Overview

Affected versions of this package are vulnerable to Exposure of Data Element to Wrong Session due to p[UD] and guid values in RTPS packets not being encrypted. An attacker can exploit this to forcibly disconnect a Subscriber and deny their attempts to connect. If the attacker then sends the data(p[UD]) packet to the Global Data Space (239.255.0.1:7400) using the Publisher ID, all other Subscribers (Listeners) connected to the Publisher (Talker) will not receive any data and their connection will be disconnected.
