Invision Power Board Multiple Cross-Site Scripting Vulnerabilities

Invision Power Board is prone to multiple cross-site scripting vulnerabilities.

These issues are due to insufficient sanitization of input supplied via the 'c', 'f', , 'showuser', and 'username' URI parameters. This input will be included in dynamically generated pages, making it possible for an attacker to create a malicious link to a vulnerable site that includes hostile HTML and script code. This code may be rendered in the browser of a victim user who visits the malicious link, potentially allowing for theft of cookie-based credentials or other attacks.

These issues are reported to affect Invision Power Board 1.3 Final. Earlier versions may also be affected.
