CVE-2026-4556 (GCVE-0-2026-4556)

Vulnerability from cvelistv5 – Published: 2026-09-28 14:29 – Updated: 2026-09-28 16:22

Title

macOS Exam4 Local Privilege Escalation via Command Injection

Summary

Exam4 is affected by a local privilege escalation vulnerability in the com.extegrity.LogTool privileged helper, which communicates with the application via XPC. The [ConsoleLogHelper copyConsoleIntoFileFromStartDate:] method executes a syslog command using attacker-controlled parameters without proper sanitization, enabling command injection. Successful exploitation allows a local attacker to execute arbitrary commands with root privileges through LaunchSynchronous.

Severity

7.8 (High)
