CVE-2026-67248

A stack-based buffer overflow vulnerability was found in the File Explorer on the ADM. The vulnerability occurs because user-controlled input is not properly validated before being decoded and copied into a fixed-size stack buffer. An authenticated attacker can exploit this issue to cause denial of service of the affected CGI process. Further impact may be possible depending on exploitability and runtime protections. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.

Summary		(es) Una vulnerabilidad de desbordamiento de búfer basado en pila fue encontrada en el Explorador de Archivos en el ADM. La vulnerabilidad ocurre porque la entrada controlada por el usuario no es validada correctamente antes de ser decodificada y copiada en un búfer de pila de tamaño fijo. Un atacante autenticado puede explotar este problema para causar denegación de servicio del proceso CGI afectado. Mayor impacto puede ser posible dependiendo de la explotabilidad y las protecciones en tiempo de ejecución. Los productos y versiones afectados incluyen: desde ADM 4.1.0 hasta ADM 4.3.3.RUN1 así como desde ADM 5.0.0 hasta ADM 5.1.3.RI81.
