Wiki Web Help is prone to a cross-site scripting vulnerability and multiple HTML-injection vulnerabilities because it fails to properly sanitize user-supplied input before using it in dynamically generated content.
Attacker-supplied HTML and script code could run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
Wiki Web Help 0.2.7 is vulnerable; other versions may also be affected.
The following example URI and input are available:
<div onmouseover="alert(0)" style="margin:-500px;width:9999px;height:9999px;position:absolute;"></div>
