Descriptions

Delta Electronics' CNCSoft-B version 1.0.0.4 and DOPSoft versions 4.0.0.82 and prior are vulnerable to stack-based buffer overflow, which could allow an attacker to execute arbitrary code.

CNCSoft-B versión 1.0.0.4 de Delta Electronics y DOPSoft versiones 4.0.0.82 y anteriores son vulnerables al desbordamiento del búfer de memoria, lo que podría permitir a un atacante ejecutar código arbitrario.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Electronics CNCSoft-B. 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 DPA files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
