The remote web server is running Roundcube Webmail version 1.5.x prior to 1.5.8 or 1.6.x prior to 1.6.8. It is, therefore, affected by multiple vulnerabilities.

  - A Cross-Site Scripting vulnerability in rcmail_action_mail_get->run() in Roundcube through 1.5.7 and 1.6.x   through 1.6.7 allows a remote attacker to steal and send emails of a victim via a malicious e-mail   attachment served with a dangerous Content-Type header. (CVE-2024-42008)

  - A Cross-Site Scripting vulnerability in Roundcube through 1.5.7 and 1.6.x through 1.6.7 allows a remote   attacker to steal and send emails of a victim via a crafted e-mail message that abuses a Desanitization   issue in message_body() in program/actions/mail/show.php. (CVE-2024-42009)

  - mod_css_styles in Roundcube through 1.5.7 and 1.6.x through 1.6.7 allows a insufficiently filters   Cascading Style Sheets (CSS) token sequences in rendered e-mail messages, allowing a remote attacker to   obtain sensitive information. (CVE-2024-42010)
