The admin login session cookie is insecurely generated making admin session hijacking possible. When an admin logs in, a session cookie is generated using the time of day rounded to 10ms. Since the web server returns its current time of day in responses, it is possible to step backward through possible session values until a working one is found. Once a working session ID is found, an attacker then has admin control of the device and can add a secondary SSID to create a backdoor to the network."}, {"lang": "es", "value": "Se ha descubierto un problema en dispositivos Actiontec WCB6200Q anteriores a 1.1.10.20a. La cookie de sesi\u00f3n de inicio de sesi\u00f3n de administrador se genera de manera no segura haciendo que sea posible secuestrar la sesi\u00f3n de administrador. Cuando un administrador inicia sesi\u00f3n, se genera una cookie de sesi\u00f3n que marca la hora del d\u00eda con una sensibilidad de 10 milisegundos. Dado que el servidor web devuelve su hora actual en las respuestas, es posible probar posibles valores de sesi\u00f3n hasta que se encuentre uno que funcione. Cuando se encuentre un ID de sesi\u00f3n v\u00e1lido, un atacante podr\u00eda entonces obtener control de administraci\u00f3n del dispositivo y a\u00f1adir un SSID secundario para crear una puerta trasera de la red."}], "lastModified": "2018-06-20T15:38:32.697", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:actiontec:wcb6200q_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8C81A788-8E44-4DD4-BDDD-D715BA862486", "versionEndExcluding": "1.1.10.20a"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:actiontec:wcb6200q:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "9BE7F1EF-C238-49BD-A5A2-F63B491B06F6"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "cve@mitre.org"}
