Web applications have become the Achilles heel of IT security. Web application vulnerabilities are now the most prevalent at more than 55 per cent of all server vulnerability disclosures.
This figure doesn't include vulnerabilities in custom-developed web applications, so it may be just the tip of the iceberg. This

from gaining control over the application and obtaining easy access to the server, database, and other back-end IT resources.
