-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Netragard Security Advisory - Sonexis ConferenceManager - 20120201 [POSTING NOTICE] If you intend to post this advisory on your web page please create a link back to the original Netragard advisory as the contents of the advisory may change. For more information about Netragard visit: http://www.netragard.com [Advisory Information] Contact : sales@netragard.com Advisory ID : NETRAGARD-20120201 Researcher : Titon Product Name : Sonexis ConferenceManager Product Version : All Versions up to 10.x Vendor Name:Sonexis Technology, Inc. Type of Vulnerability : Authorization Failure, Credential Leak Impact : Network Compromise / Critical Date Discovered : 01/25/2012 Vendor Notified : 01/31/2012 [Product Description] "ConferenceManager plugs right into your current networks, leveraging your existing investments -- no need for costly upgrades or new infrastructure. And, because you own your equipment, you can scale the number and size of your conferences without scaling your costs. Say goodbye to those pay-as-you go subscription costs and say hello to savings as high as 80%" Taken From: http://www.sonexis.com/products/index.asp [Technical Summary] | Vulnerability 1 | The Sonexis ConferenceManager publishes credentials (often domain credentials) to a web page that is accessible without authentication. In many cases these credentials can be used to access otherwise sensitive and restricted resources that include but are not limited to sharepoint, vpn services, etc. | Vulnerability 2 | The Sonexis ConferenceManager database can be downloaded, modified, and uploaded again by anyone. This can result in the theft of audio recordings and potentially sensitive data as well as a compromise of the system. [Technical Details] The Sonexis ConferenceManager fails to properly check and enforce authorization boundaries. Any user that can access the Sonexis ConferenceManager's web interface can access the "settings.asp" page without restriction or authentication. This page provides an attacker with two opportunities which are: | Vulnerability 1 | [1] The settings.asp page discloses sensitive credentials. These credentials vary between installs but seem to fall into three categories which are: - - Domain Credentials (with or without admin privileges) - - System Credentials (local user) - - Not Yet Set (page not yet used?) Netragard discovered this vulnerability during a customer engagement. Netragard was able to use this vulnerability to compromise the customers entire IT infrastructure including the Domain Controller. [2] The settings.asp page allows anyone to download the entire Sonexis ConferenceManager SQL database without authentication. Once downloaded the attacker can modify the database and may be able to upload the modified database back to the Sonexis ConferenceManager. | Vulnerability 2 | [1] The download.asp page is accessible without authentication. This page allows anyone to download the contents of the Sonexis ConferenceManager database. The contents (shown in the exploitation section) include audio recordings, configuration settings, etc. The original file is a zip file that when decompressed produces multiple SQL files. [2] The upload.asp page is accessible without authentication. This page allows anyone to upload a backed up version of the Sonexis ConfrenceManager database to the system. This can be used to compromise the system if an attacker injects a backdoor into the SQL database. Other attacks may be possible with the upload feature. NOTE: An attacker can use search engines like Google, Yahoo, Bing, etc. to identify vulnerable Sonexis ConfrenceManager systems. To demonstrate this Netragard created a Proof of Concept Google scanner and was able to identify the following ConferenceManager versions, each of which is vulnerable. The scanner was limited to a 50 identifications. Number Identified Version Vulnerable - ----------------- ------- ---------- 2 10.0.40 Yes 2 6.1.39 Yes 1 8.0.15 Yes 1 9.1.18 Yes 5 9.2.11 Yes 26 9.3.14 Yes [Proof Of Concept] Exploiting Vulnerability 1 No exploit required. Simply open your favorite web browser and visit your Sonexis ConferenceManager web interface. Then append "/admin/backup/settings.asp" to the URI as shown below. http://<YOUR SONEXIS URL>/admin/backup/settings.asp To extract credentials view the source and search for the following text. INPUT TYPE="text" NAME="uid" value="XXXXX" <-- Username INPUT TYPE="PASSWORD" NAME="pwd" value="XXXXX" <-- Password |Exploiting Vulnerability 2, Download| No exploit or authentication is required to download or upload the Sonexis ConferenceManager database. To download the db you must first install samba. If you are using ubuntu this can be done with a simple "apt-get install samba". Then configure youre "smb.conf" file in the following way: (file is located here: "/etc/samba/smb.conf") [tmp] comment = tmp path = /tmp/smb browseable = yes read only = no guest ok = yes Once samba is configured the Sonexis ConfrenceManager system will allow you to download the database. To begin the download visit the following URL: (No authentication is required) http://<YOUR SONEXIS URL>/admin/backup/download.asp By default the SonexisConfig.dat file is a zip file. You can unzip the contents of the file and you will find the following files after extraction: communities.dat database.bak recorded_audio.dat <-- Potential confidential information telephony.dat timezone.dat uploadinfo.dat Loading these files into a Microsoft SQL database allows you to read, listen to, or otherwise view the contents. |Exploiting Vulnerability 2, Upload| It is also possible to upload a (modified) SonexisConfig.dat file without authentication. To do so, simply visit the following URL: http://<YOUR SONEXIS URL>/admin/backup/upload.asp [Vendor Status and Chronology] 01/25/2012 - Vulnerability discovered during customer engagement 01/26/2012 - Vulnerability confirmed on 9.3.14, 10.0.40 01/31/2012 - Vendor Contacted but no information provided 02/01/2012 - Vendor Responded 02/02/2012 - Netragard identifies Sonexis Customers 02/02/2012 - Netragard Pre-releases advisory to Sonexis customers 02/06/2012 - Vendor Receives Full Details & Creates Fix 02/07/2012 - Vendor Notifies Customers 02/13/2012 - Publication More information on this can be found on Netragard's blog at: http://pentest.snosoft.com/2012/02/13/netragard-uncovers-0-days-in-sonexis-conferencemanager/ [Solution] Apply the vendor supplied patch.
