Technical ContextAI
Command injection allows an attacker to execute arbitrary OS commands on the host system through a vulnerable application that passes user input to system shells.
RemediationAI
A vendor patch is available — apply it immediately. Avoid passing user input to system commands. Use language-specific APIs instead of shell commands. If unavoidable, use strict input validation and escaping.
