CVE-2020-37010

Estado: AplazadaAlta (8.4)—

BearShare Lite 5.2.5 contains a buffer overflow vulnerability in the Advanced Search keywords input that allows attackers to execute arbitrary code. Attackers can craft a specially designed payload to overwrite the EIP register and execute shellcode by pasting malicious content into the search keywords field.

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 entrada local (AV:L, UI:A) que requiere interacción del usuario (pegar contenido malicioso en campo de búsqueda), permitiendo ejecución arbitraria de código (CWE-120, shellcode, EIP overwrite).

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.
