A potential Cross-Site Scripting (XSS) vulnerability has been identified in the /wireui/button endpoint, specifically through the label query parameter. Malicious actors could exploit this vulnerability by injecting JavaScript into the label parameter, leading to the execution of arbitrary code in the victim's browser.
The /wireui/button endpoint dynamically renders button labels based on user-provided input via the label query parameter. Due to insufficient sanitization or escaping of this input, an attacker can inject malicious JavaScript. The following URL demonstrates the vulnerability:
https://wireui.dev/wireui/button?label=Cancel&1%25%7ds8dk0%3E%3Cscript%3Ealert(1)%3C/script%3Ez1qt3=1
By crafting such a request, an attacker can inject arbitrary code that will be executed by the browser when the endpoint is accessed.
To demonstrate the vulnerability, visit the following URL:
/wireui/button?label=<script>alert(1)</script>
Upon loading the page, the injected JavaScript will execute, displaying an alert with the message "1." This confirms the vulnerability and highlights that user input is not being properly escaped or sanitized.
If exploited, this vulnerability could allow an attacker to execute arbitrary JavaScript code in the context of the affected website. This could lead to:
The severity of this vulnerability depends on the context of where the affected component is used, but in all cases, it poses a significant risk to user security.
