Descriptions

Advantech R-SeeNet Versions 2.4.17 and prior are vulnerable to a stack-based buffer overflow. An unauthorized attacker can use an outsized filename to overflow the stack buffer and enable remote code execution.

Las versiones 2.4.17 y anteriores de Advantech R-SeeNet son vulnerables a un Desbordamiento del Búfer. Un atacante no autorizado puede utilizar un nombre de archivo de gran tamaño para Desbordamiento del Búfer y permitir la ejecución remota de código.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech R-SeeNet. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the processing of POST requests sent to the out.php endpoint. When processing the filename and path elements, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account.
