The Chat Bubble WordPress plugin prior to version 2.3 is vulnerable to a Stored Cross-Site Scripting (XSS) attack due to insufficient sanitization and escaping of specific contact parameters. This vulnerability (CVE-2022-3415) can be exploited by unauthenticated attackers, who can inject malicious scripts via contact parameters. These scripts may then execute when an administrator views the related contact message, potentially leading to compromise of the WordPress application or stealing of sensitive information.
Exploit Details
The Chat Bubble plugin does not adequately sanitize and escape certain contact parameters before storing them in the chat message. This allows an attacker to inject malicious JavaScript payloads, which will execute when an administrator views the chat message.
An attacker can start a chat session and input a malicious payload like the following
Hello, my name is <script>/*malicious code here*/</script>
This payload will be stored in the chat message without proper escaping and sanitization. When the administrator views the chat message, the malicious code will execute, potentially leading to unauthorized access to the application or sensitive data.
The plugin normally would sanitize the user input, but it fails to account for some specific parameters in the chat payload. This oversight allows the attacker to exploit the vulnerability and inject the malicious XSS payloads in the contact parameters.
