IniNet Solutions GmbH’s SCADA Web Server, versions prior to Version 2.02 suffer from the issues.
IniNet Solutions GmbH’s SCADA Web Server is a third-party software used in industrial control system devices. ICS-CERT is working with vendors to identify affected products that incorporate vulnerable versions of SCADA Web Server.

SCADA Web Server deploys across several industries including building automation, according to IniNet Solutions. The product primarily sees use in Europe.
Multiple HTTP request fields end up parsed by a function that does not check destination buffer size, which could allow an attacker to overflow the buffer that may allow remote code execution or a denial-of-service condition.
CVE-2015-1001 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.
In addition, security features could end up evaded when input has been URL encoded that could allow unauthorized file manipulation and deletion.
CVE-2015-1002 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.
Also, external input ends up used to construct paths to files and directories without properly neutralizing special elements within the pathname that could allow an attacker to read arbitrary OS files.
CVE-2015-1003 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.
No known public exploits specifically target these vulnerabilities. However, an attacker with low skill would be able to exploit these vulnerabilities.
