(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:

NetCat web application has a computer security bug problem. It can be exploited by HTTP Response Splitting (CRLF) attacks. This could allow a remote attacker to insert arbitrary HTTP headers, which are included in a response sent to the server. If an application does not properly filter such a request, it could be used to inject additional headers that manipulate cookies, authentication status, or more.

Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. NetCat has patched some of them. CXSECurity is a huge collection of information on data communications safety. Its main objective is to inform about errors in various applications. It also publishes suggestions, advisories, solutions details related to CRLF vulnerabilities and cyber intelligence recommendations.

(2.1) The first code flaw occurs at “/post.php” page with “redirect_url” parameter by adding “%0d%0a%20”.

(2) ASP Version: 6kbbs (6k Forum) is an excellent community forum process . The program is simple but not simple ; fast , small ; interface generous and good scalability ; functional and practical . pursue superiority , good interface , practical functions of choice for subscribers.”

 

 

 

(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)

FC2 Online Web Service Open Redirect (Unvalidated Redirects and Forwards) Cyber Security Vulnerabilities

 

Domain:
fc2.com

“FC2 (founded July 20, 1999) is a popular Japanese blogging host, the third most popular video hosting service in Japan (after YouTube and Niconico), and a web hosting company headquartered in Las Vegas, Nevada. It is the sixth most popular website in Japan overall (as of January 2014). FC2 is an abbreviation of “Fantastic Kupi-Kupi (クピクピ)”. It is known to allow controversial adult content such as pornography and hate speech (unlike many of its competitors). The company uses rented office space for its headquarters which it shares with many other U.S.-based businesses. It also pays taxes in the United States. The physical servers are located in the United States. However, it is believed that the majority of the company and its users (including employees) are located within Japan” (Wikipedia)

 

The Alexa rank of fc2.com is 52 on February 18 2015. It is the toppest Japanese local website sevice.

 

 

 

(1) Vulnerability Description:

FC2 online web service has a computer cyber security bug problem. It can be exploited by Open Redirect (Unvalidated Redirects and Forwards) attacks. Here is the description of Open Redirect: “An open redirect is an application that takes a parameter and redirects a user to the parameter value without any validation. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it.” One consequences of it is Phishing. (OWASP)

 

The program code flaw can be attacked without user login. Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 7, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2),Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.

 

In fact, during the test, it is not hard to find URL Redirection bugs in FC2. Maybe fc2.com pays little attention to mitigate these Vulnerabilities. These bugs were found by using URFDS.

 

 

 

(2) Use one of webpages for the following tests. The webpage address is “http://securitypost.tumblr.com/“. Can suppose that this webpage is malicious.

 

 

Vulnerability Disclosure:
Those vulnerabilities were reported to Rakuten, they are still unpatched.

fc2.comのAlexaのランクはそれがtoppest日本のローカルウェブサイトの流通サービスである2月18日2015年52あります。

 

 

 

(1)脆弱性の説明:

FC2オンラインWebサービスは、コンピュータのサイバーセキュリティバグの問題があります。それは、オープンリダイレクト(未検証のリダイレクトとフォワード)攻撃によって悪用される可能性があります。ここでオープンリダイレクトの説明は次のとおりです。「オープンリダイレクトがパラメータを受け取り、何の検証も行わずにパラメータ値にユーザーをリダイレクトするアプリケーションです。この脆弱性は、それを実現することなく、悪質なサイトを訪問するユーザーを取得するためにフィッシング攻撃で使用されています。。 “それの一つの結果はフィッシングで​​す。 (OWASP)

 

プログラムコードの欠陥は、ユーザのログインなしで攻撃される可能性があります。テストは、Windows 7のMicrosoftのIE(9 9.0.8112.16421)で行われた、Mozilla Firefoxの(37.0.2)&グーグルクロム42.0.2311のUbuntuの(64ビット)(14.04.2)はMac OSのアップルのSafari 6.1.6 X v10.9マーベリックス。

 

実際には、テスト時には、FC2内のURLリダイレクトのバグを見つけることは難しいことではありません。多分fc2.comは、これらの脆弱性を軽減するためにはほとんど注意を払っています。

(1) Vulnerability description:

FC2 has a computer cyber security bug problem. It is vulnerable to XSS attacks. Here is the description of XSS: “Hackers are constantly experimenting with a wide repertoire of hacking techniques to compromise websites and web applications and make off with a treasure trove of sensitive data including credit card numbers, social security numbers and even medical records. Cross-site Scripting (also known as XSS or CSS) is generally believed to be one of the most common application layer hacking techniques Cross-site Scripting allows an attacker to embed malicious JavaScript, VBScript, ActiveX, HTML, or Flash into a vulnerable dynamic page to fool the user, executing the script on his machine in order to gather data. The use of XSS might compromise private information, manipulate or steal cookies, create requests that can be mistaken for those of a valid user, or execute malicious code on the end-user systems. The data is usually formatted as a hyperlink containing malicious content and which is distributed over any possible means on the internet.” (Acunetix)

 

The programming code flaw occurs at fc2 URLs’ filenames . Fc2 only filter part of the filenames in the urls. Almost all urls are affected under domain blog.fc2.com/tag are affected. i.e.
