CVE-2025-5481

Status: AnalyzedHigh (7.8)—

Sante DICOM Viewer Pro DCM File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sante DICOM Viewer Pro. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of DCM files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26168.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector CVSS con UI:R (interacción requerida) + descripción explícita de apertura de archivo DCM malicioso indica ejecución en cliente (T1203). El out-of-bounds write permite ejecución arbitraria de código (T1059).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.

Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en las instalaciones afectadas de Sante DICOM Viewer Pro. Para explotar esta vulnerabilidad, se requiere la interacción del usuario, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica se encuentra en el análisis de archivos DCM. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar una escritura posterior al final de un objeto asignado.
