Overview
CVE-2025-41690 is a critical security vulnerability that could potentially allow a low-privileged attacker within Bluetooth range to gain unauthorized access to higher-privilege user passwords. In particular, the attacker could access the password of a Maintenance user by viewing the device’s event log. This vulnerability is significant as it may lead to system compromise or data leakage.
Vulnerability Summary
CVE ID: CVE-2025-41690
Severity: High (7.4 CVSS Score)

How the Exploit Works
An attacker with low-level privileges within Bluetooth range could potentially exploit this vulnerability by accessing the event log of the target device. This log contains the password of the Maintenance user. By viewing this log, the attacker could retrieve the password and use it to authenticate as the Maintenance user. Consequently, the attacker could gain unauthorized access to sensitive configuration settings and modify device parameters.
Conceptual Example Code
While there’s no specific exploit code available for this vulnerability, the concept would be similar to the following pseudocode:
def exploit(target_device):
event_log = target_device.get_event_log()
maint_password = extract_password_from_log(event_log)
if maint_password:
unauthorized_access(maint_password)
In this conceptual example code, we first access the event log of the target device. We then extract the Maintenance user’s password from the log, and if successful, use it to gain unauthorized access.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the vendor patch when it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. Regular monitoring and timely updates of system software can also help prevent potential exploits of this vulnerability.
