CyberRota Analysis

AI-Generated

Consul and Consul Enterprise are susceptible to a denial of service vulnerability in their native RPC listener, which allows an authenticated client to deplete server memory before access control list (ACL) authorization is processed. Exploitation of this flaw can occur without a valid ACL token, provided the client successfully completes the internal RPC mTLS handshake. Organizations using affected versions should prioritize patching to versions 2.0.4 or 1.21.18, 1.22.12 to mitigate potential service disruptions.
