CVE-2024-28231 affects eProsima Fast DDS, a C++ implementation of the DDS standard. In versions prior to 2.14.0, 2.13.4, 2.12.3, 2.10.4, and 2.6.8, a manipulated RTPS DATA Submessage can trigger an integer overflow during processing of the payload_size field, which is declared as uint32_t. Supplying a negative value such as -1 causes conversion to a large unsigned value (for example, 0xFFFFFFFF), which is then used in a way that leads to a heap buffer overflow. The resulting memory corruption causes the Fast-DDS process to terminate remotely.

This repository provides a proof-of-concept exploit for a heap buffer overflow vulnerability in eProsima Fast DDS (Fast RTPS) version 2.10.3, as used in ROS 2 Iron. The exploit is implemented in Python (src/exploit.py) and leverages the Scapy library to sniff RTPS UDP packets on a specified ROS topic (default '/chatter'). When a suitable message is observed, the script manipulates the RTPS packet to trigger the overflow and sends it back to the target, causing a denial of service (DoS) on the remote subscriber. The repository includes Dockerfiles for both the exploit environment and a vulnerable target environment, as well as a shell script (prepare_exploit.sh) to build and extract the exploit binary. The exploit is network-based and requires a ROS 2 system with publisher and subscriber nodes on different IP addresses, targeting variable-length message types. No hardcoded IP addresses or external URLs are present, but the exploit interacts with the ROS 2 network stack and RTPS protocol.
