What Are the Most Common Types of Vulnerabilities a Scanner Can Detect?

The most common types of vulnerabilities that a scanner can detect include:

• SQL Injection: This vulnerability occurs when an attacker manipulates a web application’s database query by injecting malicious SQL code. Scanners can identify places where user inputs are not properly sanitized, making it easier for attackers to access sensitive data or execute unauthorized commands.
• Cross-Site Scripting (XSS): XSS vulnerabilities allow attackers to inject malicious scripts into web pages viewed by users. Scanners detect these vulnerabilities by analyzing how input fields interact with the output and identifying points where user-provided data is not adequately escaped, potentially compromising user sessions or data integrity.
• Cross-Site Request Forgery (CSRF): CSRF vulnerabilities can trick a user into executing unwanted actions on a web application where they are authenticated. Scanners look for the absence of anti-CSRF tokens in forms and requests, which can help prevent unauthorized actions by ensuring that requests originate from legitimate users.
• Remote Code Execution (RCE): RCE vulnerabilities allow attackers to execute arbitrary code on a server, often leading to complete system compromise. Scanners identify potential RCE points by assessing how user inputs are handled and whether the application correctly enforces permissions and input validation.
• Insecure Direct Object References (IDOR): This vulnerability allows an attacker to access resources that they are not authorized to view or manipulate by modifying a URL or request parameter. Scanners can detect IDOR by checking for instances where user input directly influences resource access without proper authorization checks.
• Security Misconfigurations: These vulnerabilities arise from improper security settings in applications, servers, or databases. Scanners evaluate the configurations against security best practices to identify weaknesses, such as default credentials, unnecessary services running, or overly permissive access controls.
• Sensitive Data Exposure: This vulnerability involves the improper protection of sensitive information such as passwords, credit card numbers, or personal data. Scanners can identify areas where data is transmitted without encryption or stored insecurely, highlighting the need for strong encryption and secure storage policies.
• Broken Authentication: Broken authentication vulnerabilities allow attackers to compromise user accounts through weaknesses in the authentication process. Scanners assess login mechanisms for flaws like predictable login credentials, lack of account lockout mechanisms, and inadequate password policies to ensure robust authentication measures are in place.
• Outdated Software: Using outdated or unpatched software can expose applications to known vulnerabilities. Scanners can detect versions of software and libraries that are outdated, prompting updates to mitigate risks associated with known exploits.
