Descriptions

Delta Electronics DIAScreen versions prior to 1.1.0 are vulnerable to an out-of-bounds write condition, which may result in a system crash or allow an attacker to remotely execute arbitrary code.

Delta Electronics DIAScreen versiones anteriores a 1.1.0, son vulnerables a una condición de escritura fuera de límites, lo que puede resultar en un bloqueo del sistema o permitir a un atacante una ejecución de código remota arbitrario

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Industrial Automation DIAScreen. 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 XLS files. The issue results from the lack of proper validation of user-supplied data, which can result in a write before the start of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.
