Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
An OS Command Injection vulnerability exists in Node.js versions 14.0.x through 14.14.0, 14.15.x through 14.21.0, 16.0.x through 16.12.0, 16.13.x through 16.18.0, and 18.0.x through 18.11.0 due to an insufficient "IsAllowedHost" check that can easily be bypassed because "IsIPAddress" does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks.
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'.
