A flaw was found in Keylime. The Keylime registrar, since version 7.12.0, does not enforce client-side Transport Layer Security (TLS) authentication. This authentication bypass vulnerability allows unauthenticated clients with network access to perform administrative operations, including listing agents, retrieving public Trusted Platform Module (TPM) data, and deleting agents, by connecting without presenting a client certificate.

GHSA-4jqp-9qjv-57m2Keylime Missing Authentication for Critical Function and Improper Authentication2026-02-06ghsa · osvUS
### Impact The Keylime registrar does not enforce mutual TLS (mTLS) client certificate authentication since version 7.12.0. The registrar's TLS context is configured with `ssl.CERT_OPTIONAL` instead of `ssl.CERT_REQUIRED`, allowing any client to connect to protected API endpoints without presenting a valid client certificate. **Who is impacted:** - All Keylime deployments running versions 7.12.0 through 7.13.0 - Environments where the registrar HTTPS port (default 8891) is network-accessible to untrusted clients **What an attacker can do:** - **List all registered agents** (`GET /v2/agents/`) - enumerate the entire agent inventory - **Retrieve agent details** (`GET /v2/agents/{uuid}`) - obtain public TPM keys, certificates, and network locations (IP/port) of any agent - **Delete any agent** (`DELETE /v2/agents/{uuid}`) - remove agents from the registry, disrupting attestation services Note: The exposed TPM data (EK, AK, certificates) consists of public keys and certificates. Private keys remain protected within TPM hardware. The HMAC secret used for challenge-response validation is stored in the database but is not exposed via the API. **Affected versions:** >= 7.12.0, <= 7.13.0 **Fixed versions:** 7.12.2, >= 7.13.1 ### Patches A patch for the affected released versions is available. It removes the line that override the configuration of `ssl.verify_mode`, leaving the `CERT_REQUIRED` value set by `web_util.init_mtls()`: ```diff diff --git a/keylime/web/base/server.py b/keylime/web/base/server.py index 1d9a9c2..859b23a 100644 --- a/keylime/web/base/server.py +++ b/keylime/web/base/server.py @@ -2,7 +2,6 @@ import asyncio import multiprocessing from abc import ABC, abstractmethod from functools import wraps -from ssl import CERT_OPTIONAL from typing import TYPE_CHECKING, Any, Callable, Optional import tornado @@ -252,7 +251,6 @@ class Server(ABC): self._https_port = config.getint(component, "tls_port", fallback=0) self._max_upload_size = config.getint(component, "max_upload_size", fallback=104857600) self._ssl_ctx = web_util.init_mtls(component) - self._ssl_ctx.verify_mode = CERT_OPTIONAL def _get(self, pattern: str, controller: type["Controller"], action: str, allow_insecure: bool = False) -> None: """Creates a new route to handle incoming GET requests issued for paths which match the given ``` Users should upgrade to the patched version once it is released. ### Workarounds If upgrading is not immediately possible, apply one of the following mitigations: #### 1. Network isolation (Recommended) Restrict access to the registrar HTTPS port (default 8891) using firewall rules to allow only trusted hosts (verifier, tenant): ##### Example using iptables ``` iptables -A INPUT -p tcp --dport 8891 -s <verifier_ip> -j ACCEPT iptables -A INPUT -p tcp --dport 8891 -s <tenant_ip> -j ACCEPT iptables -A INPUT -p tcp --dport 8891 -j DROP ``` #### 2. Reverse proxy with mTLS enforcement Deploy a reverse proxy (nginx, HAProxy) in front of the registrar that enforces client certificate authentication: ##### Example nginx configuration ``` server { listen 8891 ssl; ssl_certificate /path/to/server.crt; ssl_certificate_key /path/to/server.key; ssl_client_certificate /path/to/ca.crt; ssl_verify_client on; # Enforce client certificates location / { proxy_pass https://localhost:8892; # Internal registrar port } } ```

A flaw was found in Keylime. The Keylime registrar, since version 7.12.0, does not enforce client-side Transport Layer Security (TLS) authentication. This authentication bypass vulnerability allows unauthenticated clients with network access to perform administrative operations, including listing agents, retrieving public Trusted Platform Module (TPM) data, and deleting agents, by connecting without presenting a client certificate.
