Description:
Some vulnerabilities have been reported in Invision Power Board, which can be exploited by malicious users to conduct script insertion attacks or bypass certain access restrictions.
1) Input passed to unspecified fields in the user profile is not properly sanitised in ips_kernel/class_ajax.php before being used. This can be exploited to insert arbitrary HTML and script code, which is executed in an administrative user's browser session in context of an affected site when the malicious user's profile is being viewed.
Successful exploitation requires that Invision Power Board is configured to use character sets different from "iso-8859-1" and "utf-8".
2) An error exists in the subscription manager when processing payments. This can be exploited to modify a member's ID via a specially crafted payment form.
Successful exploitation allows e.g. demoting administrators and moderators to the subscriber's group, but requires that the subscription packages are enabled.
The vulnerabilities are reported in versions 2.3.1. Prior versions may also be affected.
Solution:
Download version 2.3.1, which has been updated to fix the vulnerabilities.
