TITLE:
Typo SQL Injection and Script Insertion Vulnerabilities

SECUNIA ADVISORY ID:
SA32272

VERIFY ADVISORY:
http://secunia.com/advisories/32272/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Typo 5.x
http://secunia.com/advisories/product/20290/

DESCRIPTION:
L4teral has discovered some vulnerabilities in Typo, which can be
exploited by malicious users to conduct SQL injection attacks, and by
malicious people to conduct script insertion attacks.

1) Input passed to the "comment[author]" and "comment[url]"
parameters when leaving a comment is not properly sanitised before
being stored. This can be exploited to insert arbitrary HTML and
script code, which is executed in a user's browser session in context
of an affected site when the malicious data is viewed.

2) Input passed to the "search[published_at]" parameter in
admin/pages is not properly sanitised before being used in SQL
queries. This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

Successful exploitation of this vulnerability requires valid blog
publisher credentials or higher.

NOTE: It was also reported that the same salt value is used to
generate all password hashes.

The vulnerabilities are confirmed in version 5.1.3. Other versions
may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
