An OS command injection vulnerability within the update functionality may allow an authenticated administrator to execute unauthorized arbitrary OS commands. Users with administrative privileges may upload update packages to upgrade the versions of Nozomi Networks Guardian and CMC. While these updates are signed and their signatures are validated prior to installation, an improper signature validation check has been identified. This issue could potentially enable users to execute commands remotely on the appliance, thereby impacting confidentiality, integrity, and availability.
Solution:
Workaround:
The product 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.
