CVE-2024-4105Network attack vector

Script execution via reflected WEB HMI input

Published Jun 26, 2024 · Updated Aug 1, 2024

Reflected XSS in Yokogawa FAST/TOOLS and CI Server allows remote attackers to execute scripts through a malicious product URL. The WEB HMI HTTP request handler reflects attacker-controlled URL content into a page without sufficient output neutralization. FAST/TOOLS R9.01 through R10.04 and CI Server R1.01.00 through R1.03.00 are affected; execution requires a client with inadequate security measures to open the crafted URL, with script execution limited to that client.
