TITLE:
GoSmart Message Board SQL Injection and Cross-Site Scripting

SECUNIA ADVISORY ID:
SA12790

VERIFY ADVISORY:
http://secunia.com/advisories/12790/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
From remote

SOFTWARE:
GoSmart Message Board
http://secunia.com/product/4032/

DESCRIPTION:
Positive Technologies has reported some vulnerabilities in GoSmart
Message Board, which can be exploited by malicious people to conduct
SQL injection and cross-site scripting attacks.

1) Input passed to the parameters "QuestionNumber" and "Category" in
"Forum.asp", and the "Username" and "Password" parameters in
"Login_Exec.asp" is not 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 "Category" parameter in "Forum.asp" and the
"MainMessageID" parameter in "ReplyToQuestion.asp" isn't 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 a vulnerable site.

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

PROVIDED AND/OR DISCOVERED BY:
Positive Technologies
