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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 13 Dec 2025
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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

To mitigate CVE-2025-14607, organizations should immediately upgrade all instances of OFFIS DCMTK to version 3.7.0 or later, which contains the official patch for this vulnerability. In addition, network-level protections should be implemented to restrict access to DICOM services only to trusted and authenticated users and systems, reducing exposure to remote attacks. Employing application-layer firewalls or DICOM-aware security gateways can help detect and block malformed DICOM data that might trigger the vulnerability. Regularly audit and monitor logs for unusual activity or crashes related to DICOM processing. For environments where immediate upgrade is not feasible, consider isolating vulnerable systems from untrusted networks and applying strict network segmentation. Finally, maintain an incident response plan tailored to healthcare IT environments to quickly address potential exploitation attempts.

Description

A vulnerability was detected in OFFIS DCMTK up to 3.6.9. Affected by this issue is the function DcmByteString::makeDicomByteString of the file dcmdata/libsrc/dcbytstr.cc of the component dcmdata. The manipulation results in memory corruption. The attack can be launched remotely. Upgrading to version 3.7.0 can resolve this issue. The patch is identified as 4c0e5c10079392c594d6a7abd95dd78ac0aa556a. You should upgrade the affected component.

Impact

The primary impact of CVE-2025-14607 is the potential for remote attackers to cause memory corruption in applications using vulnerable DCMTK versions, which can lead to denial of service through application crashes or potentially arbitrary code execution if exploited further. This can disrupt medical imaging workflows, delay diagnosis and treatment, and compromise patient care. Confidentiality and integrity impacts are limited but cannot be fully ruled out if an attacker achieves code execution. The vulnerability affects a critical component in healthcare IT infrastructure, increasing the risk to hospitals, clinics, and medical device manufacturers relying on DCMTK for DICOM processing. The medium CVSS score reflects moderate risk, but the healthcare sector's sensitivity elevates the operational impact. Organizations worldwide that integrate DCMTK into their imaging systems or PACS (Picture Archiving and Communication Systems) are at risk of service disruption and potential security breaches if unpatched.
