DTLS ClientHello Race Conditions In WebRTC Implementations

This white paper, titled “DTLS ‘ClientHello’ Race Conditions in WebRTC Implementations,” details a security vulnerability affecting multiple WebRTC implementations. The research uncovers a security flaw where certain implementations fail to properly verify the origin of DTLS “ClientHello” messages in WebRTC sessions, potentially leading to denial of service attacks. The paper includes methodology, affected systems, and recommendations for mitigation.
