The Binardat 10G08-0800GSM network switch firmware, version V300SP10260209 and earlier, contains hard-coded administrative credentials that users cannot change. Anyone who learns these credentials can gain full administrative control of the device. The record reports a CVSS score of 9.8, and no confirmed exploitation appears in the sources consulted.
Overview
CVE-2026-27507 describes hard-coded administrative credentials in the Binardat 10G08-0800GSM network switch firmware, version V300SP10260209 and earlier. The CNA is VulnCheck, the record was published on 2026-02-24, and the weakness is classified as CWE-798 (Use of Hard-coded Credentials).
Impact
- The credentials are built into the product and users cannot change them.
- Knowledge of the credentials gives full administrative access to the device.
- The vector in the record is network-reachable (AV:N), requires no privileges (PR:N) and no user interaction (UI:N), with high confidentiality, integrity and availability impact.
- The record reports a CVSS score of 9.8 from VulnCheck and a 9.3 score under a newer CVSS revision.

Remediation and mitigation
- No vendor fix is identified in the sources consulted. Contact Binardat to confirm whether a firmware update or other fix is available.
- Do not expose the switch management interface to untrusted networks. Restrict access to administrative management networks.
- Place affected switches behind segmentation and access controls, and limit which hosts can reach the management service.
- Inventory all devices running V300SP10260209 or earlier, and plan replacement or compensating controls where no fix exists.
- Treat the built-in credentials as compromised for risk assessment purposes, and monitor for any unexpected administrative access.
Detection guidance
- Review management logs for administrative logins from unexpected sources or at unusual times.
- Monitor for unexpected configuration changes, new accounts or changes to device behavior.
- Alert on management-plane traffic reaching switches from outside approved administrative networks.
Limitations of the available information
- The record does not list a fixed version, a patch, or a vendor advisory.
- The sources do not describe how the credentials are stored or what specific administrative functions they expose.
- The sources consulted do not state whether other Binardat models or firmware branches are affected.
- The EPSS and SSVC values are point-in-time data and may change.
