TITLE:
Insanely Simple Blog Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA26105

VERIFY ADVISORY:
http://secunia.com/advisories/26105/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Insanely Simple Blog 0.x
http://secunia.com/product/14807/

DESCRIPTION:
joseph.giron13 has discovered some vulnerabilities in Insanely Simple
Blog, which can be exploited by malicious people to conduct cross-site
scripting attacks, script insertion attacks, and SQL injection
attacks.

1) Input passed to the "current_subsection" parameter in index.php is
not properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

NOTE: Other parameters are reportedly also affected.

2) Input passed to the "posted_by", "subject", and "content"
parameters in index.php 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.

3) Input passed to the "term" parameter in index.php (when "action"
is set to "search") 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 are confirmed in version 0.5. Other versions may
also be affected.

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

Use another product.
