Dell Container Storage Modules: Improper Neutralization of Special Elements used in an OS Command

CVE-2022-34374 is a high-severity improper neutralization of special elements used in an OS command vulnerability in Dell Container Storage Modules from Dell, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.2 as the first without the flaw, so updating Dell Container Storage Modules to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.42% chance of exploitation within 30 days, higher than 73% of scored CVEs.

Official description

Dell Container Storage Modules 1.2 contains an OS command injection in goiscsi and gobrick libraries. A remote authenticated malicious user with low privileges could exploit this vulnerability leading to to execute arbitrary OS commands on the affected system.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command

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 before it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
