Serialization And Deserialization Vulnerability

On April 4th of this year, Microsoft issued security bulletin MS15-034; this security bulletin explains a vulnerability that “could allow remote code execution if an attacker sends a specially crafted HTTP request to an affected Windows system.” Later, on June 9th, Microsoft issued another security bulletin, MS15-056; this security bulletin explains a vulnerability that “could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who

Process Hollowing – a new instance of a legitimate process is launched and memory that contains original code is promptly deallocated (hollowed) and replaced with malicious code

The attack is carried out on a closed environment using a local web server to host the

Which tool and application were used to exploit the identified vulnerability on the targeted Microsoft® Windows 2003 XP server?

For the actual attack that took place there are changes that need to be performed on both the client's side as well as the server's side. These changes involve limiting the quantities of request either side can make. For the client's I would recommend a firewall placed between them and the server which would be configured to limit the amount of requests to be made to any outside source and either notify and administrator or outright blocking additional requests beyond the threshold.

The first case will require blocking, using the firewall, any outbound traffic initiated from within the network directed to unknown hosts. Resetting passwords for all the accounts, changing encryption keys and installing Intrusion Detection and Prevention at the host level will also help to deal with seeds left behind by the intruders.

To address vulnerability plugin 106800 / KB4074594 Cumulative Update, the Web Developer obtained and installed this on servers: ReportsPW1, GTN-WDS-APP-P01, EGTN-DMZSQL-01, EGTN-WDS-WEB1.

It must be possible to deny a particular login access to the server if necessary

ATTACK VECTORS (EASY Exploitability): Any exposed API call can act like as an attack vector.

For vulnerability MS-091, if all versions of the .NET libraries must be patched to completely remedy the issue, the developer obtained the older .NET versions that will be applied to the servers as needed. Patches for versions 3.5 and 4.0 were already applied.

In this report I will be describing the ways in which networks can be attacked, also be giving real life example of each of the below.

Initially the Linux (Ubuntu) is run on an virtual machine using VMWARE. The attack performed is on the IP address of the Linux OS.

By having the right filters and anti-spoofing (It stops the packets coming from non-IP broadcasts) will prevent these attacks. Controlling and monitoring the filter configurations, updating the filters and configuring the anti-virus software’s will help.

Even though this attack is very effective, it has its own weakness of the users becoming suspicious of unsolicited requests.
