CVE-2023-24010: Data Distribution Service (DDS) Chain of Trust (CoT) violation in Fast DDS

Published Jan 9, 2025

Updated

An attacker can arbitrarily craft malicious DDS Participants (or ROS 2 Nodes) with valid certificates to compromise and get full control of the attacked secure DDS databus system by exploiting vulnerable attributes in the configuration of PKCS#7 certificate’s validation. This is caused by a non-compliant implementation of permission document verification used by some DDS vendors. Specifically, an improper use of the OpenSSL PKCS7verify function used to validate S/MIME signatures.

Remediation

Information

Instead of including the Permission CA into the store of trusted certificates to use for chain verification, the Permission CA (and only the Permission CA) should be included in the set of certificates in which to search for signer's certificates. The store of trusted certificates to use for chain verification should then also be set to null. 2) With the store of trusted certificates to use for chain verification set to null, the PKCS7_NOVERIFY flag should then be enabled so any signer's certificates (i.e. only the Permission CA) is not chain verified. 3) Given that only a valid signer's certificate must be the Permission CA, the PKCS7_NOINTERN flag should then be enabled so any set of certificates in the message itself are not searched when locating the signer's certificates.
