Improper verification of the time certificate in Eclipse Cyclone DDS before v0.10.5 allows attackers to bypass certificate checks and execute commands with System privileges.

Improper verification of the time certificate in Eclipse Cyclone DDS before v0.10.5 allows attackers to bypass certificate checks and execute commands with System privileges.

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. Improper verification of the time certificate in Eclipse Cyclone DDS before v0.10.5 allows attackers to bypass certificate checks and execute commands with System privileges.
