The N-Central JSESSIONID cookie attribute is not checked against multiple sources such as sourceip, MFA claim, etc. as long as the victim stays logged in within N-Central. To take advantage of this, cookie could be stolen and the JSESSIONID can be captured. On its own this is not a surprising result; low security tools allow the cookie to roam from machine to machine. The JSESSION cookie can then be used on the attackers\u2019 workstation by browsing to the victim\u2019s NCentral server URL and replacing the JSESSIONID attribute value by the captured value. Expected behavior would be to check this against a second source and enforce at least a reauthentication or multi factor request as N-Central is a highly privileged service."}, {"lang": "es", "value": "SolarWinds N-central versiones hasta 2020.1, permite el secuestro de sesiones y requiere la interacci\u00f3n del usuario o acceso f\u00edsico. El atributo de la cookie JSESSIONID de N-Central no se compara con varias fuentes, como sourceip, MFA claim, etc., siempre que la v\u00edctima permanezca conectada dentro de N-Central. Para aprovechar esto, se podr\u00eda robar la cookie y capturar el JSESSIONID. Por s\u00ed solo, este no es un resultado sorprendente; las herramientas de baja seguridad permiten que la cookie se mueva de una m\u00e1quina a otra. La cookie JSESSION se puede usar en la estaci\u00f3n de trabajo de los atacantes navegando hasta la URL del servidor NCentral de la v\u00edctima y reemplazando el valor del atributo JSESSIONID por el valor capturado. El comportamiento esperado ser\u00eda comparar esto con una segunda fuente y hacer cumplir al menos una nueva autenticaci\u00f3n o una petici\u00f3n de m\u00faltiples factores, ya que N-Central es un servicio con muchos privilegios"}], "lastModified": "2020-10-29T22:14:15.537", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:solarwinds:n-central:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5B3A0E0D-1539-4F2F-9541-BBECD11C4038", "versionEndIncluding": "2020.1"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
