What is CVE-2023-24012?
CVE-2023-24012 is a high-severity vulnerability in OpenDDS DDS, published on 9 Jan 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
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.
