Technical Analysis
The TLS certificate authentication method in Vault and Vault Enterprise failed to correctly validate client certificates if the trusted certificate was a non-CA certificate. This improper validation could enable an attacker to create a malicious certificate that bypasses authentication controls. The issue affects specific versions prior to 1.15.5 and 1.14.10 and has been addressed in those fixed releases.
Potential Impact
An attacker could bypass authentication by exploiting the improper validation of client certificates when Vault is configured with a non-CA trusted certificate. This could lead to unauthorized access to Vault resources.
Mitigation Recommendations
Upgrade Vault to version 1.15.5 or later, or 1.14.10 or later, where this vulnerability has been fixed. No other mitigations are specified.
