcare Interoperability Resources (FHIR) API to get access to sensitive electronic health records (EHR).

Impact

For European organizations, especially healthcare providers using HASOMED Elefant, this vulnerability could lead to unauthorized disclosure of sensitive patient health information, violating GDPR and other data protection regulations. The exposure of EHR data can result in loss of patient privacy, reputational damage, legal penalties, and potential harm to patients if data is misused. Since the attack requires only local network access, any compromise or insider threat within the healthcare network could exploit this vulnerability. This elevates the risk in environments where network segmentation or access controls are weak. The confidentiality breach could undermine trust in healthcare providers and disrupt clinical operations if data integrity concerns arise from subsequent attacks. The lack of authentication on the FHIR API also suggests potential for automated data harvesting if an attacker gains network foothold. Overall, the impact is primarily on confidentiality but with significant regulatory and operational consequences for European healthcare entities.

CWE-306Missing Authentication for Critical Function (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #21OWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
Architecture and Design
Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Architecture and Design
Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment.
