New exploit to Oracle CVE-2007-4517 vulnerability
+0 Vote Up -0Vote Down

Summary

As part of GreenSQL’s Database security research,  we’ve been validating and extending coverage of known and unknown vulnerabilities in order to increase GreenSQL product security, at this post we will reveal a full working Prove of Concept for the CVE-2007-4517 vulnerability which executes arbitrary code.

The Exploit: PL/SQL/2007-4517 exploit is a PL/SQL procedure that exploits the CVE-2007-4517 vulnerability, also known as Oracle Database XDB.XDB_PITRIG_PKG.PITRIG_DROPMETADATA Procedure Multiple Argument Remote Overflow.

The vulnerability is caused due to a boundary error in the XDB.XDB_PITRIG_PKG.PITRIG_DROPMETADATA procedure when processing the OWNER and NAME arguments to create an SQL query.

This can be exploited to cause a buffer overflow by passing overly long OWNER and NAME arguments to the affected

Shortest SQL Injection Attack syntax

 

Overview
=======
In many cases, the user’s input is limited to a specific length.
Although the user’s input length is limited, many times the server is vulnerable to SQL Injection attack’s.
In this post, we’ll discuss two scenarios and how SQL injections attacks are being exploited using shortest SQL injection attack syntax.

Get Database Name through 2-fields attack
==============================
In this scenario, the attacker attacks a web application which receives First-Name and Last-Name, and outputs its matched e-mail address. (see appendix A)

The original SQL query sent to the database is:

select EmailAddress from Person.Contact where FirstName = ‘@fn’ and LastName = ‘@ln’; –where @fn and @ln are the user’s

Time-Based Blind SQL Injection

 
Overview
=======
Blind SQL Injection is an attack which the attacker gets an indication for the query execution success. The attacker doesn’t get the query results.
Most of the time, the indication bases on server errors or customized application errors.

Time-Based Blind SQL Injection
======================
Sometimes the attacker might not be able to identify the query execution success, because the server/application doesn’t show any error.
One of the techniques to get an indication for the query execution success called Time-Based Blind SQL Injection.
With this technique, the attacker executes functions that take some time to finish (for example: Benchmark, Delay, etc.). By measuring the time took the application to response, the attacker might be able to identify if the query

From the Security threat report 2011 by Sophos, Page 46:

“Cybercrime is encroaching more and more into the business space. Industrial espionage, spearphishing of important employees to breach network boundaries and mass theft of customer information are more diffcult to detect and have very serious consequences. At the same time, network boundaries are becoming ever more indistinct and porous as new technologies enable greater access from remote workers and mobile devices. In addition, legal requirements place greater emphasis on traceability and compliance with predefned standards of data hygiene.

Increasing amounts of sensitive data is stored, accessed and manipulated in databases connected to company websites as businesses increasingly interact with their customers

Database security, Database Firewall? Why should I use GreenSQL ?
+0 Vote Up -0Vote Down

Since the early days of GreenSQL, many people have written us asking why exactly they should implement a database security solution if they have already hardened their web application and are using a web application firewall, like mod_security, or even a professional closed source web application firewall such as Imperva, Breach, or F5.

The answer is not as simple as you may think, and I’m not going to preach to you about the great advantages using GreenSQL in front of your MySQL or PostgreSQL Database.

I’m going to highlight a few obvious current situations which will help you see the full picture of your Database security needs.

What is the core of the company?

When you come right down to it, the Database, eventually, is the core of your company or organization. All the information that the company is built
