Overview
The cybersecurity landscape is constantly evolving with new vulnerabilities being discovered in various systems and devices on an almost daily basis. One such vulnerability that has come to light recently is CVE-2025-32877, a critical security flaw identified in COROS PACE 3 devices. This vulnerability affects devices through version 3.0808.0 and can potentially lead to system compromise or data leakage. Given the widespread use of these devices and the severity of the potential impact, this vulnerability presents a significant risk that needs to be urgently addressed.

How the Exploit Works
The vulnerability arises from the way COROS PACE 3 devices identify themselves as devices without input or output capabilities. This results in the use of the Just Works pairing method which does not implement any form of authentication. This lack of authentication allows attackers to carry out machine-in-the-middle attacks, intercepting and possibly altering the communication between the device and the network it’s connected to. Furthermore, this flaw allows attackers to interact with the device via Bluetooth Low Energy (BLE) without requiring prior authorization, potentially leading to unauthorized access and data leakage.
Conceptual Example Code
While the specifics of exploiting this vulnerability would vary based on the attacker’s approach and the specific network environment, a conceptual example might look something like this:
# An attacker could use a Python script to scan for vulnerable devices
import bluetooth
target_name = "COROS PACE 3"
target_address = None
nearby_devices = bluetooth.discover_devices()
for bdaddr in nearby_devices:
if target_name == bluetooth.lookup_name( bdaddr ):
target_address = bdaddr
break
if target_address is not None:
print(f"Found target Bluetooth device with address {target_address}")
else:
print("Could not find target Bluetooth device nearby")This example simply scans for the vulnerable device. An actual exploit would require additional code to interact with the device and manipulate its data or functionality.
Mitigation Guidance
The recommended mitigation for this vulnerability is to apply the vendor-supplied patch. In situations where applying the patch is not immediately feasible, use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These systems can monitor and potentially block suspicious activity, providing a layer of protection until the patch can be applied.
