Technical details
A Missing Authentication for Critical Function (CWE-306) vulnerability exists in several Honeywell Handheld Scanner base stations, including the C1, D1, and A1/B1 models. The flaw allows an unauthenticated attacker within Bluetooth range of the base station to abuse the communication protocol to execute arbitrary system commands on the host machine connected to the scanner. While the CVSS vector provided by the vendor indicates a network attack vector with user interaction, the description specifically highlights the proximity-based Bluetooth vector. Honeywell has released firmware updates to address this issue and recommends immediate upgrades.
