gpsd through release-3.27.5, fixed at commit 4c06658, contains a command injection vulnerability in gpsprof that allows attackers who control the GPS device subtype value to execute arbitrary shell commands by embedding backtick payloads in the gnuplot plot title without proper escaping. The subtype field sourced from a DEVICES JSON log entry or NMEA PGRMT sentence is written into a generated gnuplot program via a set title statement with only double-quote characters escaped, enabling arbitrary shell command execution as the user running gnuplot when the victim renders the generated plot through the gpsprof and gnuplot workflow.

A flaw was found in gpsd, a service application that monitors one or more GPSes or AIS receivers. The gpsprof utility is vulnerable to a command injection. An attacker who can control the GPS device subtype value can embed malicious commands within the gnuplot plot title. When a user processes a specially crafted plot through gpsprof and gnuplot, these embedded commands can be executed, leading to arbitrary code execution on the system.

An attacker can embed malicious commands within the gnuplot plot title by controlling the GPS device subtype value. When a user processes a specially crafted plot through `gpsprof`, these commands execute, leading to arbitrary code execution. Exploitation requires user interaction.
