Descriptions
eProsima Fast DDS (formerly Fast RTPS) is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Even with the application of SROS2, due to the issue where the data (`p[UD]`) and `guid` values used to disconnect between nodes are not encrypted, a vulnerability has been discovered where a malicious attacker can forcibly disconnect a Subscriber and can deny a Subscriber attempting to connect. Afterwards, if the attacker sends the packet for disconnecting, which is data (`p[UD]`), to the Global Data Space (`239.255.0.1:7400`) using the said Publisher ID, all the Subscribers (Listeners) connected to the Publisher (Talker) will not receive any data and their connection will be disconnected. Moreover, if this disconnection packet is sent continuously, the Subscribers (Listeners) trying to connect will not be able to do so. Since the initial commit of the `SecurityManager.cpp` code (`init`, `on_process_handshake`) on Nov 8, 2016, the Disconnect Vulnerability in RTPS Packets Used by SROS2 has been present prior to versions 2.13.0, 2.12.2, 2.11.3, 2.10.3, and 2.6.7.
eProsima Fast DDS (anteriormente Fast RTPS) es una implementación en C++ del estándar del Servicio de distribución de datos del Object Management Group. Incluso con la aplicación de SROS2, debido al problema donde los datos (`p[UD]`) y los valores `guid` utilizados para desconectar entre nodos no están cifrados, se ha descubierto una vulnerabilidad en la que un atacante malintencionado puede desconectar por la fuerza a un suscriptor y puede negarle a un suscriptor que intente conectarse. Posteriormente, si el atacante envía el paquete para desconectarse, que son datos (`p[UD]`), al Espacio de Datos Global (`239.255.0.1:7400`) usando dicho ID de Editor, todos los Suscriptores (Oyentes) conectados al Publicador (Hablador) no recibirá ningún dato y su conexión se desconectará. Además, si este paquete de desconexión se envía continuamente, los suscriptores (Oyentes) que intenten conectarse no podrán hacerlo. Desde el commit inicial del código `SecurityManager.cpp` (`init`, `on_process_handshake`) el 8 de noviembre de 2016, la vulnerabilidad de desconexión en los paquetes RTPS utilizados por SROS2 ha estado presente antes de las versiones 2.13.0, 2.12.2, 2.11.3, 2.10.3 y 2.6.7.
