Descriptions

Delta Electronics CNCSoft-G2 lacks proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. If a target visits a malicious page or opens a malicious file an attacker can leverage this vulnerability to execute code in the context of the current process.

Delta Electronics CNCSoft-G2 carece de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en montón de longitud fija. Si un objetivo visita una página maliciosa o abre un archivo malicioso, un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Electronics CNCSoft-G2. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of DPAX files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
