Summary
Observable Timing Discrepancy (CWE-208) in HBUS devices may allow an attacker with physical access to the device to extract device-specific keys, potentially compromising further site security. This issue affects Command Centre Server versions 9.30 prior to vCR9.30.251028a, 9.20 prior to vCR9.20.251028a, 9.10 prior to vCR9.10.251028a, and all versions of 9.00 and prior.
Risk Assessment
An attacker with physical access to the device could extract device-specific keys, potentially leading to further compromise of site security. This risk is especially relevant in locations with weak physical controls.
Recommendation
Update Command Centre Server to a fixed version (vCR9.30.251028a, vCR9.20.251028a, or vCR9.10.251028a depending on the branch). Restrict physical access to HBUS devices to trusted personnel.
