Vault TLS Cert Auth Bypass (1.15.5/1.14.10)
CVE-2024-2048 Published on March 4, 2024
Vault Cert Auth Method Did Not Correctly Validate Non-CA Certificates
Vault and Vault Enterprise (Vault) TLS certificate auth method did not correctly validate client certificates when configured with a non-CA certificate as trusted certificate. In this configuration, an attacker may be able to craft a malicious certificate that could be used to bypass authentication. Fixed in Vault 1.15.5 and 1.14.10.
Weakness Type
Improper Certificate Validation
The software does not validate, or incorrectly validates, a certificate. When a certificate is invalid or malicious, it might allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client. The software might connect to a malicious host while believing it is a trusted host, or the software might be deceived into accepting spoofed data that appears to originate from a trusted host.
