A format string vulnerability exists in the gpsd_report function of BerliOS GPD daemon (gpsd, formerly pygps) versions 1.9.0 through 2.7. The vulnerability is due to improper handling of user-supplied input in syslog calls, where format string specifiers in certain GPS requests are not sanitized. This allows remote attackers to inject format string specifiers, potentially leading to arbitrary code execution.

This repository contains a single Metasploit module (modules/exploits/linux/http/gpsd_format_string.rb) that exploits a format string vulnerability (CVE-2004-1388) in the Berlios GPSD server. The exploit targets multiple versions of GPSD (1.91 through 2.7) and specific Linux distributions (SuSE, Slackware) by sending a specially crafted payload over TCP port 2947, the default GPSD service port. The module allows the attacker to execute arbitrary code on the target system with the privileges of the GPSD process. The payload is customizable and supports standard Metasploit post-exploitation actions. The code is written in Ruby and follows the standard Metasploit module structure, making it easy to use within the framework. No hardcoded IP addresses or URLs are present; the only fingerprintable endpoint is the TCP port 2947 used by GPSD.
