VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2024-13089

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.
