CVE-2016-20038

Estado: AplazadaAlta (8.6)—

yTree 1.94-1.1 contains a stack-based buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an excessively long argument to the application. Attackers can craft a malicious command-line argument containing shellcode and a return address to overwrite the stack and execute code in the application context.

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) permite ejecución arbitraria de código. La descripción menciona 'shellcode' y ejecución en contexto de aplicación.

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.
