CVE-2023-3505Public exploitNetwork attack vector

Stored script execution via unneutralized project name

Published Jul 4, 2023 · Updated Oct 28, 2024

Stored cross-site scripting in Onest Tech CRM 1.0 allows remote authenticated users to execute script in another user's browser. The Project List Handler at /admin/project/update/2 stores the name parameter without neutralizing script markup before rendering it in a page. Project-edit access and a victim who views the affected project entry are required; successful exploitation alters browser-displayed content.
