CVE-2018-25328

Estado: AplazadaAlta (8.6)—

VX Search 10.6.18 contains a local buffer overflow vulnerability that allows attackers to overwrite the instruction pointer by supplying an oversized string in the directory field. Attackers can craft a malicious input file containing 271 bytes of junk data followed by a return address to execute arbitrary code with application privileges.

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) que permite sobrescribir el puntero de instrucción y ejecutar código arbitrario. CWE-120 confirma overflow de buffer.

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.
