============================================================================================
Manufacturer: Observa Telecom
Model: AW4062
Tested firmwares: 1.3.5.18 and 1.4.2 (latest)
Comments: Common router that Spanish ISP Telefónica used to give away to
their
ADSL customers specially during 2012.
--------------------------------------------------------------------------------------------
----------------------------- Persistent Cross Site Scripting
----------------------------
* Description: Multiple Cross-site Scriptings (XSS) found into the
configuration
menu within the router front-web.
These XSS give an attacker the opportunity to execute malicious
scripts.
* Report status: Reported to MITRE on 2015-03-12. Waiting for assignation.
OSVDB-121211 (http://osvdb.org/show/osvdb/121211)
* PoC:
The threat is found inside some entry inputs that let special characters to
be written in
and show the added information into the web itself.
I.e., there’s a vulnerable input field within the subdirectory Domain
Blocking. When used
legitimately, this input is used to block the traffic between the router
and some particular
domains.
The script will remain stored (persistent XSS) into the field Domain from
the Domain Block
Table and it will be executed each time the victim access to the Domain
Blocking
subdirectory.
This vulnerability can also be found within the input fields that belong to
other
subdirectories like Firewall/URL Blocking, Firewall/Port Forwarding,
Services/DNS/Dynamic
DNS and Advance/SNMP, between others.
The most effective attack is found inside the Advance/SNMP subdirectory. By
injecting the
script into the System Name field, the malicious code will be executed each
time someone
connects to the router because the script is reflected into the home page.
--------------------------------------------------------------------------------------------
------------------------------- Cross Site Request Forgery
-------------------------------
* Description: Every input field is vulnerable to Cross Site Request
Forgery
(CSRF) attacks.
* Report status: Reported to MITRE on 2015-03-12. Waiting for assignation.
OSVDB-121210 (http://osvdb.org/show/osvdb/121210),
OSVDB-121212 (http://osvdb.org/show/osvdb/121212) and
OSVDB-121214 (http://osvdb.org/show/osvdb/121214)
* PoC:
I.e., if an attacker wants the victim to ping a certain IP address in order
to check whether
the victim is already logged into the router, he will send this URL to the
victim:
http://192.168.1.1/goform/formPing?pingAddr=37.252.96.88
It is also possible for an attacker to change the default router password
by sending the
victim this URL:
http://192.168.1.1/goform/formPasswordSetup?userMode=0&oldpass=1234&newpass=12345&confpass=12345&save=%22Apply%20Changes%22
The URL above forces the user with index 0 (it is always going to be the
user named 1234)
to change his default password from 1234 to 12345.
The following URL forces the victim to change his DNS servers to those the
attacker wants to.
http://192.168.1.1/goform/formDNS?dnsMode=dnsManual&dns1=37.252.96.88&dns2=&dns3=
Any action which is available within the website can be attacked through
CSRF.
This includes opening ports, changing the DHCP and NTP servers, modifying
the Wireless
Access point, enabling WPS, etc.
--------------------------------------------------------------------------------------------
---------------------------------- Privilege Escalation
----------------------------------
* Description: Any user without administrator rights is able to carry out a
privilege escalation by reading the public router configuration
file (config.xml). This file stores each of the router configuration
parameters, including the credentials from all users in plain text.
* Report status: Reported to MITRE on 2015-03-12. Waiting for assignation.
OSVDB-121213 (http://osvdb.org/show/osvdb/121213) and
OSVDB-121285 (http://osvdb.org/show/osvdb/121285)
* PoC:
An user without administrator rights (i.e., user), connects to the router
through FTP.
This user is able to get both /etc/passwd and config.xml files.
The file config.xml stores each of the router configuration parameters in
plain text,
including the credentials from all users.
Doing so, any user is able to gain administrator privileges.
This is critical because not too many people know there is another user
apart from the
administrator one. That means they only change the administrator password,
leaving a
default user with default credentials (user:user) being able to escalate
privileges.
--------------------------------------------------------------------------------------------
------------------------------------ Denial of Service
-----------------------------------
* Description: An attacker is able to carry out an external Denial of
Service
attack
* Report status: Reported to MITRE on 2015-03-12. Waiting for assignation.
* PoC:
It is possible for an attacker to carry out a Denial of Service attack
through CSRF:
http://192.168.1.1/goform/admin/formReboot
If a victim opens this URL, router commits all the information and reboots
in a process
that takes 60 seconds long.
There are tons of ways for an attacker to do a Denial of Service attack by
exploiting
Cross Site Request Forgery vulnerabilities:
a) Establish new firewall rules in order to block certain URLs, IPs or
MACs. Even setting
up a global Deny order is possible and only allowing traffic from/to
certain IPs/MAcs.
b) Delete the router configuration that allows itself to connect to the
Internet Service
Provider.
c) Disable the Wireless Interface so no device can be connected through the
802.11 protocol.
d) Etc.

