(2) Vulnerability Details:

6kbbs web application has a computer cyber security bug problem. It can be exploited by CSRF (Cross-Site Request Forgery) attacks. This may allow an attacker to trick the victim into clicking on the image to take advantage of the trust relationship between the authenticated victim and the application. Such an attack could trick the victim into creating files that may then be called via a separate CSRF attack or possibly other means, and executed in the context of their session with the application, without further prompting or verification.

Several 6kbbs products 0-day vulnerabilities have been found by some other bug hunter researchers before. 6kbbs has patched some of them. Open Sourced Vulnerability Database (OSVDB) is an independent and open-sourced database. The goal of the project is to provide accurate, detailed, current, and unbiased technical information on security vulnerabilities. The project promotes greater, open collaboration between companies and individuals. It has published suggestions, advisories, solutions details related to csrf vulnerabilities.

 

(2.1) The first code programming flaw occurs at “/portalchannel_ajax.php?” page with “&id” and &code” parameters in HTTP $POST.

(2.2) The second code programming flaw occurs at “/admin.php?” page with “&fileids” parameter in HTTP $POST.

Product Introduction Overview:

NetCat.ru is russian local company. “NetCat designed to create an absolute majority of the types of sites: from simple “business card” with a minimum content to complex web-based systems, from corporate offices to online stores, libraries or media data – in other words, projects completely different directions and at any level of complexity. View examples of sites running on NetCat CMS can be in a special section.”

“Manage the site on the basis of NetCat can even inexperienced user, because it does not require knowledge of Internet technologies, programming and markup languages. NetCat constantly improving, adds new features. In the process of finalizing necessarily take into account the wishes of our partners and clients, as well as trends in Internet development. More than 2,000 studios and private web developers have chosen for their projects is NetCat, and in 2013 sites, successfully working on our CMS, created more than 18,000.”

 

 

 

(2) Vulnerability Details:

NetCat web application has a computer security bug problem. It can be exploited by HTML Injection attacks. Hypertext Markup Language (HTML) injection, also sometimes referred to as virtual defacement, is an attack on a user made possible by an injection vulnerability in a web application. When an application does not properly handle user supplied data, an attacker can supply valid HTML, typically via a parameter value, and inject their own content into the page. This attack is typically used in conjunction with some form of social engineering, as the attack is exploiting a code-based vulnerability and a user’s trust.

Several NetCat products 0-day vulnerabilities have been found by some other bug hunter researchers before. NetCat has patched some of them. Web Security Watch is an aggregator of security reports coming from various sources. It aims to provide a single point of tracking for all publicly disclosed security issues that matter. “Its unique tagging system enables you to see a relevant set of tags associated with each security alert for a quick overview of the affected products. What’s more, you can now subscribe to an RSS feed containing the specific tags that you are interested in – you will then only receive alerts related to those tags.” It has published suggestions, advisories, solutions details related to cyber security vulnerabilities.

 

(2.1) The programming code flaw occurs at “/catalog/search.php?” page with “&q” parameter.

(2) Vulnerability Details:

 

6kbbs web application has a computer security problem. It can be exploited by weak encryption attacks. The software stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. A weak encryption scheme can be subjected to brute force attacks that have a reasonable chance of succeeding using current attack methods and resources.

 

Several 6kbbs products 0-day web cyber bugs have been found by some other bug hunter researchers before. 6kbbs has patched some of them. “The Full Disclosure mailing list is a public forum for detailed discussion of vulnerabilities and exploitation techniques, as well as tools, papers, news, and events of interest to the community. FD differs from other security lists in its open nature and support for researchers’ right to decide how to disclose their own discovered bugs. The full disclosure movement has been credited with forcing vendors to better secure their products and to publicly acknowledge and fix flaws rather than hide them. Vendor legal intimidation and censorship attempts are not tolerated here!” A great many of the web securities have been published here.

 

Source Code:

<?php

if(empty($row)){

$extrow=$db->row_select_one(“users”,”username='{$username}'”);

if(!empty($extrow) && !empty($extrow[‘salt’])){

if(md5(md5($userpass).$extrow[‘salt’])==$extrow[‘userpass’]){

$row=$extrow;

$new_row[“userpass”]=$userpass_encrypt;

$new_row[“salt”]=””;

$db->row_update(“users”,$new_row,”id={$extrow[‘id’]}”);

}

}

}

?>

 

 

Source Code From:
http://code.google.com/p/6kbbs/source/browse/trunk/convert/discuz72/loginext.php?r=16

 

We can see that “userpass” stored in cookie was encrypted using “$userpass” user password directly. And there is no “HttpOnly” attribute at all. Since md5 is used for the encryption, it is easy for hackers to break the encrypted message.

 

“The MD5 message-digest cryptography algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number. Papers about it have been published on Eurocrypt, Asiacrypt and Crypto. Meanwhile, researchers focusing on it spread in Computer Science, Computer Engineering, IEEE and Mathematics. MD5 has been utilized in a wide variety of cryptographic applications, and is also commonly used to verify data integrity. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function, MD4. The source code in RFC 1321 contains a “by attribution” RSA license.” (Wikipedia)
