An update released by Siemens for its RUGGEDCOM network management system (NMS) patches a couple of cross-site request forgery (CSRF) and cross-site scripting (XSS) vulnerabilities.
Used in various sectors worldwide, the RUGGEDCOM NMS allows organizations to monitor, configure and maintain their RUGGEDCOM mission-critical networks.
According to advisories published by Siemens and ICS-CERT, the product is affected by flaws that may allow a remote attacker to perform administrative operations.
The CSRF vulnerability, tracked as CVE-2017-2682 and assigned a CVSS score of 8.8, affects the product’s web interface and it can be exploited to get an authenticated user to execute various commands on behalf of the attacker. The attacker needs to trick the targeted user into clicking on a specially crafted link.
The XSS flaw, identified as CVE-2017-2683 and assigned a CVSS score of 6.3, could allow a non-privileged attacker to obtain administrative permissions by getting a user to click on a malicious link.

ICS-CERT said there was no evidence that the flaws had been exploited for malicious purposes.
