HashiCorp Vault SSH SE valid_principals flaw any host auth (pre-1.17.6)
CVE-2024-7594 Published on September 26, 2024
Vault SSH Secrets Engine Configuration Did Not Restrict Valid Principals By Default
Vaults 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 Vaults 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.
Weakness Type
Incorrect Permission Assignment for Critical Resource
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. When a resource is given a permissions setting that provides access to a wider range of actors than required, it could lead to the exposure of sensitive information, or the modification of that resource by unintended parties. This is especially dangerous when the resource is related to program configuration, execution or sensitive user data.
