DESCRIPTION:
High-Tech Bridge SA has discovered multiple vulnerabilities in
Dotclear, which can be exploited by malicious people to conduct
cross-site scripting attacks.

1) Input passed to the "login_data" POST parameter in admin/auth.php
(when "new_pwd" and "new_pwd_c" are set) 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 "nb" parameter in admin/blogs.php, "type",
"sortby", "order", and "status" parameters in admin/comments.php, and
"page" parameter in admin/plugin.php (when "p" is set to "tags", "m"
is set to "tag_posts", and "tag" is set to a valid tag name) 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.

The vulnerabilities are confirmed in version 2.4.1.2. Prior versions
may also be affected.

SOLUTION:
Update to version 2.4.2.
