Common Weakness Enumeration

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
The software constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

Vulnerability Media Exposure

[GERMAN] Fortinet Produkte: Mehrere Schwachstellen
Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Fortinet FortiManager, Fortinet FortiOS, Fortinet FortiMail, Fortinet FortiClient und Fortinet FortiAnalyzer ausnutzen, um beliebigen Programmcode auszuführen, seine Rechte auszuweiten, Sicherheitsmechanismen zu umgehen, einen Denial of Service herbeizuführen, sowie um Daten offenzulegen und zu manipulieren.
