eProsima Fast DDS versions prior to 2.4.0 (#2269) are susceptible to exploitation when an attacker sends a specially crafted packet to flood a target device with unwanted traffic, which may result in a denial-of-service condition and information exposure.

Weakness

The product does not sufficiently monitor or control transmitted network traffic volume, so that an actor can cause the product to transmit more traffic than should be allowed for that actor.

Fast_dds Eprosima * 2.4.0 (excluding)
