WellinTech reports that these vulnerabilities affect the following products:
• KingSCADA 3.1 and all previous versions
• KingAlarm&Event 2.0.2 and all previous versions
• KingGraphic 3.1 and all previous versions

A remote attacker can exploit these vulnerabilities to acquire the credentials to login to the database as a legitimate user or remotely execute code in the context of the target process.

WellinTech is a software development company specializing in automation and control. Beijing-based WellinTech has branches in the United States, Japan, Singapore, Europe, and Taiwan.

The WellinTech Web site describes KingSCADA as a Windows-based control, monitoring, and data collection application used across several industries including power, water, building automation, mining, and other sectors.

CVE-2013-2826 is the case number assigned to this vulnerability, which has a CVSS v2 base score of 7.5.

By properly setting the ProjectURL property, it is possible for an attacker to download an arbitrary dll file from a remote location and run the code in the dll in the context of the target process.

CVE-2013-2827 is the case number assigned to this vulnerability, which has a CVSS v2 base score of 7.5.
