Dell Unity, version(s) 5.4 and prior, contain(s) an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to arbitrary command execution as root. Exploitation may lead to a system take over by an attacker. This vulnerability is considered critical as it can be leveraged to completely compromise the operating system. Dell recommends customers to upgrade at the earliest opportunity.
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.
