CVE-2026-40852
Description
A highly authenticated attacker can alter the config generator injecting a payload into future created configurations. The device is not correctly checking this configuration value before passing it to an system execute leading to code execution. This can result in a total loss of confidentiality, integrity and availability.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A highly authenticated attacker can inject commands via the config generator in mbNET/mbNET.rokey/mbNET.mini, leading to full system compromise.
Vulnerability
A command injection vulnerability exists in the config generator of MB connect line mbNET, mbNET.rokey, and mbNET.mini devices. The device does not properly sanitize configuration values before passing them to a system execute call, allowing a highly authenticated attacker to inject arbitrary payloads into future configurations. Affected versions are detailed in the vendor advisory [1].
Exploitation
An attacker must have high authentication privileges on the device. They can alter the config generator to embed a malicious payload into a configuration value. When the configuration is subsequently processed, the unsanitized value is executed as a system command, resulting in code execution.
Impact
Successful exploitation leads to complete compromise of the device, including total loss of confidentiality, integrity, and availability. The attacker gains full system control.
Mitigation
Apply the firmware updates provided by MB connect line in advisory [1]. No known workarounds are available; updating to the latest firmware is the only mitigation.
