Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
CVE-2022-39327
Summary
Azure CLI is the command-line interface for Microsoft Azure. In versions prior to 2.40.0, Azure CLI contains a vulnerability for potential code injection. Critical scenarios are where a hosting machine runs an Azure CLI command where parameter values have been provided by an external source. The vulnerability is only applicable when the Azure CLI command is run on a Windows machine and with any version of PowerShell and when the parameter value contains the `&` or `|` symbols. If any of these prerequisites are not met, this vulnerability is not applicable. Users should upgrade to version 2.40.0 or greater to receive a mitigation for the vulnerability.

CWE-78 - OS Command Injection
The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
