CVE-2023-52365: Out-of-bounds Read Vulnerability in the Smart Activity Recognition Module - Exploit Details, Code Snippet, and References

CVE-2023-52365 is a significant out-of-bounds read vulnerability discovered in the smart activity recognition module utilized in various wearable and smart devices. This security vulnerability presents a significant risk as successful exploitation may cause affected features on these devices to perform abnormally and could potentially compromise user's privacy. In this blog post, we will discuss the details of this vulnerability, provide a code snippet to demonstrate the issue, and offer links to original references for further research.

Exploit Details

The smart activity recognition module is designed to intelligently recognize and track various activities and movements by processing sensor data received from the wearable or smart device. The vulnerability lies in the improper handling of sensor data, specifically within the data processing function. This function, as written, allows an out-of-bounds read, which could lead to abnormal behavior in the activity recognition features. This could potentially lead to the disclosure of sensitive information, or even remote code execution, depending on the specific implementation.

Code Snippet

Here is a simplified code snippet showcasing the vulnerable processing function found within the smart activity recognition module:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void process_sensor_data(char *sensor_data, size_t sensor_data_length) {
    size_t i;
    for (i = ; i < sensor_data_length + 1; i++) {
        // Perform activity recognition processing on sensor_data
        printf("%c", sensor_data[i]);
    }
}

int main() {
    char sensor_data[] = "A string representing sensor data";
    size_t sensor_data_length = strlen(sensor_data);

    process_sensor_data(sensor_data, sensor_data_length);

    return ;
}

In this simplified example, the process_sensor_data function iterates through an array of characters representing the sensor data. The loop's termination condition allows it to continue reading outside the array's boundaries, ultimately causing an out-of-bounds read situation. An attacker could strategically craft sensor data inputs to exploit this vulnerability, thus causing abnormal behavior in the affected devices.
