Web application security threats are vulnerabilities or weaknesses in web applications that attackers can exploit to gain unauthorized access, steal data, or cause damage to the application or the organization.
Common web application security threats
- Injection attacks: This occurs when an attacker injects malicious code into a web application by exploiting vulnerabilities in the application. SQL injection and cross-site scripting (XSS) are some examples of injection attacks.
- Cross-site scripting (XSS): This type of attack occurs when an attacker injects malicious code into a web page that is then executed by a victim's browser. The attacker can use this to steal the victim's data, such as login credentials.
- Cross-site request forgery (CSRF): In this attack, the attacker tricks the victim into performing an action on the web application that they didn't intend to, such as making a payment or changing their password.
- Broken authentication and session management: If a web application has poor authentication and session management, it can allow attackers to gain unauthorized access to user accounts and steal sensitive information.
Examples of web application attacks
In 2017, Equifax suffered a data breach that exposed sensitive personal information, such as social security numbers and birth dates, of millions of its customers. The breach was caused by a vulnerability in the company's web application software.
In 2018, British Airways suffered a data breach that resulted in the theft of the personal and financial data of over 380,000 customers. The attackers were able to exploit a vulnerability in the company's web application payment system.
Potential impact of attacks on a business
- The potential impact of these attacks on a business can be severe and long-lasting. The consequences may include the following: Data breaches and other web application attacks can result in significant financial losses due to lost revenue, lawsuits, and fines.
- A successful web application attack can damage a company's reputation and erode customer trust, leading to loss of business and decreased revenue.
- Businesses that suffer data breaches may face legal liabilities if they fail to protect their customers' personal and financial information.
- Businesses that handle sensitive customer information are subject to regulatory requirements, and a data breach or other web application attack can result in non-compliance and penalties.
