Researchers have disclosed multiple vulnerabilities impacting Ultra-wideband (UWB) Real-time Locating Systems (RTLS), enabling threat actors to launch adversary-in-the-middle (AitM) attacks and tamper with location data.

“The zero-days found specifically pose a security risk for workers in industrial environments,” cybersecurity firm Nozomi Networks disclosed in a technical write-up last week. “If a threat actor exploits these vulnerabilities, they have the ability to tamper with safety zones designated by RTLS to protect workers in hazardous areas.”

RTLS is used to automatically identify and track the location of objects or people in real-time, usually within a confined indoor area. This is achieved by making use of tags that are attached to assets, which broadcast USB signals to fixed reference points called anchors that then determine their location.

But flaws identified in RTLS solutions – Sewio Indoor Tracking RTLS UWB Wi-Fi Kit and Avalue Renity Artemis Enterprise Kit – meant that they could be weaponized to intercept network packets exchanged between anchors and the central server and stage traffic manipulation attacks.
