    How the Exploit Works

    CVE-2023-48252 is an improper authorization vulnerability in Bosch Rexroth’s Nexo cordless nutrunner devices. An authenticated remote attacker can send specially crafted HTTP requests to perform actions beyond their authorized access level. This flaw arises due to insufficient access control checks within the device’s web interface, allowing privilege escalation and unauthorized operations.​NVD+3Bosch PSIRT+3Bosch Rexroth Global+3NVD+3Tenable®+3CVE+3

    Conceptual Example Code

    While specific exploit code is not publicly available, a conceptual example of how an attacker might exploit this vulnerability is as follows:​

    POST /api/device/settings HTTP/1.1
    Host: vulnerable-device.local
    Authorization: Basic [Base64EncodedCredentials]
    Content-Type: application/json

    {
    "parameter": "unauthorized_value"
    }

    In this example, an attacker with low-level credentials sends a POST request to modify device settings that should be restricted to higher-privileged users.​
