CVE-2023-24012 Information

Description

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 PKCS7 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 PKCS7_verify function used to validate S/MIME signatures.
