New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

FATEK Automation Communication Server Versions 1.13 and prior lacks proper validation of user-supplied data, which could result in a stack-based buffer overflow condition and allow an attacker to remotely execute code.
