Cohesive Networks VNS3 Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Cohesive Networks VNS3. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the web service, which listens on TCP port 8000 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-24176.

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.
