Description¶

Dell Virtual Storage Integrator for VMware vSphere Client, versions prior to 10.11.1.0, contain(s) an OS Command Injection vulnerability in the IAPI component. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the application's underlying operating system with root privileges. Exploitation may lead to a complete system takeover by an attacker. This vulnerability is considered critical as it allows an unauthenticated remote attacker to achieve arbitrary code execution as root, potentially compromising the entire VSI deployment and underlying infrastructure. Dell recommends customers to upgrade at the earliest opportunity.
