Researchers at Cisco Talos have identified nine software vulnerabilities in commonly used metal detectors manufactured by Garrett. The vulnerabilities were detected in Garrett's iC module, which provides network connectivity to two popular walk-through detectors. The module is used to control the detectors remotely and perform real-time monitoring and diagnostics.

The researchers wrote in a blog post, "An attacker could manipulate this module to remotely monitor statistics on the metal detector, such as whether the alarm has been triggered or how many visitors have walked through. They could also make configuration changes, such as altering the sensitivity level of a device, which potentially poses a security risk to users who rely on these metal detectors."

Device users can mitigate the security flaws by updating their iC modules to the latest version of its firmware, Talos says.
