| Title | Shanghai Sunfull Automation Co., LTD. HMI1002-ARM Firmware Revision: 2.0.4 Buffer Overflow |
|---|
| Description | The vulnerability arises when the device processes a malformed message, leading to a buffer overflow. This issue is specifically triggered by improper handling of data within the device, causing memory to overflow into adjacent areas designated for protocol data unit handling. As a result, the device generates a response with an erroneous APDU that includes data reflective of the overflowed buffer content. This malfunction indicates a critical flaw in the device’s memory management that could potentially be exploited to alter device operations or extract sensitive information. |
