CVE-2024-51320Public exploitNetwork attack vector

Stored script execution via inline HTML attachments

Published Mar 11, 2025 · Updated Mar 11, 2025

Stored XSS in Zucchetti Ad Hoc Infinity 2.4 allows remote authenticated users to execute script in another user's browser through an HTML invoice attachment. The gsdm_fsave_htmltmp servlet stores attacker-supplied HTML as an invoice attachment, and gsdm_btlk_openfile serves it inline in an iframe without neutralizing scripts. Exploitation requires permission to add invoice attachments and a user to open the file; the script runs in the viewer's authenticated browser context.
