CVE-2023-4523
CWE-79Published: September 27, 2023· Updated: Jun 17, 2026
Official Description
Real Time Automation 460 Series products with versions prior to v8.9.8 are vulnerable to cross-site scripting, which could allow an attacker to run any JavaScript reference from the URL string. If this were to occur, the gateway's HTTP interface would redirect to the main page, which is index.htm.
Technical Analysis
CVE-2023-4523 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
