CVE-2019-15135 : What You Need to Know

In the Object Management Group (OMG) DDS Security 1.1, the handshake procedure transmits unencrypted data regarding a participant's capabilities, even those that are not relevant to the ongoing session. This vulnerability facilitates attackers in uncovering potentially sensitive accessibility details within a Data Distribution Service (DDS) network.

Understanding CVE-2019-15135

The handshake protocol in Object Management Group (OMG) DDS Security 1.1 sends cleartext information about all of the capabilities of a participant (including capabilities inapplicable to the current session), making it easier for attackers to discover potentially sensitive reachability information on a DDS network.

What is CVE-2019-15135?

The vulnerability in OMG DDS Security 1.1 allows attackers to access sensitive accessibility details by exploiting the unencrypted transmission of participant capabilities during the handshake process.

The Impact of CVE-2019-15135

This vulnerability poses a significant risk as it enables malicious actors to gather potentially sensitive information within a DDS network, compromising data confidentiality and network security.

Technical Details of CVE-2019-15135
