DESCRIPTION:
Aung Khant has discovered multiple vulnerabilities in Elgg, which can
be exploited by malicious people to conduct cross-site scripting
attacks.
1) Input passed to the "page_owner" parameter in mod/file/search.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 "content" parameter in
mod/riverdashboard/index.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) Input passed to the "internalname" parameter in
engine/handlers/pagehandler.php (when "handler" is set to "embed" and
"page" is set to "upload") 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.
4) Input passed to the "page" parameter in
engine/handlers/pagehandler.php (when handler is set to "pages") 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.
5) Input passed to the "send_to" parameter in
engine/handlers/pagehandler.php (when "handler" is set to "messages"
and "page" is set to "compose") 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.
6) Input passed to the "container_guid" parameter in
engine/handlers/pagehandler.php (when "handler" is set to "pages" and
"page" is set to "new") 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.
Successful exploitation of the vulnerabilities #5 and #6 may require
that the victim is running Internet Explorer or Konqueror.
The vulnerabilities are confirmed in version 1.7.9. Prior versions
may also be affected.
SOLUTION:
Update to version 1.7.10.
