CVE-2023-24012Data Distribution Service (DDS) Chain of Trust (CoT) violation vulnerability in Open DDS
High 8.2
In plain English
A high-severity information exposure in DDS from OpenDDS. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 22% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code.
Official 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 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 PKCS7_verify function used to validate S/MIME signatures.
