CVE-2024-37679Public exploitNetwork attack vector

Browser script execution via reflected myclient parameter

Published Jun 24, 2024 · Updated Aug 2, 2024

Cross-site scripting in FineSoft before 8.0 allows remote attackers to execute scripts in a user's browser through the myclient parameter. The login error page reflects the user-controlled myclient URL parameter into its HTML response without neutralizing executable markup. Exploitation requires a user to load the crafted error response, allowing script execution and browser-context data access or actions.
