Geeklog HTML Injection Vulnerabilities

Geeklog is prone to multiple HTML Injection vulnerabilities due to a lack of sufficient sanitization performed on data that is parsed from forum interface form fields. An attacker with sufficient privileges to create a forum post may use the forum form fields as a conduit to inject malicious HTML and script code into dynamic Geeklog content. The malicious HTML may be rendered in the browser of an unsuspecting user who views the malicious post, leading to code execution in the context of the affected site.

Mitigation:

Ensure that user-supplied input is properly sanitized before being parsed and rendered.
