CVE-2025-0569 is a high-severity denial-of-service vulnerability affecting the Sante PACS Server. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations without requiring authentication. The specific flaw is due to improper validation of user-supplied data within the parsing of DCM files, which can lead to memory corruption. Consequently, attackers may leverage this vulnerability to disrupt services on the system.
The vulnerability has a CVSS score of 7.5, indicating a high severity level that necessitates immediate attention from security teams. Given the nature of the vulnerability, organizations using affected versions of Sante PACS Server should understand the risk to their operations and prioritize patching to mitigate any potential service disruption.
The lack of authentication for exploitation means that any remote attacker can leverage this vulnerability, heightening the urgency for organizations to address it as part of their security practices.
Organizations should prioritize patching immediately.
Vulnerability Details
The official description of CVE-2025-0569 highlights a memory corruption vulnerability during the parsing of DCM files in Sante PACS Server. The vulnerability is classified under CWE-119 and CWE-787, indicating issues related to improper validation and memory management.
The vulnerability was published on January 30, 2025, and has been analyzed by various advisory sources, including the Zero Day Initiative.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, signifying that it has a high availability impact with low attack complexity and no privileges or user interaction required.
Technical Analysis
The root cause of CVE-2025-0569 is the improper handling of user-supplied data during the parsing of DCM files. This lack of validation can result in a memory corruption condition, effectively allowing an attacker to trigger a denial-of-service state on the system. The attack vector is network-based, which means the vulnerability can be exploited remotely.
The attack complexity is low, and no privileges are required for exploitation. Additionally, there is no user interaction needed, making this vulnerability particularly dangerous.
In terms of impacts, the confidentiality and integrity of the system remain unaffected; however, the availability is critically impacted, allowing an attacker to render services unavailable.
Risk & Impact Analysis
The risk to organizations includes potential service disruptions due to the denial-of-service condition that can be triggered remotely without authentication. This vulnerability may have a significant blast radius, affecting any installation of the Sante PACS Server that has not been patched.
Given the CVSS score of 7.5, organizations should assess their security posture and treat the remediation of this vulnerability as a priority. The longer this vulnerability remains unaddressed, the greater the risk of a successful attack that could impact operations.
