Vulnerability from github – Published: 2024-09-28 09:30 – Updated: 2024-09-28 09:30

Details

The specific flaw exists within the handling of base64-encoded data within WebSocket messages. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device.

Was ZDI-CAN-23230
