Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2024-6468)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of requests originating from unauthorized IP addresses when the TCP listener option, proxy_protocol_behavior, was set to deny_unauthorized. When receiving a request from a source IP address that was not listed in proxy_protocol_authorized_addrs, the Vault API server would shut down and no longer respond to any HTTP requests, potentially resulting in denial of service.
