CVE-2025-0568 is a high-severity denial-of-service vulnerability found in the SanteSoft Sante PACS Server. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations without requiring authentication. The specific flaw arises from improper validation of user-supplied data during the parsing of DCM files, which can lead to memory corruption.
With a CVSS base score of 7.5, this vulnerability poses a significant risk to organizations leveraging the Sante PACS Server. The high impact on availability means that systems can become inoperable, severely affecting operations. Organizations should prioritize patching to mitigate this risk.
The vulnerability was published on January 30, 2025, and was analyzed thoroughly, confirming the potential for exploitation. Given the lack of required authentication, the window of opportunity for attackers is broad, increasing the urgency for remediation.
Organizations should take this vulnerability seriously and implement the necessary updates and patches as soon as they become available to prevent service disruption.
Vulnerability Details
The vulnerability, identified as CVE-2025-0568, exists within the Sante PACS Server's capability to parse DCM files. The specific flaw is characterized by a memory corruption issue due to the lack of proper validation of user-supplied data. As a result, attackers can exploit this vulnerability to disrupt service.
The vulnerability has been officially classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-787 (Out-of-bounds Write). The critical nature of this vulnerability is underscored by its CVSS score of 7.5, indicating a high severity level.
Sante PACS Server versions prior to 4.0.10 are affected, highlighting the need for users to upgrade promptly to avoid potential exploitation.
Technical Analysis
The root cause of CVE-2025-0568 stems from improper validation of data when parsing DCM files. This oversight allows attackers to exploit the system by sending crafted inputs, leading to memory corruption. The attack vector is network-based, requiring no authentication, which significantly lowers the barrier for exploitation.
The attack complexity is low, as attackers do not need to possess any special privileges or require user interaction to trigger the vulnerability. The impact on availability is high, leading to potential service disruptions for the affected systems.
In summary, the vulnerability can be exploited with minimal effort, emphasizing the importance of prompt remediation efforts.
Risk & Impact Analysis
Risk to organizations includes potential service outages and loss of access to critical systems relying on the Sante PACS Server. The availability impact is rated as high, meaning that if exploited, the system could become completely inoperable.
Organizations must assess their deployment of the Sante PACS Server and prioritize patching this vulnerability as part of their security posture. Given that authentication is not required, the risk of exploitation is significantly heightened, necessitating immediate action.
With the introduction of this vulnerability, organizations should factor in the potential blast radius, especially if the PACS server is integrated into larger healthcare systems. The priority for remediation is high, given the nature of the service affected.
