The vulnerability is due to the improper detection of content within executable (EXE) files. An attacker could exploit this vulnerability by sending a customized EXE file that is not recognized and blocked by the ESA. A successful exploit could allow an attacker to send email messages that contain malicious executable files to unsuspecting users. Cisco Bug IDs: CSCvh03786."

La vulnerabilidad se debe a la detección incorrecta de contenido en archivos ejecutables (EXE). Un atacante podría explotar esta vulnerabilidad mediante el envío de un archivo EXE personalizado que no sea reconocido y bloqueado por ESA. Su explotación con éxito podría permitir que el atacante envíe mensajes de correo electrónico que contienen archivos ejecutables maliciosos a usuarios incautos. Cisco Bug IDs: CSCvh03786."
