Technical details
A command injection vulnerability (CWE-78) exists in systeminformation versions before 4.27.11, specifically in the inetChecksite() function. The vulnerability stems from insufficient sanitization of service parameter strings that are passed to shell commands. An attacker with appropriate access to supply parameters to the affected function can inject arbitrary shell metacharacters to execute unauthorized commands on the system. The fix involved implementing proper shell string sanitization. All versions prior to 4.27.11 are affected; users should upgrade immediately.
