Web application securities are widely used by e-commerce websites. While they offer a wide variety of benefits ranging from streamlining processes to digitalizing services, the web application has become the target for the exploitation of vulnerabilities. These vulnerabilities might involve a system flaw or weakness in a web-based application. They have been around for years due to not validating or sanitizing form inputs, misconfigured web servers, and application design flaws. These vulnerabilities are not the same as other common types of vulnerabilities because web applications need to interact with multiple users across multiple networks, and that level of accessibility is easily taken advantage of by hackers. Here are some of the most common ones:
1. Application Vulnerabilities – Software system flaws is an application that could be exploited to compromise the security of the application. Once a hacker has found a flaw or application vulnerability, he/she can target the confidentiality, integrity, or availability of resources possessed by an application.
While there are hundreds of tools and techniques for exploiting application vulnerabilities, there are a few which are more common than others. These include Cross Site Scripting, SQL Injection, LDAP Injection, Cross Site Request Forgery, Insecure Cryptographic Storage, and Application Vulnerability Management.
3. Credentials Management - This kind of attack attempts to breach username and password pairs with the sheer intention to take control of user accounts. Once a system is accessed, an attacker can steal, manipulate, or delete important data. It allows them to install additional malware and gain broader access to system and files. There are four primary ways attackers breach credentials- the use of a hard-cooked password and use of insufficiently protected credentials being the most common ones.
4. CRLF Injection - CRLF injections are software application coding vulnerability that mostly occurs when an attacker injects a CRLF character sequence when it was not expected. These vulnerabilities also result from data input that is not neutralized, incorrectly neutralized. Under these attacks, hackers provide specially crafted text streams with CRLF injections that result in unexpected actions by web applications. CRLF injection can exploit security vulnerabilities at the application layer. For example, by exploiting the CRLF injection flaw in an HTTP response, attackers can modify application data and compromising integrity.
5. Directory Traversal - Directory traversal is an HTTP exploit that is used by attackers to gain unauthorized access to restricted directories and files. These kinds of vulnerabilities are the result of insufficient validation of browser input from users. And, they can be located in web server software/files or in application code that is executed on the server. They can exist in a variety of programming languages, such as Python, PHP, Apache, ColdFusion, Perl and more. Companies generally rely on manual penetration testing techniques to detect directory traversal vulnerabilities. And, hackers are able to exploit vulnerabilities in application code by sending URLs to the web server that instruct the server to return specific files to the application.
