spyata123/cve-2023-3128Python script to detect CVE-2023-3128 authentication bypass in Grafana via Azure AD email claim validation. Checks Azure AD SSO configuration and reports potential vulnerability.
To check if a domain is vulnerable to CVE-2023-3128, which involves an authentication bypass in Grafana due to Azure AD email claim validation, you can use the following Python script:
#!/usr/bin/env python3 import requests import argparse
def check_cve_2023_3128(target_url, verbose=False): """Check for CVE-2023-3128 vulnerability""" session = requests.Session()
# Step 1: Verify Azure AD SSO configuration
try:
response = session.get(
f"{target_url}/login",
allow_redirects=False,
timeout=10
)
azure_ad_configured = any(
"azuread" in location.lower()
for location in response.headers.get('Location', '')
)
if verbose:
print(f"[*] Azure AD SSO configured: {azure_ad_configured}")
except requests.RequestException as e:
if verbose:
print(f"[!] Connection error: {str(e)}")
return False
# Step 2: Attempt authentication bypass (spoofing)
# Note: This requires creating an Azure AD account with the same email as a target Grafana user.
# This step is not automated due to ethical and legal considerations.
if azure_ad_configured:
if verbose:
print("[*] Azure AD SSO is enabled. Vulnerability may be exploitable via email spoofing.")
return True
else:
if verbose:
print("[-] Azure AD SSO not detected or not vulnerable.")
return False
