Product:
Azure IoT SDK
Summary
Binding to an unrestricted ip address in Azure IoT SDK allows an unauthorized attacker to disclose information over a network. This vulnerability can lead to potential data exposure without requiring any user interaction. The impact is classified as medium severity due to the low confidentiality and integrity impacts.
Details
| Severity | Base Score | CVE |
|---|---|---|
| MEDIUM | 6.5 | CVE-2026-21528 |
Exploitation
An attacker can exploit this vulnerability by sending specially crafted network requests to the Azure IoT SDK that is bound to an unrestricted IP address. Since the attack complexity is low and no privileges are required, an unauthorized user can easily access sensitive information transmitted over the network.
Affected Products
- Azure IoT SDK: Vulnerable due to binding to unrestricted IP addresses, allowing unauthorized information disclosure.
Mitigation
To mitigate this vulnerability, it is recommended to restrict the binding of the Azure IoT SDK to specific IP addresses. This will help prevent unauthorized access and information disclosure over the network. Regularly updating the SDK and monitoring network traffic can also enhance security.
