Web Applications in Danger

What are Web What are Web Applications?Applications?

• Login forms, search forms, blogs and forums, shopping carts, newsletter submit fields

• Easy, seamless and immediate retrieval and submission of data through a web browser.

• Updated and maintained without distributing and installing software on client computers.

• Immensely popular.• Web applications as business drivers.• AJAX applications – the next generation.

Web Application Web Application Security IssuesSecurity Issues

Web App Security ConcernsWeb App Security Concerns• Bring grave security risks:

– Available 24x7x365 – Publicly available for legitimate users

and hackers– Direct access to backend databases– Most web applications are custom-made – These custom applications are the most

susceptible to attack.– Lack of awareness equating web

security to network security.

Layers to SecurityLayers to Security

Nine MythsNine Myths: Eyes Wide : Eyes Wide Shut?Shut?

1. Network security scanners protect the application layer.

2. Application vulnerabilities = network and system vulnerabilities.

3. Firewalls protect the application layer.4. IPS/IDS defeat application attacks5. Network devices understand application context6. SSL secures the application. 7. Vulnerability scanners protect the web –

matching vulnerability signatures will do the trick.8. Annual or quarterly vulnerability assessment are

enough.9. Patch Management is immediate and satisfactory.

The Jeffrey Rubin StoryThe Jeffrey Rubin Story• Network Security is Not Enough

Syracuse University School of Information StudiesPresident of Internet Consulting Services “Review: Web Vulnerability Scanners”, SOAPipeline, September 2005.

• Network security is not enough as web applications require port 80 to be open to communicate with the database to deliver the function it was designed for

Eric S. RaymondEric S. Raymond• ESR is a well known figure in the

hacker community and maintains the “Hacker’s Dictionary”.

• A famous quote in response to “how long will it take me to learn to hack?”:

• “…if you are a real hacker, you will spend the rest of your life learning and perfecting your craft”.

Have you been hacked?Have you been hacked?• Have you been hacked?

– Are you certain?– If web applications are not secure….– …then your entire database of sensitive

information is at serious risk.

Why Organizations Need to Worry

Who’s Being Hacked?Who’s Being Hacked?• Choice Point Inc ($15m)• University of Southern California ($140k +)• Microsoft (Website defacement)• PayPal (Account information stolen; cost

unknown)• Victoria’s Secret ($50k fine)• Hotmail (XSS detected – not fixed)• Amazon (XSS detected – not fixed)• Petco (credit cards of 500k customers

stolen)

TJX Companies IncTJX Companies Inc• 40 million customer cards stolen

– USA, Hong Kong, Sweden, UK and Ireland.• Lawsuits to date account for about

US$ 5 to 10 million• Government of Canada launching an

investigation• Breach probably started in 2003 and

discovered in December 2006.

Web Security Hard Cold Web Security Hard Cold FactsFacts

• Gartner: – 75% of Website hacks happen at the web application level.

• Cisco:– 95% of web applications have serious flaws,

• 80% of which are vulnerable to Cross Site Scripting• Acunetix Research through Free Audits (published):

– 70% of sites scanned have medium to high risk vulnerabilities including:

• SQL Injection• XSS• Source Code Disclosure

• Our competition show similar statistics:– Jeremiah Grossman (Whitehat) states our figure is

conservative.

The Cost of being HackedThe Cost of being Hacked• Closure.• Lost Customer confidence, trust and

reputation. • Lost Brand equity.• Downtime.• Lost revenues and profits.• Ban on processing credit cards.• Repair the damage.• New security policies.• Legal implications including fines and

damages.

How do Hackers Work? (1)How do Hackers Work? (1)• First step towards deploying a web security

infrastructure.• Always steps ahead• Wide repertoire of hacking techniques they

will throw at custom web applications.• Very close knit community that keeps itself

abreast to propagate further hacking.– Check out sla.ckers.org and slashdot.

• Systematic plan of action that entails four steps.

How do Hackers Work? (2)How do Hackers Work? (2)• Step 1: Analyse the server infrastructure

• Step 2: Survey the Website

• Step 3: Check for Input Validation Errors

• Step 4: Mount the Attack

• Static Methods – the ‘Known’:– Known exploits

– Directory Enumeration

– Web Server Exploits

• Dynamic Methods – the ‘Unknown’:– SQL Injection– Cross-site Scripting– Directory and Link Traversal– Source Code Disclosure– Common File Checks– Parameter Manipulation or

Passing– Hidden Web Paths– Extension and Backup

Checking– Path Truncation– Java Applet reverse

SQL InjectionSQL Injection• SQL is a database query language for

data storage, manipulation and retrieval.

• Standard for all web applications to interact with their databases be they Oracle, My SQL, MS Access…

• SELECT, DROP, INSERT, DELETE• SQL Injection is when a hacker is able

to inject SQL syntax in an input field to gain access to the database

SQL Injection DemoSQL Injection Demo• http://testasp.acunetix.com/• Example of a forum that requires

login for posting informationSELECT idFROM loginsWHERE username = ‘I-am-a-hacker'AND password = anything' or 'x'='x

• This is a simple example.

Types of Web Vulnerability Types of Web Vulnerability ScannersScanners

• Web Vulnerability Scanners– Signature Matching Approach (Standard

Web Vulnerability Scanners)– Heuristic Methodology Approach

(Intelligent Web Vulnerability Scanners)• Automated v. Manual Scans

– The importance of automation– Nothing beats the human touch

Signature MatchingSignature Matching• The majority of Vulnerability Scanners are

ineffective because they look for weaknesses based on signature matching.

• Similar to anti-virus software.• Almost perfect for all popular systems and

widely deployed applications:– Effective against Known (Static) Vulnerabilities– Ineffective against Unknown (Dynamic)

Vulnerabilities and for Custom Applications.

Heuristic Scanning Heuristic Scanning MethodologyMethodology

• Hacks are not based on signature-file.• Custom web applications are a honey pot.• Logic of the “heuristic methodology” is:

– Proactive v. Reactive– Acts like a hacker– Focuses on the arsenal of hacking methods

rather than the vulnerabilities themselves.• Web vulnerability scanning depends on:

– (a) how well your site is crawled, and – (b) on the ability to test the various hacking

methods and techniques against web applications.
