The document outlines seven vulnerabilities in web applications that can lead to security threats, including the use of default values, cross-site scripting, SQL injection, brute force attacks, and access control loopholes. It emphasizes the importance of vulnerability assessment and penetration testing to protect web applications, highlighting that many are developed without adequate security considerations. The authentication module is particularly targeted by cyber attackers, especially in multi-level authentication systems.

1. 7 VULNERABILITIES
IN YOUR WEB
APPLICATION THAT CAN
OPEN THE DOOR TO
SECURITY THREATS

2. 01• Web applications come with a set of default
values and scripts which are used for testing
purposes and have not been properly removed
during the final Q&A processes.
• A typical cyber-attack uses these default values
to either gain access to the system or to assist in
launching an attack against the system.
DEFAULT VALUES

3. 02• Cross-Site Scripting is a way of writing content
into an HTML document by manipulation of
input variables.
• When a cyber actor manipulates a web
application content and adds additional
content, the actor can trick the web application
user that the content is real.
CROSS-SITE SCRIPTING

4. 03
• As the web applications use user-input variables
and use them to query the database, and
developers sometimes do not sanitize the user’s
input adequately, it leaves the possibility for
SQL injection attacks.
SQL INJECTION ISSUES AND
DATABASE AUDITING

5. 04• A brute force attack on a web application can
attempt to gain access to certain items using
enumeration.
• It is not only limited to usernames and
passwords. But can also be used to enumerate
files on the web application.
BRUTE FORCE

6. 05
• Brute force can also lead to a Denial-of-Service,
not only in terms of performance but also in
terms of accessibility of the web application.
• The application layer needs a strategic approach
to limit traffic based on rules.
DISTRIBUTED
DENIAL-OF-SERVICE

7. 06• Cyber actors take advantage of loopholes in the
access control.
• With session ID, once authorized, no further
permission is required to access the web
application.
ACCESS CONTROL

8. 07• Among the core components of web
applications, the authentication module is the
most targeted system by cyber attackers.
• Authentication De-synchronization is the
security issue arises in the multi-level
authentication systems where the attackers have
the knowledge of at least one of the
authentication credentials of the user.
AUTHENTICATION
DE-SYNCHRONIZATION

9. MANY WEB APPLICATIONS
ARE DESIGNED FROM THE
GROUND UP WITHOUT
TAKING SECURITY
CONSIDERATIONS INTO
ACCOUNT.

10. PEOPLE WHO DESIGN THE
WEB APPLICATIONS ARE
OFTEN PROJECT MANAGERS,
DEVELOPERS AND
SOFTWARE ENGINEERS WHO
MAY NOT POSSESS THE
KNOWLEDGE TO COVER THE
SECURITY ASPECTS.

11. VULNERABILITY
ASSESSMENT AND
PENETRATION TESTING IS
THE TOP PRIORITY FOR
ORGANIZATIONS TO KEEP
THEIR WEB APPLICATIONS
AWAY FROM CYBER
THREATS.
