CVE-2026-27507 in 10G08-0800GSM Network Switch
Summary
by MITRE • 02/24/2026
Binardat 10G08-0800GSM network switch firmware version V300SP10260209 and prior contain hard-coded administrative credentials that cannot be changed by users. Knowledge of these credentials allows full administrative access to the device.

The vulnerability identified as CVE-2026-27507 affects the Binardat 10G08-0800GSM network switch firmware versions up to and including V300SP10260209. This represents a critical security flaw that undermines the fundamental integrity of network device access controls and demonstrates poor security practices in embedded system development. The issue stems from the inclusion of hard-coded administrative credentials within the firmware itself, which violates established security principles and creates a persistent backdoor access mechanism that cannot be remediated through standard configuration changes.
This technical flaw constitutes a direct violation of the principle of least privilege and represents a classic example of insecure credential management as categorized under CWE-798. The presence of hard-coded credentials in firmware creates a permanent vulnerability that exists across all affected versions, regardless of network configuration or user access controls. The credentials cannot be modified or removed by administrators, making this a particularly dangerous vulnerability that persists through device reboots, firmware updates, or complete system resets. This characteristic aligns with ATT&CK technique T1078.004 which describes valid accounts used for persistence and privilege escalation.
The operational impact of this vulnerability is severe and far-reaching within network infrastructure environments. An attacker who discovers these hard-coded credentials gains unrestricted administrative access to the affected switches, enabling complete control over network traffic routing, access control policies, and device configuration parameters. This level of access allows for network reconnaissance, traffic interception, man-in-the-middle attacks, and potential lateral movement throughout the network. The vulnerability affects network security monitoring capabilities as the device can be compromised without detection, undermining the integrity of network security controls and creating a persistent threat vector that can remain undetected for extended periods.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. Organizations should immediately isolate affected switches from production networks and implement network segmentation to limit potential damage. The most effective immediate solution involves disabling the device entirely until a firmware update is available, as the credentials cannot be changed through normal administrative procedures. Network administrators should conduct comprehensive inventory audits to identify all affected devices and implement monitoring for unauthorized access attempts. Additionally, this vulnerability highlights the need for robust firmware security practices including secure credential management, regular security assessments, and adherence to secure development lifecycle principles to prevent similar issues in future deployments.
