AI description

Automated description summarized from trusted sources.

CVE-2024-42009 is a Cross-Site Scripting (XSS) vulnerability affecting Roundcube webmail software, specifically versions 1.5.7 and 1.6.x up to 1.6.7. It stems from a flaw in the `message_body()` function within the `program/actions/mail/show.php` file, where a desanitization issue can be exploited. This vulnerability allows a remote attacker to steal and send emails of a victim by sending a specially crafted email message. When a user views this malicious email in Roundcube, the attacker can execute arbitrary JavaScript in the victim's browser, potentially gaining persistent access to exfiltrate emails or steal passwords.
