Overview
In the ever-evolving world of cybersecurity, a new vulnerability has been discovered that puts users of the COROS PACE 3 at risk. This vulnerability, identified as CVE-2025-48706, could potentially allow an attacker to compromise the system or leak sensitive data. It is significantly critical due to the high CVSS Severity Score of 9.1, indicating a major potential impact on the affected device.
The vulnerability is embedded in COROS PACE 3 through 3.0808.0, making all users of these versions potential targets. The risk stems from an out-of-bounds read vulnerability, which, when exploited, forces the device to reboot. This eventuality matters because it could lead to data loss, interruptions in service, and potential system compromise.

How the Exploit Works
The exploit takes advantage of an out-of-bounds read vulnerability in the COROS PACE 3. An attacker can send a specially crafted Bluetooth Low Energy (BLE) message to the device. This message triggers the vulnerability, causing the device to access memory outside of its intended boundary, leading to a forced reboot. The reboot may disrupt the system’s operations and could potentially allow an attacker to compromise the system or leak data.
Conceptual Example Code
Although we won’t provide a specific exploit code for ethical reasons, a conceptual example would involve an attacker crafting a malicious BLE packet. This packet would include data that causes the device to read beyond its memory boundary. Below is a simplified pseudo-code representation:
# Pseudo code for a malicious BLE packet
class BLEPacket:
def __init__(self, payload):
self.payload = payload
malicious_payload = bytes([0x00]*1001) # The device can only safely handle 1000 bytes
packet = BLEPacket(malicious_payload)
device.send(packet)In the above pseudo-code, the attacker creates a malicious `BLEPacket` with a payload that exceeds the device’s memory boundary, causing an out-of-bounds read and forcing a system reboot.
