DESCRIPTION:
A weakness and some vulnerabilities have been discovered in Elgg,
which can be exploited by malicious people to disclose sensitive
information and conduct cross-site scripting and SQL injection
attacks.

1) A SQL error can be exploited to disclose certain sensitive
information within a SQL error message.

2) Input passed to the "internalname" parameter in
engine/handlers/pagehandler.php (when "handler is set to "embed" and
"page" is set to "media") 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 this vulnerability requires that the Embed
plug-in is enabled.

3) Input passed to the "container_guid" and "owner_guid" parameters
in engine/handlers/pagehandler.php (when "handler" is set to
"search") is not properly sanitised before being used in a SQL query.
This can be exploited to manipulate SQL queries by injecting arbitrary
SQL code.

The weakness and the vulnerabilities are confirmed in version 1.7.10.
Prior versions may also be affected.

SOLUTION:
Update to version 1.7.11.

PROVIDED AND/OR DISCOVERED BY:
1, 2) The vendor credits Aung Khant, YGN Ethical Hacker Group.
3) Lostmon Lords.
