Description
The Chassis Management Board in Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7, allows a physically proximate attacker to obtain debug access and escalate privileges by bypassing the tamper label and opening the chassis without leaving evidence, and accessing the JTAG connector. This is called F02.
Analysis
The Chassis Management Board in Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7, allows a physically proximate attacker to obtain debug access and escalate privileges by bypassing the tamper label and opening the chassis without leaving evidence, and accessing the JTAG connector. This is called F02.
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).
