CVE-2019-25733

Estado: AplazadaAlta (8.6)—

NetShareWatcher 1.5.8.0 contains a structured exception handler buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying malicious input. Attackers can craft a payload with overwritten SEH and NSEH pointers through the Restrictions custom filter field to trigger code execution when the Find function is invoked.

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 local (AV:L, PR:N, UI:N) en campo de filtro personalizado; permite ejecución arbitraria de código al invocar la función Find (CWE-120, SEH overflow).

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.
