Official description

Dell SmartFabric OS10 Software, version(s) 10.5.4.x, 10.5.5.x, 10.5.6.x, 10.6.0.x, contain(s) an Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Command execution.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

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

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when 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.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
