|

|

==================
|

#Product:-
|
||||
==================
|
||||
Sophos Secure Web Appliance is a purpose-built secure web gateway appliance which makes web protection simple. It provides advanced protection from today’s sophisticated web malware with lightning performance that won’t slow users down. You get full control and instant insights over all web activity on your network.
|
||||
|
||||
==================
|
||||
#Vulnerabilities:-
|
||||
==================
|
||||
Session Fixation Vulnerability
|
||||
|
||||
========================
|
||||
#Vulnerability Details:-
|
||||
========================
|
||||
|
||||
#1. Session Fixation Vulnerability (CVE-2017-6412)
|
||||
|
||||
A remote attacker could host a malicious page on his website that makes POST request to the victim’s Sophos Web Appliance to set the Session ID using STYLE parameter. The appliance does not validate if the Session ID sent by user/browser was issued by itself or fixed by an attacker.
|
||||
|
||||
Also, the appliance does not invalidate pre-login Session IDs it issued earlier once user logs in successfully. It continues to use the same pre-login Session ID instead of invalidating it and issuing a new one.
|
||||
|
||||
Note: An attacker would have to guess/know the IP address of the victim's device
|
||||
|
||||
Proof-of-Concept:
|
||||
|
||||
1.Visit the Sophos Login page to obtain pre-auth Session ID.
|
||||
|
||||
2.Host following webpage on attacking machine with the Session ID obtained in #1. It can be changed a little bit.
|
||||
|
||||
<html>
|
||||
<body>
|
||||
<form name="Sophos_Login"action="https://192.168.253.147/index.php?c=login" method="POST" >
|
||||
<input type="hidden" name="STYLE" value="Pre-Auth Session ID">
|
||||
</form>
|
||||
|
||||
<script>
|
||||
window.onload = function(){
|
||||
document.forms['Sophos_Login'].submit()
|
||||
}
|
||||
</script>
|
||||
</body>
|
||||
</html>
|
||||
|
||||
3. Visit the above page another machine.
|
||||
|
||||
4. You will be redirected to the login page, however Session ID will be the same.
|
||||
|
||||
5. Log into the appliance and check the Session ID, it will be the same from #1.

|

|

==================
|

#Product:-
|
||||
==================
|
||||
Trend Micro ‘InterScan Web Security Virtual Appliance (IWSVA)’ is a secure web gateway that combines application control with zero-day exploit detection, advanced anti-malware and ransomware scanning, real-time web reputation, and flexible URL filtering to provide superior Internet threat protection.
|
||||
|
||||
==================
|
||||
#Vulnerabilities:-
|
||||
==================
|
||||
Multiple Incorrect Access Control,Stored Cross Site Scripting, and Sensitive Information Disclosure vulnerabilities
|
||||
|
||||
========================
|
||||
#Vulnerability Details:-
|
||||
========================
|
||||
|
||||
=============================================================================================================================
|
||||
Sensitive Information Disclosure Vulnerability (CVE-2017-6339):-
|
||||
=============================================================================================================================
|
||||
|
||||
Per IWSVA documentation, by default, IWSVA acts as a private Certificate Authority (CA) and dynamically generates digital certificates that are sent to client browsers to complete a secure passage for HTTPS connections. It also allows administrators to upload their own certificates signed by root CA. An attacker with low privileges can download current CA certificate and Private Key (either the default ones or uploaded by administrators) and use those to decrypt HTTPS traffic thus compromising confidentiality.
|
||||
Also, the default Private Key on this appliance is encrypted with very weak and guessable passphrase ‘trend’. If an appliance uses default Certificate and Private Key provided by Trend Micro, an attacker can simply download these and decrypt the Private Key using default passphrase ‘trend’.
|
||||
|
||||
#Proof-of-Concept:
|
||||
|
||||
1. Log into IWSVA web console with least privilege user.
|
||||
2. Send following POST requests:
|
||||
|
||||
Request#1: Download 'get_current_ca_cert.cer'
|
||||
|
||||

|

Multiple Incorrect Access Control Vulnerabilities (CVE-2017-6338):
|
||||
=============================================================================================================================
|
||||
|
||||
#1. Missing functional level access control allows a low privileged user upload HTTPS Decryption Certificate and Private Key:
|
||||
-----------------------------------------------------------------------------------------------------------------------------
|
||||
|
||||
Per IWSVA documentation, by default, IWSVA acts as a private Certificate Authority (CA) and dynamically generates digital certificates that are sent to client browsers to complete a secure passage for HTTPS connections. It also allows administrators to upload their own certificates signed by root CA.
|
||||
An attacker with low privileges can upload new CA certificate and Private Key and use those to decrypt HTTPS traffic thus compromising confidentiality.
|
||||
|
||||
#Proof-of-Concept:
|
||||
|
||||
1. Log into IWSVA web console with least privilege user ‘Test2’.
|
||||
2. Send following POST request:
|
||||
|
||||

3. Above request will delete/remove existing certificates and add new one. To confirm if the certificate and private key were uploaded successfully, log in with Administrator account and download the certificate/key. These should be the ones that you uploaded.
|
||||
|
||||
|
||||
#2. Missing functional level access control allows an authenticated user change FTP access control setting
|
||||
-----------------------------------------------------------------------------------------------------------------------------
|
||||
An attacker with read only rights can change ‘FTP Access Control Settings’ by sending a specially crafted POST request.
|
||||
|
||||
#Proof-of-Concept:
|
||||
|
||||
1.Log into IWSVA web console with least privilege user ‘Auditor’.
|
||||
2.Send following POST request:
|
||||
|
||||
Request#1:
|
||||
|
||||

|
||||
|
||||
3. This enables FTP access.
|
||||
4. Log into IWSVA web console as admin from another browser and check to see if FTP Access Control List has been updated.
|
||||
|
||||
|
||||
|
||||
#3. Missing functional level access control allows an Auditor user create/modify reports
|
||||
-----------------------------------------------------------------------------------------------------------------------------
|
||||
An authenticated, remote attacker with ‘Auditor’ role assigned to him/her, can modify existing reports or create a new one. This user can also exploit the stored cross-site scripting vulnerability mentioned above.
|
||||
|
||||
#Proof-of-Concept:
|
||||
|
||||
1. Log into IWSVA web console with least privilege user ‘Auditor’.
|
||||
2. Send following POST requests:
|
||||
|
||||
