CVE-2025-59699 is a medium-severity vulnerability affecting entrust nshield_5c_firmware. It was published on December 2, 2025 and has a CVSS 3.1 base score of 6.8 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.8, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7 (patched in 13.6.12 (LTS) and 13.9.0 (STS)), allow a physically proximate attacker to escalate privileges by booting from a USB device with a valid root filesystem. This occurs because of insecure default settings in the Legacy GRUB Bootloader.
Remediation
Check the references section for vendor advisories and patches from entrust. Update nshield_5c_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
