DESCRIPTION:
mghack has discovered multiple vulnerabilities in e107, which can be
exploited by malicious users to conduct script insertion and SQL
injection attacks and by malicious people to conduct cross-site
scripting attacks.

1) Input passed via the URL to e107_images/thumb.php or rate.php is
not 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) Input passed to the "resend_name" POST parameter in
e107_admin/users.php is not 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.

3) Certain input passed to the "link" BBCode in user signatures is
not properly sanitised before being used. This can be exploited to
insert HTML and script code, which will be executed in a user's
browser session in context of an affected site if malicious data is
viewed.

4) Input passed to the "username" POST parameter in usersettings.php
is not properly sanitised before being used in a SQL query. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

Successful exploitation of this vulnerability requires that the
setting "Display name and login name may be different for" is set to
e.g. "everyone (public)" (not default) and that "magic_quotes_gpc" is
disabled.

The vulnerabilities are confirmed in version 0.7.26. Other versions
may also be affected.

SOLUTION:
Upgrade to version 1.0.0.
