CVE-2024-6468

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.

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.

Fixed in Vault and Vault Enterprise 1.17.2, 1.16.6, and 1.15.12

CVE-2024-6468 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.16.3, 1.17.2, 1.15.12); upgrading removes the vulnerable code path.

1. What is CVE-2024-6468? CVE-2024-6468 is a high-severity security vulnerability in github.com/hashicorp/vault (go), affecting versions >= 1.16.0-rc1, < 1.16.3. It is fixed in 1.16.3, 1.17.2, 1.15.12.
2. How severe is CVE-2024-6468? CVE-2024-6468 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of github.com/hashicorp/vault are affected by CVE-2024-6468? github.com/hashicorp/vault (go) versions >= 1.16.0-rc1, < 1.16.3 is affected.
4. Is there a fix for CVE-2024-6468? Yes. CVE-2024-6468 is fixed in 1.16.3, 1.17.2, 1.15.12. Upgrade to this version or later.
5. Is CVE-2024-6468 exploitable, and should I be worried? Whether CVE-2024-6468 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-6468 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
