CVE-2023-4892Public exploitNetwork attack vector

Stored script execution via preserved HTML event handlers

Published Sep 25, 2023 · Updated Sep 24, 2024

Stored cross-site scripting in Sismics Teedy 1.11 allows remote authenticated users to run JavaScript when another user edits a document. The document text editor stores attacker-supplied HTML event-handler attributes without neutralizing them and executes the handler when the saved document is reopened for editing. An account is required to create the document, and a victim must edit it; execution in the victim's session can expose cookies and private documents.
