This allows a malicious attacker to craft a URL with a long domain name, e.g. www.safe.opera.com.attacker.com. With the URL being left-aligned, the user will only see the front part (e.g. www.safe.opera.com…) The exact amount depends on the phone screen size but the attacker can craft a number of different domains and target different phones. Starting with version 53.1 Opera Mini displays long URLs with the top-level domain label aligned to the right of the address field which mitigates the issue."},{"lang":"es","value":"Opera Mini para Android versiones por debajo de 53.1, muestra la URL alineada a la izquierda en el campo de dirección. Esto permite a un atacante malicioso crear una URL con un nombre de dominio largo, por ejemplo, www.safe.opera.com.attacker.com. Con la URL alineada a la izquierda, el usuario solo verá la parte frontal (por ejemplo, www.safe.opera.com ...) La cantidad exacta depende del tamaño de la pantalla del teléfono, pero el atacante puede crear varios dominios diferentes y apuntar a diferentes teléfonos . A partir de la versión 53.1, Opera Mini muestra URL largas con la etiqueta de dominio de nivel superior alineada a la derecha del campo de dirección, lo que mitiga el problema"}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:L/Au:N/C:N/I:P/A:N","baseScore":5.0,"accessVector":"NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"PARTIAL","availabilityImpact":"NONE"},"baseSeverity":"MEDIUM","exploitabilityScore":10.0,"impactScore":2.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-Other"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:opera:opera_mini:*:*:*:*:*:android:*:*","versionEndExcluding":"53.1","matchCriteriaId":"EA9B517F-93FF-4082-8F4E-622860AC3668"}]}]}],"references":[{"url":"https://security.opera.com/address-bar-spoofing-in-opera-mini-opera-security-advisories/","source":"security@opera.com","tags":["Vendor Advisory"]},{"url":"https://security.opera.com/address-bar-spoofing-in-opera-mini-opera-security-advisories/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
