CWE ID 284


CVE-2023-50257 is a vulnerability found in eProsima Fast DDS, a C++ implementation of the Data Distribution Service standard. This vulnerability allows a malicious attacker to forcibly disconnect a Subscriber and deny connection attempts by sending a disconnect packet to the Global Data Space. This can disrupt data transmission and disconnect Subscribers from the Publisher. The issue arises from the lack of encryption for the data and GUID values used for disconnection between nodes. It is recommended to apply SROS2 and encrypt the disconnection packet to remediate this vulnerability. The potential danger of this vulnerability is high as it can disrupt communication within an organization's network, potentially leading to data loss or service disruption.
