May 4, 2022 Providing insight into web application attack surfaces, real world attacker experience, vulnerability prioritization and remediation guidance. This post highlights how cross-site scripting has adapted to todays modern web applications, specifically the API and Javascript Object Notation (JSON).
Aug 22, 2019 Heres what you need to know to protect them from XSS attacks. What is cross-site scripting (XSS), and why is the problem getting worse? An XSS attack involves an attacker injecting malicious scripts into a web page or application. When the victim visits the page or application, the code is executed.

Jan 30, 2024 Data Theft: Attackers can use XSS to steal sensitive information such as login credentials, credit card details, or personal data from unsuspecting users. Identity Theft: By exploiting XSS, attackers can impersonate users, potentially leading to identity theft and unauthorized access to accounts.
3 Answers. Sorted by: 5. Encode unsafe characters in the response (how do I do this? using \uxxxx?) Yes. < to \u003C in particular. There may be an option in your JSON encoder to do this already (eg in PHP, JSON_HEX_TAG ); otherwise, it's a simple job to do a string replace after the encoding.
Aug 10, 2023 This post highlights how cross-site scripts has adapted to todays modern-day web applications, concrete and API and Javascript Object Stylistic (JSON).
Jan 31, 2024 XSS poses persistent threats to web apps, risking data breaches and user trust. Understanding XSS types and testing methods is crucial for effective mitigation. Prevention techniques such as input validation, output encoding, and CSP implementation improve app security.
Jan 28, 2021 From what I understand, since the Content-Type is set to application/json, the API as such is safe from XSS. The client needs to ensure that the output is encoded to prevent any XSS attacks. To add an additional layer of security, I can add some input encoding/validation in the API layer.
XSS - selects XSS modules. SQL Injection and XSS - selects SQL Injection and XSS modules Users are able to save and load the custom/user attack policies. In the following example, we have selected All Modules as we would like to test Hackazon application against all the threats. Click on the Next button.
May 4, 2022 XSS is a type of injection attack, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to execute malicious code generally in the form of a browser-side script like JavaScript, for example against an unsuspecting end user.
Below is my function for escaping potential XSS attacks: function escapeScriptTags($value) { return json_encode(htmlentities($value), JSON_HEX_QUOT|JSON_HEX_TAG|JSON_HEX_AMP|JSON_HEX_APOS); } The issue I'm having is that the returned string has double quotes concatenated and appended to it.
Jun 27, 2022 Nearly every modern application utilizes or is an API. Today, its almost impossible to do anything online without interacting with an API. Thats why cyberattacks are increasingly targeting APIs, and theyve become a large part of the application attack surface.

JSON.stringify () is perhaps one of the most mundane APIs in modern browsers. The functionality to translate a JavaScript object into a string-based representation is hardly thrilling. But when the stars align, a simple JSON serialization operation can result in a significant XSS vulnerability.
What is it? An XSS attack occurs when a malicious actor injects client-side scripts and/or HTML into a web page for execution by the web browser of another user. There are three common types of XSS attacks: reflected, persistent, and DOM based.
Apr 17, 2012 The server does not perform any side effects or other actions, when you request the JSON data. (This means you don't need to worry about CSRF attacks.) There is no confidential data anywhere in this JSON data structure. (Not relevant for XSS, but relevant to JSON data theft, as @Rook explains.)

Jun 20, 2013 Last updated at Sat, 20 Jan 2024 15:11:45 GMT. A common misunderstanding in the world of Web Application Security is the difference between the consequences of a cross-site scripting vulnerability and the consequences of an SQL Injection Attacks (SQLi). We can even go a step back and say the misunderstanding is on a much broader level; the ...

Traditional web application firewalls (WAFs) stand between your web applications and the internet, helping to protect against various types of attacks such as SQL injection and cross-site scripting (XSS) by filtering suspicious web requests.
