Roundcube Webmail
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Roundcube Webmail 在 1.6.20 之前以及 1.7.x 系列中 1.7.5 之前的版本，均存在邮件头注入漏洞。其中， 方法直接使用了来自内联图像数据 URI 的媒体类型，而未对其进行验证。因此，远程已认证攻击者可通过在该媒体类型中插入 CRLF 序列，将任意 MIME 部分头注入到发出的邮件中。上游已在提交"Fix mail header injection via media type in an inline image data URI"中修复此问题，该修复通过调用 对媒体类型进行了验证。

Vulnerability Description
Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability. rcmail_sendmail::extract_inline_images() used the media type taken from an inline image data URI without validating it, so a remote authenticated attacker could inject arbitrary MIME part headers into the outgoing message by placing CRLF sequences in that media type. Upstream fixed this in the commit “Fix mail header injection via media type in an inline image data URI”, which validates the media type with rcube_mime::is_mimetype_valid().
