What is CVE-2024-42009?
CVE-2024-42009 is a Cross-Site Scripting (XSS) vulnerability found in Roundcube, an open-source webmail software that is commonly used for accessing and managing user email. The vulnerability affects versions 1.5.7 and 1.6.x up to 1.6.7, allowing for a remote attacker to exploit a desanitization issue in the message_body() function located in the program/actions/mail/show.php file. By crafting a malicious email message, an attacker can steal sensitive information from the victim and even send emails on their behalf without their consent. This vulnerability poses a serious risk, as it could compromise user accounts, facilitate phishing attacks, and undermine the overall trust in the email service provided by Roundcube.
