Summary

Netsweeper before 4.0.11 and from 4.1.0 before 4.1.5 contains a reflected cross-site scripting flaw in the webadmin/reporter/view_server_log.php page. The log request parameter is written into the HTML response without output encoding, which is CWE-79. A remote attacker can craft a malicious URL and induce a user to open it, running JavaScript in the victim's browser session on the Netsweeper web administration interface. Shadowserver Foundation first observed exploitation evidence on 2023-10-19, and a public exploit is linked in the references.
