TITLE:
WebspotBlogging "username" SQL Injection Vulnerability

SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/18560/

CRITICAL:
Highly critical

IMPACT:
System access, Manipulation of data, Security Bypass

WHERE:
>From remote

SOFTWARE:
WebspotBlogging 3.x
http://secunia.com/product/6893/

DESCRIPTION:
Aliaksandr Hartsuyeu has discovered a vulnerability in
WebspotBlogging, which can be exploited by malicious people to
conduct SQL injection attacks and potentially compromise a vulnerable
system.

Input passed to the "username" parameter in "login.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.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

This can further be exploited to bypass the authentication process
and access the administration section where PHP code reportedly can
be injected via the "Import Themes" functionality.

The vulnerability has been confirmed in version 3.0. Other versions
may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
Aliaksandr Hartsuyeu
