DESCRIPTION:
Two vulnerabilities have been reported in Invision Power Board, which
can be exploited by malicious users to bypass certain security
restrictions and by malicious people to conduct cross-site scripting
attacks.

1) Input passed via the URL when adding an avatar isn't properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

2) An unspecified error in the permission handling can be exploited
by moderators to moderate an arbitrary forum without proper
permissions.

The vulnerabilities have been reported in version 2.1.6 (before
2006-06-30) and prior for the 2.1 branch.
