CVE-2024-6468

Severity CVSS v4.0:
Pending analysis
Type:

Description

Vault and Vault Enterprise did not properly handle 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.<br /> <br /> While this bug also affected versions of Vault up to 1.17.1 and 1.16.5, a separate regression in those release series did not allow Vault operators to configure the deny_unauthorized option, thus not allowing the conditions for the denial of service to occur.<br /> <br /> Fixed in Vault and Vault Enterprise 1.17.2, 1.16.6, and 1.15.12.
