Description Preview
A security vulnerability has been identified in FS S3900-24T4S network devices that allows authenticated users with guest-level access to escalate their privileges and reset the administrator password. This vulnerability enables attackers to gain unauthorized administrative control over the affected devices.
Overview
The vulnerability in FS S3900-24T4S devices allows users who have already authenticated with guest credentials to perform unauthorized privilege escalation. Once exploited, attackers can reset the administrator password, effectively gaining complete control over the device configuration and settings. This represents a significant security risk as it bypasses the intended access control mechanisms of the device. Organizations using these devices should consider this a critical security issue as it could lead to network compromise, unauthorized configuration changes, and potential access to sensitive network traffic.
Remediation
To address this vulnerability, organizations should:
- Apply firmware updates provided by FS if available
- Implement network segmentation to restrict access to the management interfaces of these devices
- Monitor for unauthorized access attempts and password reset activities
- Consider implementing additional authentication mechanisms such as RADIUS or TACACS+ if supported
- Restrict physical and network access to these devices to trusted personnel only
- Change default credentials and implement strong password policies
- Contact FS support for specific patch information if not already available
