Discussion
Curverider Elgg Templates HTML Injection Vulnerability
Elgg is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input before using it in dynamically generated content.
Exploits require the attacker be an authenticated user; this permission may be trivial to acquire.
Successful exploits will allow attacker-supplied HTML and script code to 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.
Elgg 1.0 is vulnerable; other versions may also be affected.
