# Exploit Title: Anuko Time Tracker - SQLi (Authenticated)
# Date: 2022-05-03
# Exploit Author: Altelus
# Vendor Homepage: https://www.anuko.com/
# Software Link: https://github.com/anuko/timetracker/tree/0924ef499c2b0833a20c2d180b04fa70c6484b6d
# Version: Anuko Time Tracker 1.20.0.5640
# Tested on: Linux
# CVE : CVE-2022-24707

# An authenticated user can exploit an SQL Injection vulnerability on the Puncher plugin if its enabled.
# User has to start the puncher and stop it but upon stopping an additional parameter 'date' must be passed.
# The 'date' parameter is then injected with SQL payload for leaking database contents.
