CVE-2025-53853

Estado: ModificadaCrítica (9.8)—

A heap-based buffer overflow vulnerability exists in the ISHNE parsing functionality of The Biosig Project libbiosig 3.9.0 and Master Branch (35a819fa). A specially crafted ISHNE ECG annotations file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Buffer overflow en funcionalidad de parsing ISHNE accesible remotamente sin autenticación (AV:N/PR:N) ejecutable mediante archivo malicioso, permitiendo ejecución arbitraria de código.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
