Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

DESCRIPTION:
Some vulnerabilities have been discovered in Sphider, which can be
exploited by malicious people to conduct cross-site scripting attacks
and SQL injection attacks.

1) Input passed to the "category" parameter in search.php is not
properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.
This can also be exploited to execute arbitrary HTML and script code
in a user's browser session in context of an affected site via SQL
error messages.

2) Input passed to the "catid" parameter in
templates/standard/search_form.html and
templates/dark/search_form.html 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 have been confirmed in version 1.3b. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
1) Soot
2) Reported by an anonymous person.
