Dell OS10 Networking Switches running 10.5.2.x and above contain an OS command injection vulnerability when using remote user authentication. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands and possible system takeover. This is a critical vulnerability as it allows an attacker to cause severe damage. Dell recommends customers to upgrade at the earliest opportunity.
The vulnerability results from improper validation of input data (CWE-20) passed during the remote user authentication process. Insufficient filtering enables injection of malicious system commands (CWE-78), which are then executed by the switch's operating system. The attack requires no prior authentication or user interaction, and the network vector makes it possible to be carried out entirely remotely.
An attacker can execute arbitrary commands at the operating system level of the device, effectively leading to complete takeover of the network switch. The consequence may be a breach of confidentiality, integrity, and availability of the entire network infrastructure based on vulnerable devices.
Dell recommends updating software as soon as possible. Detailed information about available patches is available in Dell security bulletin DSA-2023-124 at: https://www.dell.com/support/kbdoc/en-us/000216584/dsa-2023-124-security-update-for-dell-smartfabric-os10-multiple-vulnerabilities
