CVE-2023-3070Public exploitNetwork attack vector

Stored script execution via unsanitized email fields

Published Jun 2, 2023 · Updated Jan 8, 2025

Stored cross-site scripting in TSolucio coreBOS before 8 allows attackers to execute script in a user browser through saved email fields. The entity-save path accepts email values without neutralizing script-capable characters, while the user-save path likewise stores three email fields directly; the patch adds email filtering at both loci. Exploitation requires malicious email content to be saved and another user to view the resulting record, exposing that user's application session and displayed data.
