Web protection has emerged as a major problem for modern businesses. In recent years, there has been a large rise in the number of cybercrimes. In 2017, the cost of cyberattacks was projected to be $1 billion, but by 2020, the cost had risen to $4 billion. Web apps are among the most common targets for hacker attacks because they have easier access to a wider audience, allowing malicious code to spread more quickly. This blog will look at the most popular web application development bugs and potential ways to avoid them.
Authentication is the method of verifying a user’s identity by associating incoming data with a series of credentials such as biometric data, passwords, etc. Broken authentication, on the other hand, means that the session ID or user credentials are stolen.
Inadequate user credential security, poor password and username, forwarding the session ID as a URL, and other factors may lead to failed authentication.
- Multi-factor authentication (MFA).
- Rejection of insecure passwords.
- The duration of the session.
- Security warnings.
When untrusted or unfiltered data enters a server or browser as part of a query, this is referred to as injection. SQL, NoSQL, LDAP, OS, and other types of injections are all possible. SQL queries, on the other hand, are the most frequent object of malicious intent. Attackers gain access to critical server data by submitting unfiltered data via the SQL questionnaire. As a result, they will execute administrative tasks, access user private information, credit cards, and passwords, among other things.
- Validation of inputs
- Prepared statements with parameterized queries;
- Restricted consumer privileges.
Inadequate Access Control
Inadequate/Broken access control is a type of website application development failure in which users can perform actions they may not perform. Developers with malicious intent will use it to bind to other user accounts, alter information inside them, access confidential data, and, in the worst-case situation, gain complete control of the programme. Poor functional monitoring and a lack of automatic identification are the most common causes of access control vulnerabilities.
- Improved access protection as a preventative measure.
- By contrast, deny access to functionality.
Exposed Sensitive Data
This web application protection problem involves disclosing confidential consumer details such as phone numbers, account information, credit card numbers, and so on. Data leakage vulnerability can serve as a wake-up call for businesses because it can lead to more severe effects such as compromised security, injection, man-in-the-middle, or other forms of attacks.
- Improved data security;
- Security protocols
External Entities in XML (XXE)
XXE attacks target web applications that handle XML input. Outdated or improperly installed XML processors normally cause them. Using this loophole, hackers can access the back-end and external networks and perform server-side request forgery (SSRF).
- It can be prevented by disabling DTD.
Misconfiguration of Security
One of the most common problems with web applications is security misconfiguration. It is a concern created by a lack of access monitoring application or by security errors. The bulk of programmes are vulnerable due to missing specifications, default configurations that have remained unchanged for an extended period of time, unencrypted files, unnecessary running services, and so on. Misconfiguration of security will result in serious data breaches that damage a company’s credibility and cause substantial financial losses.
- Consistent vulnerability scanning and updates.
Making Use of Components With Known Vulnerabilities
The sophistication of web development contributes to the difficulties of detecting vulnerabilities. Modern web app architecture is heavily reliant on different frameworks, libraries, APIs, and so on, including other components that can be a priority for a hacker attack and the app itself.
- Eliminating superfluous elements.
- Accept only trusted code; and
- Perform ongoing security checking.
Deserialization that is not stable
When it comes to vulnerable deserialization, untrusted data does harm to the mobile server by remotely running malicious code, bypassing security, and changing app logic.
- Deserialization with restricted entry.
Inadequate logging and monitoring
Inadequate logging and surveillance enable attackers to remain undetected when attempting to accomplish their dangerous objectives. This weakness is the most popular cause why businesses are unable to fix data breaches. Furthermore, inadequate recording and tracking could result in additional device penetrations and massive losses.
Cross-Site Scripting (XSS)
The XSS flaw allows hackers to execute malicious scripts in the user’s browser. They can be carried out by clicking on the inserted connection. If the user clicks on it, the intruder gains access to critical functions (webcam, location, etc.), hijacks the session, redirects the user to unsafe websites, and so on.
Security is a critical component of modern web app growth. To remain competitive in the industry, businesses must develop new security technologies to combat hackers while still providing their customers with stable and secure software.
However, much of web application development security depends on the developers’ knowledge of cyber attacks and the application’s operations being monitored regularly. As a result, ensuring that your tech developers are well-versed in the most popular web application security flaws would assist you in protecting your web app and building a stronger company profile.
