    Below is a conceptual example of how an HTTP request might be manipulated to exploit this vulnerability:

    GET /api/v1/credentials HTTP/1.1
    Host: target.example.com
    Authorization: Bearer low-privileged-token
    {
    "request": "retrieve",
    "params": {
    "type": "manufacturer"
    }
    }

    In this example, the attacker uses a low-privileged token to request the manufacturer’s credentials. This should not be possible under normal circumstances, but due to the vulnerability, the system fails to properly validate the privilege level of the request.
    This is a conceptual example and the actual exploit may involve additional steps or different parameters depending on the specific implementation of the charge controller and its API.

  • CVE-2025-59033: Critical Vulnerability in Microsoft’s Driver Block List

    Overview

    The world of Cybersecurity is once again on high alert due to a new vulnerability, CVE-2025-59033, discovered within Microsoft’s driver block list.

    Windows 11 | All versions without HVCI
    Windows Server | 2016 and later versions without HVCI

    How the Exploit Works

    The exploit takes advantage of a flaw in the WDAC policy implementation. On systems that do not have HVCI enabled, entries that specify only the to-be-signed (TBS) part of the code signer certificate are blocked correctly. However, entries that incorporate the signing certificate’s TBS hash along with a ‘FileAttribRef’ qualifier (such as file name or version) will not be blocked. This loophole allows potential attackers to bypass the driver blocklist, potentially leading to a system compromise or data leakage.

    Conceptual Example Code

    The following pseudocode demonstrates a conceptual exploit for this vulnerability:

    def exploit(target_system):
    malicious_driver = {
    'tbs_hash': '...',
    'FileAttribRef': {
    'file_name': '...',
    'version': '...'
    }
    }
    if not target_system.has_hvci_enabled():
    upload_driver(target_system, malicious_driver)
    target_system.install_driver(malicious_driver)
    compromise_system(target_system)

    This pseudocode illustrates an attacker creating a malicious driver with a TBS hash and a ‘FileAttribRef’ qualifier, then checking if the target system has HVCI enabled. If HVCI is not enabled, the attacker then uploads and installs the malicious driver, compromising the system. This example highlights the potential severity of this vulnerability and the importance of enabling HVCI or applying the vendor’s patch.
