Description
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 editing the Legacy GRUB bootloader configuration to start a root shell upon boot of the host OS. This is called F06.
Analysis
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 editing the Legacy GRUB bootloader configuration to start a root shell upon boot of the host OS. This is called F06.
Technical Context
Privilege escalation allows a low-privileged user or process to gain elevated permissions beyond what was originally authorized. This vulnerability is classified as Improper Privilege Management (CWE-269).
Affected Products
Affected products: Entrust Nshield 5C Firmware, Entrust Nshield Hsmi Firmware, Entrust Nshield Connect Xc Base Firmware
Remediation
Apply the principle of least privilege. Keep systems patched. Monitor for suspicious privilege changes. Use mandatory access controls (SELinux, AppArmor).
