Most Common Web Security Vulnerabilities
Common Web Security Vulnerabilities
One of the most common web security vulnerabilities is the lack of a secure login system. This vulnerability makes it easy for an attacker to read sensitive data from a database, and in some cases, even modify it. This can cause a number of problems, including XSS attacks. One solution to this problem is to implement input filtering. Input filtering enables you to specify which connections to use to run queries and validate user-provided parameters. This can also prevent HTML injection flaws.
Another common web security vulnerabilities is a weak security firewall. This weakness can allow hackers to bypass passwords and session keys. This can allow an attacker to access user accounts without the user realizing they have done it. Two-factor authentication can help prevent this vulnerability. However, it is inconvenient for users.
Misconfigured web applications are also prone to vulnerabilities. Incorrectly configured web servers can provide crackers with critical information such as error handling information. It is also important to ensure that sensitive data is encrypted at all times. For example, credit card information should never be stored in an unencrypted form. Additionally, user passwords should be hashed for maximum security. Furthermore, the encryption algorithms should be strong enough to deter attackers. The best algorithms to use for encryption include AES and RSA, which are recommended by most web security standards.

Another common web security vulnerability is the injection vulnerability. This happens when a malicious piece of code or command modifiers is passed through a web page. This can happen through a number of attack vectors, including system calls, shell commands, and back-end databases. Cyber attackers can take advantage of this vulnerability to gain unauthorized access to sensitive data and steal confidential information from users.
Input validation is another important step in ensuring your website is secure. The goal of input validation is to ensure that the data you input is properly formatted. Otherwise, it can cause your site to malfunction. The lack of input validation is another common web security vulnerability, and the failure to perform input validation can allow an adversary to perform various injection attacks such as buffer overflow, canonicalization, and many more.
A session hijacking attack is a serious problem that can compromise an application. A session identifier (SID) is often unencrypted and can be reused by an attacker. The attacker can then use this session identifier to access other objects. By hijacking a session, he can then gain unauthorized access to the application.
Another common vulnerability is the SQL injection vulnerability. This occurs when an attacker inserts malicious code into a web server, releasing the infected data to all users. This attack can lead to loss of data and other safety risks.
