A web application firewall (WAF) is a specific form of application firewall that filters, monitors, and blocks HTTP traffic to and from a web service.By inspecting HTTP traffic, it can prevent attacks exploiting a web application's known vulnerabilities, such as SQL injection, cross-site scripting (XSS), file inclusion, and improper system configuration.

A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
The technique transforms an application SQL statement from an innocent SQL call to a malicious call that can cause unauthorized access, deletion of data, or theft of information. [ 3 ] One way that DAM can prevent SQL injection is by monitoring the application activity, generating a baseline of “normal behavior”, and identifying an attack ...
An example of how you can see code injection first-hand is to use your browser's developer tools. Code injection vulnerabilities are recorded by the National Institute of Standards and Technology (NIST) in the National Vulnerability Database as CWE-94. Code injection peaked in 2008 at 5.66% as a percentage of all recorded vulnerabilities. [4]
SQL injection; Vulnerabilities in applications and services (e.g. web server software such as NGINX or content management system applications such as WordPress); [7] [8] File processing and uploading vulnerabilities, which can be mitigated by e.g. limiting the file types that can be uploaded; [8]
XSS can be persistent, when attackers save the malware in a data field and run it when the data is loaded; it can also be loaded using a malicious URL link (reflected XSS). [28] Attackers can also insert malicious code into the domain object model. [30] SQL injection and similar attacks manipulate database queries to gain unauthorized access to ...

SQL Injections. SQL injection is a code injection technique used by threat actors to attack any data-driven applications. Threat actors can inject malicious SQL statements. This allows threat actors to extract, alter, or delete victim's information. [20] Denial of Service Attacks
