An attacker could exploit the hole, which would lead to arbitrary code execution.

ScadaPro is a supervisory control and data acquisition (SCADA) system used in the power generation, oil and gas, pharmaceuticals, and manufacturing sectors. ScadaPro sees use in multiple countries by various third-party distributors, making total deployment difficult to quantify.

Louth, Ireland-based Measuresoft Development Ltd. also has an office in Missouri City, TX.

ScadaPro uses a fixed or controlled search path to find resources, which could allow an unauthorized user to easily locate and exploit one or more locations. An unauthorized user could place a malicious DLL in a directory where it could load before the valid DLL. An attacker must have access to the host file system to exploit this vulnerability.

CVE-2012-1824 is the number assigned to this vulnerability, which has a CVSS v2 base score of 6.

Here is the ScadaPro Server upgrade.

Here is the ScadaPro Client upgrade.
