Pearl Forums SQL Injection and Local File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA17533

VERIFY ADVISORY:
http://secunia.com/advisories/17533/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
Pearl Forums 2.x
http://secunia.com/product/6117/

DESCRIPTION:
Abducter has discovered some vulnerabilities in Pearl Forums, which
can be exploited by malicious people to conduct SQL injection attacks
and disclose sensitive information.

1) Input passed to the "forumsId" and "topicId" parameters in
"index.php" isn't properly sanitised before being used in a SQL
query. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

2) Input passed to the "mode" parameter in "index.php" isn't properly
verified, before it is used to include files. This can be exploited to
include arbitrary files from local resources.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities have been confirmed in version 2.4 and has also
been reported in version 2.0. Other versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
