JoomlaWorks K2 Multiple Field Input HTML Injection Vulnerabilities

K2 for Joomla! is prone to multiple HTML-injection vulnerabilities because the application fails to properly sanitize user-supplied input before using it in dynamically generated content.

Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected site, 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.

Versions prior to JoomlaWorks K2 2.4 are vulnerable; other versions may be affected.
