 近日，互联网上公布了一例关于“CmsEasy”的上传漏洞，并给出了攻击程序，经SCANV网站安全中心研究人员分析后确认，漏洞确实存在，到本文发布为止，官方还未推出任何防御补丁，该漏洞属于“0day”高危漏洞。攻击者利用该漏洞可以直接上传恶意文件，并最终导致网站被“脱裤”、“挂马”及“非法SEO”等危险。目前我们已经把漏洞细节报告给CmsEasy官方,请广大站长朋友注意留意CmsEasy官方动态，以及我们的微博，同时复查网站安全状态，启用临时安全补丁（详见下）。

关于CmsEasy
       CmsEasy是国内一款使用PHP+MySQL技术开发的企业网站程序，是国内比较常见的CMS程序之一，由于其使用广泛、用户数量大，也成为“黑客”密切关注的对象！

if (!$new_name ||!preg_match('/\.(jpg|gif|png|bmp)$/',$new_name)) 
{ 
       return false; 
} 

名词解释
       0day漏洞：是指已经被发现（有可能未被公开）而官方还未发布相关补丁的漏洞。
