Persistent XSS vulnerabilities occur when the application stores and retrieves client supplied data without proper handling of dangerous content. This type of XSS vulnerability is exploited by submitting malicious script content to the application which is then retrieved and executed by other application users. The attacker could exploit this to conduct a range of attacks against users of the affected application such as session hijacking, account take over and accessing sensitive data. In this case, the XSS payload can be submitted by any anonymous user, the payload then renders and executes when a WordPress administrator authenticates and accesses the WordPress Dashboard. The injected payload can carry out actions on behalf of the administrator including adding other administrative users and changing application settings. This flaw could be exploited to ultimately provide full control of the affected system to the attacker."},{"lang":"es","value":"El plugin de WordPress \"WPO365 | LOGIN\" (hasta la versión 15.3 inclusive) de wpo365.com es vulnerable a una vulnerabilidad persistente de Cross-Site Scripting (XSS) (también conocida como XSS almacenada o de segundo orden). Las vulnerabilidades XSS persistentes se producen cuando la aplicación almacena y recupera los datos suministrados por el cliente sin gestionar adecuadamente el contenido peligroso. Este tipo de vulnerabilidad XSS se explota enviando contenido de script malicioso a la aplicación que luego es recuperado y ejecutado por otros usuarios de la aplicación. El atacante podría aprovechar esto para realizar una serie de ataques contra los usuarios de la aplicación afectada, como el secuestro de la sesión, la toma de la cuenta y el acceso a datos sensibles. En este caso, la carga útil XSS puede ser enviada por cualquier usuario anónimo, la carga útil entonces se renderiza y ejecuta cuando un administrador de WordPress se autentifica y accede al Dashboard de WordPress. La carga útil inyectada puede llevar a cabo acciones en nombre del administrador, incluyendo la adición de otros usuarios administrativos y el cambio de la configuración de la aplicación. Este fallo podría ser explotado para proporcionar en última instancia el control total del sistema afectado al atacante"}],"metrics":{"cvssMetricV31":[{"source":"info@appcheck-ng.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N","baseScore":9.3,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":5.8},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":2.7}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:M/Au:N/C:N/I:P/A:N","baseScore":4.3,"accessVector":"NETWORK","accessComplexity":"MEDIUM","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"PARTIAL","availabilityImpact":"NONE"},"baseSeverity":"MEDIUM","exploitabilityScore":8.6,"impactScore":2.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":true}]},"weaknesses":[{"source":"info@appcheck-ng.com","type":"Secondary","description":[{"lang":"en","value":"CWE-79"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-79"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:wpo365:wordpress_\\+_azure_ad_\\/_microsoft_office_365:*:*:*:*:*:wordpress:*:*","versionEndIncluding":"15.3","matchCriteriaId":"348A5DEE-85F8-476A-B9EE-231B7B8F8CFC"}]}]}],"references":[{"url":"https://appcheck-ng.com/wordpress-microsoft-office-365-azure-ad-login-persistent-cross-site-scripting/","source":"info@appcheck-ng.com","tags":["Exploit","Third Party Advisory"]},{"url":"https://www.wpo365.com/change-log/","source":"info@appcheck-ng.com","tags":["Release Notes","Vendor Advisory"]},{"url":"https://appcheck-ng.com/wordpress-microsoft-office-365-azure-ad-login-persistent-cross-site-scripting/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Third Party Advisory"]},{"url":"https://www.wpo365.com/change-log/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes","Vendor Advisory"]}]}}]}
