Last modified
CVE-2025-59699 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7, 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.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
