Dell Unity, versions prior to 5.4, contains an OS Command Injection Vulnerability in its svc_cifssupport utility. An authenticated attacker could potentially exploit this vulnerability, escaping the restricted shell and execute arbitrary operating system commands with root privileges.
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.
