5.6 · MEDIUMOverview
CVE-2021-24033 is a medium-severity vulnerability affecting facebook react-dev-utils. It was published on March 9, 2021 and has a CVSS 3.1 base score of 5.6 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.6, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
react-dev-utils prior to v11.0.4 exposes a function, getProcessForPort, where an input argument is concatenated into a command string to be executed. This function is typically used from react-scripts (in Create React App projects), where the usage is safe. Only when this function is manually invoked with user-provided values (ie: by custom code) is there the potential for command injection. If you're consuming it from react-scripts then this issue does not affect you.
Remediation
Check the references section for vendor advisories and patches from facebook. Update react-dev-utils to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
