Vulnerability Assessment

Weakness	CWE CWE-74 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Input neutralization, injection prevention
Impact	Full system compromise — the attacker can execute any command with the privileges of the vulnerable application process. With a CVSS score of 6.3 (MEDIUM), this represents a moderate risk.
Exploit ScenarioDerived	An attacker injects shell metacharacters (;, \|, &&) into a parameter that is passed to a system command, causing additional commands to be executed.
