Can you explain this vulnerability to me?
CVE-2025-45960 is a Stored Cross-Site Scripting (XSS) vulnerability in the tawk.to Live Chat web application version 1.6.1. It occurs because the application stores and displays user-supplied input without proper validation or encoding. This allows an attacker to inject malicious JavaScript code into the chat input, which is then stored on the server and executed in the browsers of users who view the malicious content, potentially leading to unauthorized actions within the user's browser. [1]
How can this vulnerability impact me? :
This vulnerability can lead to theft of sensitive information, phishing attacks, and damage to the application's brand reputation. When malicious scripts execute in a user's browser, attackers can steal cookies, session tokens, or other sensitive data, trick users into revealing confidential information, or perform actions on behalf of the user without their consent. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the tawk.to Live Chat input fields for stored Cross-Site Scripting (XSS). One approach is to inject a test payload such as an HTML image tag with an onclick event containing JavaScript, for example: `<img src='x' onclick='alert(document.domain)'>`. If the script executes when the stored input is rendered in the browser, the vulnerability is present. Detection involves interacting with the chat input and observing if the injected script runs. There are no specific network commands provided, but manual or automated web application security testing tools that support stored XSS detection can be used. [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include applying proper input validation and output encoding on all user-supplied inputs in the tawk.to Live Chat application to prevent malicious scripts from being stored and executed. If a patch or updated version of the software is available that addresses this vulnerability, it should be applied promptly. Additionally, restricting or sanitizing HTML input in the chat fields can reduce risk. Until a fix is applied, consider disabling or limiting the live chat feature to reduce exposure. [1]
