一大早就收到一封HostMonster的邮件，标题“Hostmonster Corrected a Security Risk On Your Account.” 原来主机提供商自己也检测了timthumb漏洞，这个漏洞最近闹的人心惶惶，如果一个服务器上放了很多wordpress网站，自己查找哪个主题或者插件用了timthumb貌似真的很累，如果更新的不完全，只改了一部分，还是会被入侵。我的就是一个例子，因为乱七八糟的网站多了点，有的timthumb就给漏掉了，结果更新了一次过几天发现又被入侵了。有服务商出面解决这个问题，似乎省心多了
This is a courtesy notice that we have found and corrected exploitable timthumb.php file(s) on your account, which are listed below. While we have corrected these files, we do recommend you ensure all potential exploits are corrected on your account. This is best done by updating all scripts, plugins, modules and themes on your account to the latest version.

The timthumb.php file is a script commonly used in WordPress's (and other software's) themes and plugins to resize images. The exploit allows an attacker to arbitrarily upload and create files and/or folders on your account, which can then be used for a number of malicious tasks, including but not limited to defacement, browser high-jacking and infection, data harvesting and more. After a site has been exploited, it may lead to becoming labeled a "Malicious Website" by Google or other security authorities.
Any timthumb.php file below version 1.35, but above version 1.09 is considered vulnerable, unless patched. To prevent being compromised, we advise you update all instances of timthumb.php to version 2.0, or patch the existing vulnerable files. Note that patching the files requires more in-depth knowledge of the PHP scripting language.
The updated version of timthumb.php can be found here:
