CVE-2016-20045

Estado: AnalizadaAlta (8.6)—

HNB Organizer 1.9.18-10 contains a local buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying an oversized argument to the -rc command-line parameter. Attackers can craft a malicious input string exceeding 108 bytes containing shellcode and a return address to overwrite the stack and achieve code execution.

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 parámetro de línea de comandos permite ejecución arbitraria de código; vector CVSS confirma escalada de privilegios sin interacción del usuario.

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.
