CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 0CVE-2023-6337 – Vault May be Vulnerable to a Denial of Service Through Memory Exhaustion When Handling Large HTTP Requests
https://notcve.org/view.php?id=CVE-2023-6337
HashiCorp Vault and Vault Enterprise 1.12.0 and newer are vulnerable to a denial of service through memory exhaustion of the host when handling large unauthenticated and authenticated HTTP requests from a client. Vault will attempt to map the request to memory, resulting in the exhaustion of available memory on the host, which may cause Vault to crash. Fixed in Vault 1.15.4, 1.14.8, 1.13.12. HashiCorp Vault y Vault Enterprise 1.12.0 y versiones posteriores son vulnerables a una denegación de servicio debido al agotamiento de la memoria del host cuando se manejan grandes solicitudes HTTP autenticadas y no autenticadas de un cliente. Vault intentará asignar la solicitud a la memoria, lo que provocará que se agote la memoria disponible en el host, lo que puede provocar que Vault falle. Corregido en Vault 1.15.4, 1.14.8, 1.13.12. • https://discuss.hashicorp.com/t/hcsec-2023-34-vault-vulnerable-to-denial-of-service-through-memory-exhaustion-when-handling-large-http-requests/60741 https://security.netapp.com/advisory/ntap-20240112-0006 • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2023-3775
A Vault Enterprise Sentinel Role Governing Policy created by an operator to restrict access to resources in one namespace can be applied to requests outside in another non-descendant namespace, potentially resulting in denial of service. Fixed in Vault Enterprise 1.15.0, 1.14.4, 1.13.8. Vault Enterprise Sentinel Role Governing Policy creada por un operador para restringir el acceso a los recursos en un espacio de nombres se puede aplicar a solicitudes externas en otro espacio de nombres no descendiente, lo que podría provocar una denegación de servicio. Corregido en Vault Enterprise 1.15.0, 1.14.4, 1.13.8. A flaw was found in the Vault Enterprise. • https://discuss.hashicorp.com/t/hcsec-2023-29-vault-enterprise-s-sentinel-rgp-policies-allowed-for-cross-namespace-denial-of-service/58653 https://access.redhat.com/security/cve/CVE-2023-3775 https://bugzilla.redhat.com/show_bug.cgi?id=2241306 • CWE-20: Improper Input Validation CWE-266: Incorrect Privilege Assignment CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.8EPSS: 0%CPEs: 6EXPL: 0CVE-2023-4680 – Vault's Transit Secrets Engine Allowed Nonce Specified without Convergent Encryption
https://notcve.org/view.php?id=CVE-2023-4680
HashiCorp Vault and Vault Enterprise transit secrets engine allowed authorized users to specify arbitrary nonces, even with convergent encryption disabled. The encrypt endpoint, in combination with an offline attack, could be used to decrypt arbitrary ciphertext and potentially derive the authentication subkey when using transit secrets engine without convergent encryption. Introduced in 1.6.0 and fixed in 1.14.3, 1.13.7, and 1.12.11. El motor de secretos de tránsito de HashiCorp Vault y Vault Enterprise permitió a los usuarios autorizados especificar nonces arbitrarios, incluso con el cifrado convergente deshabilitado. El endpoint de cifrado, en combinación con un ataque fuera de línea, podría usarse para descifrar texto cifrado arbitrario y potencialmente derivar la subclave de autenticación cuando se utiliza el motor de secretos de tránsito sin cifrado convergente. • https://discuss.hashicorp.com/t/hcsec-2023-28-vault-s-transit-secrets-engine-allowed-nonce-specified-without-convergent-encryption/58249 • CWE-20: Improper Input Validation CWE-323: Reusing a Nonce, Key Pair in Encryption •
CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 0CVE-2023-3462 – Vault's LDAP Auth Method Allows for User Enumeration
https://notcve.org/view.php?id=CVE-2023-3462
HashiCorp's Vault and Vault Enterprise are vulnerable to user enumeration when using the LDAP auth method. An attacker may submit requests of existent and non-existent LDAP users and observe the response from Vault to check if the account is valid on the LDAP server. This vulnerability is fixed in Vault 1.14.1 and 1.13.5. A flaw was found in the HashiCorp Vault. The Vault and Vault Enterprise (“Vault”) LDAP auth method allows unauthenticated users to potentially enumerate valid accounts in the configured LDAP system by observing the response error when querying usernames. • https://discuss.hashicorp.com/t/hcsec-2023-24-vaults-ldap-auth-method-allows-for-user-enumeration/56714 https://access.redhat.com/security/cve/CVE-2023-3462 https://bugzilla.redhat.com/show_bug.cgi?id=2228020 • CWE-203: Observable Discrepancy •
