CVE-2024-48906Public exploitNetwork attack vector

E-mail disclosure via unsanitized attachment filename

Published May 1, 2025 · Updated May 6, 2025

Stored XSS in Sematell ReplyOne 7.4.3.0 allows remote attackers to execute script via a crafted ReplyDesk e-mail attachment name. The ReplyDesk web interface renders an unsanitized attachment filename as active HTML and triggers its event-handler payload when a user hovers over the name. An external sender needs only to deliver the e-mail and wait for a ReplyDesk user to hover over the attachment; the script can read and exfiltrate other e-mails.
