AI-suggested

European organizations should immediately upgrade eProsima Fast-DDS to versions 3.4.1, 3.3.1, or 2.6.11 or later to remediate this vulnerability. In addition, network segmentation should be enforced to restrict access to DDS communication ports only to trusted and authenticated devices, minimizing exposure to malicious SPDP packets. Implementing strict input validation and anomaly detection on DDS traffic can help identify and block malformed or tampered DATA Submessages. Monitoring Fast-DDS process health and setting up automated restart mechanisms can reduce downtime in case of unexpected termination. Organizations should also review and harden their DDS security configurations, ensuring that only authorized publishers can send SPDP packets. Finally, conducting regular vulnerability assessments and penetration testing on DDS deployments will help detect similar issues proactively.

Description

Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group ). Prior to versions 3.4.1, 3.3.1, and 2.6.11, when the security mode is enabled, modifying the DATA Submessage within an SPDP packet sent by a publisher causes a heap buffer overflow, resulting in remote termination of Fast-DDS. If the fields of `PID_IDENTITY_TOKEN` or `PID_PERMISSIONS_TOKEN` in the DATA Submessage — specifically by tampering with the `str_size` value read by `readString` (called from `readBinaryProperty`) — are modified, a 32-bit integer overflow can occur, causing `std::vector::resize` to use an attacker-controlled size and quickly trigger heap buffer overflow and remote process term ination. Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.
