A vulnerability, which was classified as problematic, has been found in Ekahau Real-Time Location System. This issue affects some unknown functionality of the component Encryption Algorithm. The manipulation with an unknown input leads to a cryptographic issues vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is confidentiality, and integrity. The advisory summarizes:

Ekahau’s real-time location tracking uses battery-powered Wi-Fi tokens to track assets or staff. Signal measurements (RSSI) of the 802.11 based Wi-Fi communication are processed in the Ekahau RTLS software component, which calculates the exact position of the token.

The weakness was released 04/03/2014 by David Gullasch and Max Moser with modzero AG as MZ-14-01 as not defined advisory (Website). It is possible to read the advisory at securityfocus.com. The public release was coordinated with Ekahau. The identification of this vulnerability is CVE-2014-2716 since 04/01/2014. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are unknown but a private exploit is available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK. The advisory points out:

Ekahau's Real-Time Location System to encrypt messages in an insecure fashion. An attacker is able to read and generate arbitrary messages including button events, text/alarm messages or sending reconfiguration events.

A private exploit has been developed by David Gullasch/Max Moser. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 30 days. During that time the estimated underground price was around $0-$5k.

The advisory contains the following remark:

Ekahau should correct their implementation to ensure message confidentiality, authenticity and integrity.
