The device provides UPnP services that are available on port 3480 and can also be accessed via port 80 using the url \"/port_3480\". It seems that the UPnP services provide \"request_image\" as one of the service actions for a normal user to retrieve an image from a camera that is controlled by the controller. It seems that the \"URL\" parameter passed in the query string is not sanitized and is stored on the stack which allows an attacker to overflow the buffer. The function \"LU::Generic_IP_Camera_Manager::REQ_Image\" is activated when the lu_request_image is passed as the \"id\" parameter in query string. This function then calls \"LU::Generic_IP_Camera_Manager::GetUrlFromArguments\" and passes a \"pointer\" to the function where it will be allowed to store the value from the URL parameter. This pointer is passed as the second parameter $a2 to the function \"LU::Generic_IP_Camera_Manager::GetUrlFromArguments\". However, neither the callee or the caller in this case performs a simple length check and as a result an attacker who is able to send more than 1336 characters can easily overflow the values stored on the stack including the $RA value and thus execute code on the device."}, {"lang": "es", "value": "Se detect\u00f3 un problema en los dispositivos VeraEdge versi\u00f3n 1.7.19 y Veralite versi\u00f3n 1.7.481 de Vera. El dispositivo proporciona servicios UPnP que est\u00e1n disponibles en el puerto 3480 y tambi\u00e9n pueden ser accedidos por medio del puerto 80 mediante la url \"/port_3480\". Parece que los servicios UPnP proporcionan \"request_image\" como una de las acciones de servicio para que un usuario normal recupere una imagen de una c\u00e1mara que es controlada por el controlador. Al parecer el par\u00e1metro \"URL\" pasado en la cadena de consulta no est\u00e1 saneado y es almacenado en la pila, lo que permite a un atacante desbordar el b\u00fafer. La funci\u00f3n \"LU::Generic_IP_Camera_Manager::REQ_Image\" se activa cuando lu_request_image se pasa como el par\u00e1metro \"id\" en la cadena de consulta. Esta funci\u00f3n despu\u00e9s llama a \"LU::Generic_IP_Camera_Manager::GetUrlFromArguments\" y pasa un \"pointer\" a la funci\u00f3n donde ser\u00e1 permitido almacenar el valor del par\u00e1metro de URL. Este puntero es pasado como segundo par\u00e1metro $a2 a la funci\u00f3n \"LU::Generic_IP_Camera_Manager::GetUrlFromArguments\". Sin embargo, ni el llamado ni la persona que llama en este caso realizan una comprobaci\u00f3n de longitud simple y, como resultado, un atacante que puede enviar m\u00e1s de 1336 caracteres y puede desbordar f\u00e1cilmente los valores almacenados en la pila, incluyendo el valor de $RA y, por lo tanto, ejecutar el c\u00f3digo en el dispositivo."}], "lastModified": "2019-06-20T13:42:24.763", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:getvera:veraedge_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "49C1D79D-A586-4D41-A10C-1815E6E0D765", "versionEndIncluding": "1.7.19"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:getvera:veraedge:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "0A3D3CAC-84A4-4F14-8FB6-1E6437F8D2C0"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:getvera:veralite_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AC96E7A8-DB6C-47C8-9B33-AE4ED418C70E", "versionEndIncluding": "1.7.481"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:getvera:veralite:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "914728A7-7BA3-4612-A6AA-172B24431947"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "cve@mitre.org"}
