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.","state":0,"publishedAt":"2026-09-28T14:29:41.456+00:00","modifiedAt":"2026-09-28T16:22:26.038+00:00","affected":[{"ecosystem":"Vendor product","name":"com.extegrity.LogTool","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Extegrity\",\n                    \"product\": \"Exam4\",\n                    \"platforms\": [\n                        \"MacOS\",\n                        \"64 bit\"\n                    ],\n                    \"packageName\": \"com.extegrity.LogTool\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"25.12.28.0\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://pentraze.com/vulnerability-reports"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-4556","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-4556","identifiers":["CVE-2026-4556"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
