Understanding Web Application Attacks

Web application threats are constantly on the rise. The sophistication and speed of web application cyberattacks can cause significant damage to businesses. In most cases, they result in further security breaches, which may have financial and legal consequences.

The most common reasons for web application attacks are incorrectly configured web servers, bad application architecture, and failure to check or sanitize form inputs. It is important to have a basic understanding of how these attacks work.

Here is a list of the most significant web application security issues:

Unwanted exposure of sensitive data

Sensitive information can be easily hacked if security measures like encryption at rest or in transit are not used during communication with the browser. Criminals can steal or manipulate information and commit cybercrimes like credit card fraud, identity theft, etc.

CSS or XSS (Cross Site Scripting)

CSS or XSS (Cross Site Scripting) security flaws aid attackers in running scripts in a user’s browser to damage websites, hijack user sessions or redirect users to other domains.

Software and integrity failures due to insecure deserialization

Deserialization issues frequently lead to remote code execution and provide hackers the ability to carry out a wide range of attacks.

XML external entities misconfiguration

Insecure XML processors expose users to the risk of unauthorized access to sensitive data, modification of existing data, and execution of malicious code. This vulnerability also allows Remote Code Execution, Denial of Service, and Server Side Request Forgery by cyber criminals.

Parameters and URL injections

An injection vulnerability, such as a SQL, OS or LDAP injection vulnerability, arises when an interpreter receives a command or query containing suspicious input. An attacker’s hostile data could lead the interpreter to access data without authorization or execute undesired commands. This could lead to the deletion of tables, unauthorized viewing of lists, and unauthorized access to the administration system.

Broken or insecure authentication

This occurs when application functionalities responsible for session management and authentication are incorrectly implemented. It lets attackers take over the identities of other users temporarily or permanently. It’s also easy for them to steal session tokens, passwords, or keys.

Use of software libraries and packages with security loopholes

A server takeover and significant data loss can result from an assault on weak software components. For example, an application may be using a weak or compromised version of the software framework or the libraries in application development, which may be exploited by attackers.

Inadequate security logging and monitoring

Inadequate recording, monitoring, and integration of event response can aid attackers in launching more attacks on systems. This allows attackers to further escalate their attacks.

Flawed access control restrictions

Access control lets you control which parts of a website and which application data different visitors can visit. If these restrictions are not correctly imposed, attackers can easily exploit these vulnerabilities to access restricted data.

Misconfigured security settings and features

It provides an easy entry point for attackers into the website and is one of the most severe web application security vulnerabilities. Attackers can use inadequate or ad hoc configurations, exposed cloud storage, verbose error messages containing sensitive data, and improper HTTP headers.

Organizations should follow secure coding standards to create robust and secure web applications. To create secure website applications contact Centex Technologies at Killeen (254) 213 – 4740, Dallas (972) 375 – 9654, Atlanta (404) 994 – 5074, and Austin (512) 956 – 5454.

What Are Web App Attacks?

April 29, 2015

Web app attacks are among the most common types of data breaches posing serious threat to a business’ cyber security. These attacks can jeopardize the functioning of your website, inhibit its performance and in most cases, crash the website completely. As most web applications run in the browser, any potential security flaw can permit hackers to exploit the vulnerabilities in the apps and damage the business website.

Common Web App Attacks:

  • Cross-Site Scripting (XSS): These attacks use a vulnerable web application to send malicious client side code to be executed by the end user. Once this is done, the hacker can have access to browser’s session tokens, cookies and other sensitive data.
  • SQL Injections: This type of attack manipulates the vulnerabilities in the web apps in order to gain access to the databases and other information that they hold. These may include things such as email addresses, names, telephone numbers, postal addresses, bank account information, credit card details etc.
  • Cookie Poisoning/Hijacking: A number of web applications use cookies to save and retrieve user information like login id, password and email address. Cookie poisoning allows the hacker to access unauthorized information about the user to create new accounts or penetrate the existing account.
  • Directory Traversal: It is a form of HTTP attack in which the cybercriminal installs malicious software on the web server. If the attempt is successful, the hacker can have access to the restricted directories and execute commands that are outside of the server’s root directory.
  • Remote Command Execution: This allows the hacker to execute remote and random commands on the host computer through a vulnerable web application. These attacks are largely possible due to insufficient input validation.

Counter Measures Against Web App Attacks

  • Set Safe Permissions: Most often, the web apps are attacked due to the preventable vulnerabilities present in them. Make sure you set safe permissions for your files so that they can be written or executed only by the web server.
  • Scan For Vulnerabilities: This is extremely important to identify the potential vulnerabilities in your application that may make it open to cyber-attacks.
  • Use Application Firewall: Installing and regularly updating firewall can also provide an added layer of defense against web app attacks.
  • Restrict Unauthorized Users: Make sure that the write access to your files should be given to a limited number of users. This is applicable both for the server side and web app backend.

We, at Centex Technologies can help you evaluate and implement web app security measures in your organization. For more information, you can call us at (855) 375 – 9654.
