CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2024-8185 – Vault Vulnerable to Denial of Service When Processing Raft Join Requests
https://notcve.org/view.php?id=CVE-2024-8185
Vault Community and Vault Enterprise (“Vault”) clusters using Vault’s Integrated Storage backend are vulnerable to a denial-of-service (DoS) attack through memory exhaustion through a Raft cluster join API endpoint . An attacker may send a large volume of requests to the endpoint which may cause Vault to consume excessive system memory resources, potentially leading to a crash of the underlying system and the Vault process itself. This vulnerability, CVE-2024-8185, is fixed in Vault Community 1.18.1 and Vault Enterprise 1.18.1, 1.17.8, and 1.16.12. • https://discuss.hashicorp.com/t/hcsec-2024-26-vault-vulnerable-to-denial-of-service-through-memory-exhaustion-when-processing-raft-cluster-join-requests/71047 • CWE-636: Not Failing Securely ('Failing Open') •

A privileged Vault operator with write permissions to the root namespace’s identity endpoint could escalate their own or another user’s privileges to Vault’s root policy. Fixed in Vault Community Edition 1.18.0 and Vault Enterprise 1.18.0, 1.17.7, 1.16.11, and 1.15.16. • https://discuss.hashicorp.com/t/hcsec-2024-21-vault-operators-in-root-namespace-may-elevate-their-privileges/70565 • CWE-266: Incorrect Privilege Assignment •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2024-7594 – Vault SSH Secrets Engine Configuration Did Not Restrict Valid Principals By Default
https://notcve.org/view.php?id=CVE-2024-7594
Vault’s SSH secrets engine did not require the valid_principals list to contain a value by default. If the valid_principals and default_user fields of the SSH secrets engine configuration are not set, an SSH certificate requested by an authorized user to Vault’s SSH secrets engine could be used to authenticate as any user on the host. Fixed in Vault Community Edition 1.17.6, and in Vault Enterprise 1.17.6, 1.16.10, and 1.15.15. • https://discuss.hashicorp.com/t/hcsec-2024-20-vault-ssh-secrets-engine-configuration-did-not-restrict-valid-principals-by-default/70251 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2024-6468 – Vault Vulnerable to Denial of Service When Setting a Proxy Protocol Behavior
https://notcve.org/view.php?id=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. Vault y Vault Enterprise no manejaron adecuadamente las solicitudes originadas en direcciones IP no autorizadas cuando la opción de escucha TCP, proxy_protocol_behavior, estaba configurada en deny_unauthorized. Al recibir una solicitud de una dirección IP de origen que no figuraba en proxy_protocol_authorized_addrs, el servidor API de Vault se cerraba y ya no respondía a ninguna solicitud HTTP, lo que podría provocar una denegación de servicio. Si bien este error también afectó a las versiones de Vault hasta 1.17.1 y 1.16.5, una regresión separada en esas series de versiones no permitió a los operadores de Vault configurar la opción deny_unauthorized, por lo que no permitió que se cumplieran las condiciones para la denegación de servicio. • https://discuss.hashicorp.com/t/hcsec-2024-14-vault-vulnerable-to-denial-of-service-when-setting-a-proxy-protocol-behavior/68518 • CWE-703: Improper Check or Handling of Exceptional Conditions •
CVSS: 2.6EPSS: 0%CPEs: 2EXPL: 0CVE-2024-5798 – Vault Incorrectly Validated JSON Web Tokens (JWT) Audience Claims
https://notcve.org/view.php?id=CVE-2024-5798
Vault and Vault Enterprise did not properly validate the JSON Web Token (JWT) role-bound audience claim when using the Vault JWT auth method. This may have resulted in Vault validating a JWT the audience and role-bound claims do not match, allowing an invalid login to succeed when it should have been rejected. This vulnerability, CVE-2024-5798, was fixed in Vault and Vault Enterprise 1.17.0, 1.16.3, and 1.15.9 Vault y Vault Enterprise no validaron correctamente la reclamación de audiencia vinculada a roles JSON Web Token (JWT) al utilizar el método de autenticación Vault JWT. Esto puede haber provocado que Vault valide un JWT en el que las afirmaciones de audiencia y roles no coinciden, lo que permitió que un inicio de sesión no válido se realizara correctamente cuando debería haber sido rechazado. Esta vulnerabilidad, CVE-2024-5798, se solucionó en Vault y Vault Enterprise 1.17.0, 1.16.3 y 1.15.9. • https://discuss.hashicorp.com/t/hcsec-2024-11-vault-incorrectly-validated-json-web-tokens-jwt-audience-claims/67770 • CWE-285: Improper Authorization •