----------------------------- Persistent Cross Site Scripting
----------------------------
* Description: Some input fields within the router website are vulnerable
to
Cross-site Scripting (XSS) attacks, allowing an attacker to execute
malicious code.
* Report status: Reported to MITRE on 2015-03-12. Waiting for assignation.
OSVDB-121218 (http://osvdb.org/show/osvdb/121218)
* PoC:
Despite the fact that most of the input fields do not allow special
characters to be
written in, there are still some of them in which a XSS can be performed.
I.e., the SSID field within the Wireless>Basic subdirectory allows script
code injection.
The script execution can be clearly seen within the
Wireless>Security and Wireless>MAC Filter subdirectories.
--------------------------------------------------------------------------------------------
------------------------------- Cross Site Request Forgery
-------------------------------
* Description: Multiple Cross Site Request Forgery (CSRF) vulnerabilities
within
the router website allow an external attacker to carry out actions
such as changing the administrator password.
* Report status: Reported to MITRE on 2015-03-12. Waiting for assignation.
OSVDB-121216 (http://osvdb.org/show/osvdb/121216) and
OSVDB-121217 (http://osvdb.org/show/osvdb/121217)
* PoC:
Every input field is vulnerable to CSRF.
Whenever the administrator user changes his password, he is actually
opening the URL:
/password.cgi?adminPassword=newpassword.
An attacker may send the following URL to the victim, so the administrator
password will
be changed to 1234567890:
http://192.168.1.1/password.cgi?adminPassword=1234567890
If an attacker wants to change the DNS servers, he may use the following
URL to do so once
the victim opens the link:
http://192.168.1.1/dnscfg.cgi?dnsPrimary=37.252.96.88&dnsSecondary=37.252.96.89&dnsIfc=&dnsRefresh=1
--------------------------------------------------------------------------------------------
-------------------------------- Universal Plug and Play
---------------------------------
* Description: An unauthenticated attacker is able to modify firewall rules
and
carry out a persistent denial of service by using the supported
Universal Plug and Play protocol.
* Report status: Reported to MITRE on 2015-05-21. Waiting for assignation.
OSVDB-122383 (http://osvdb.org/show/osvdb/122383)
* PoC:
The Universal Plug and Play (UPnP) protocol is supported by the device.
This protocol has
lots of weaknesses, such as the lack of an authentication process, which
can be exploited
by attackers.
The device supports multiple UPnP actions, such as changing the firewall
rules
(AddPortMapping) or the termination of any WAN connections
(ForceTermination).
These actions allow an attacker to carry out a persistent denial of service
(router needs
to be factory reset to work properly again) or open critical ports, even
for remote hosts
which are not into the LAN.

* PoC:
I.e., if an attacker wants to change the DNS servers, he may use the
following URL to do so
once the victim opens the link:
http://192.168.1.1/form2Dns.cgi?dnsMode="1"&dns1="37.252.96.88"&dns2="37.252.96.89"&dns3=""&submit.htm?dns.htm="Send"&save="Aplicar
cambios"
It is also possible for an attacker to change the default router
administrator password by
sending the victim this URL:
http://192.168.1.1/form2userconfig.cgi?
username="1234"&privilege=2&oldpass="1234"&newpass="newpass"&confpass="newpass"&modify="Modificar"&select="s0"&hiddenpass="1234"&submit.htm?userconfig.htm="Send"
The URL above forces the administrator user (it is always going to be the
user named 1234)
to change his default password from 1234 to newpass.

The Universal Plug and Play (UPnP) protocol is supported by the device.
This protocol has
lots of weaknesses, such as the lack of an authentication process, which
can be exploited
by attackers.
The device supports multiple UPnP actions, such as changing the firewall
rules
(AddPortMapping) or the termination of any WAN connections
(ForceTermination).
These actions allow an attacker to carry out a persistent denial of service
(router needs
to be factory reset to work properly again) or open critical ports, even
for remote hosts
which are not into the LAN.
It is also possible for an attacker to change the WPS configuration
settings, reset the AP
to the default ones and obtain critical information, such as WLAN passwords.

Despite the fact that most of the input fields do not allow special
characters to be
written in, there are still some of them in which a XSS can be performed.
I.e., the SSID field within the Wireless->Basic subdirectory allows script
code injection.
The script execution can be clearly seen within Wireless->Security and
Wireless->MAC Filter
subdirectories.
