Client Side Vulnerabilities / Local File Path Manipulation (DOM-Based)

Web and API


Local file path manipulation (DOM-based) is a type of client-side vulnerability in web applications and APIs that allows an attacker to inject malicious code into a vulnerable web application. This vulnerability is classified in the Common Weakness Enumeration (CWE) directory as CWE-79, and is also listed in the OWASP Testing Guide. This vulnerability is particularly dangerous because it allows an attacker to gain access to sensitive information within the web application, including passwords and authentication tokens.


The risk associated with this vulnerability is high, as it can allow an attacker to gain access to sensitive information within the web application. The attacker can also use this vulnerability to modify existing data, potentially leading to data tampering and data loss. Additionally, this vulnerability can lead to a complete compromise of the web application, as the attacker can gain access to the entire system.


In order to prevent this type of vulnerability, developers should use proper input validation techniques. This includes validating user input and sanitizing data before it is used within the web application. Additionally, developers should use secure coding practices when developing web applications, such as using secure coding libraries and limiting user privileges.
