CVE-2025-60737 Overview
CVE-2025-60737 is a Cross-Site Scripting (XSS) vulnerability affecting the Ilevia EVE X1 Server, a home and building automation controller. The flaw resides in the /index.php component of the device's web management interface. A remote, unauthenticated attacker can inject arbitrary script content that executes in the context of a victim's browser when the crafted request is processed. The vulnerability is tracked under CWE-79: Improper Neutralization of Input During Web Page Generation.
Critical Impact
Successful exploitation allows attackers to execute arbitrary script in an authenticated user's browser session, enabling session hijacking, credential theft, or unauthorized control of the automation server.
Affected Products
- Ilevia EVE X1 Server Firmware versions <= 4.7.18.0.eden
- Ilevia EVE X1 Server Logic Version <= 6.00 - 2025_07_21
- Ilevia EVE X1 Server hardware appliance

Technical Details for CVE-2025-60737
Vulnerability Analysis
The Ilevia EVE X1 Server exposes a PHP-based web management interface used to configure automation logic, scenes, and connected devices. The /index.php endpoint fails to properly neutralize user-controllable input before reflecting it into the HTTP response. An attacker crafts a URL or form submission containing HTML or JavaScript payloads. When a targeted user, typically an administrator, interacts with the malicious link, the payload runs in the browser under the origin of the vulnerable server.
Because the affected component is a controller for physical building systems, script execution in an administrator session can be used to manipulate device state, harvest configuration data, or pivot to internal network resources reachable by the server.
Root Cause
The root cause is missing or insufficient output encoding on parameters processed by /index.php. User input flows into HTML response contexts without contextual escaping, allowing script tags and event handlers to break out of intended data contexts and execute as code.
Attack Vector
Exploitation is network-based and requires user interaction. The attacker delivers a crafted link, typically via phishing, and relies on a logged-in administrator clicking it. No authentication is required from the attacker to construct the payload, and the scope changes when the injected script accesses resources beyond the vulnerable component. A proof-of-concept repository is available on GitHub.

Detection Methods for CVE-2025-60737
Indicators of Compromise
- HTTP requests to /index.php containing URL-encoded <script>, javascript:, or event handler attributes such as onerror= and onload=.
- Outbound connections from administrator workstations to attacker-controlled domains immediately following EVE X1 web interface access.
- Unexpected configuration changes to automation logic, users, or scenes on the EVE X1 Server without matching audit log entries.
Detection Strategies
- Deploy a web application firewall (WAF) rule set in front of the EVE X1 management interface to flag reflected script patterns targeting /index.php.
- Inspect web server access logs for anomalous query strings that combine HTML metacharacters (<, >, ") with common XSS keywords.
- Correlate administrator browser telemetry with device access logs to identify sessions that loaded external scripts from non-vendor origins.
Monitoring Recommendations
- Enable verbose HTTP access logging on the EVE X1 Server and forward logs to a centralized SIEM or data lake for retention and query.
- Alert on any successful authentication to the EVE X1 web interface followed by configuration write operations within a short time window.
- Monitor the network segment hosting the controller for lateral movement attempts originating from the device itself.
How to Mitigate CVE-2025-60737
Immediate Actions Required
- Restrict access to the EVE X1 web management interface to trusted management networks using firewall rules or VLAN segmentation.
- Instruct administrators to log out of the web interface when not actively managing the device to reduce the window for reflected XSS abuse.
- Warn operators against clicking links to the EVE X1 server received via email, chat, or untrusted web pages.
Patch Information
No vendor advisory or fixed firmware version is currently referenced in the NVD record for CVE-2025-60737. Users should contact Ilevia directly for updated firmware beyond 4.7.18.0.eden and Logic Version 6.00 - 2025_07_21, and monitor the vendor product page for release notes.
Workarounds
- Place the EVE X1 Server behind a reverse proxy or WAF that strips or encodes HTML metacharacters in query strings and form fields targeting /index.php.
- Enforce a strict Content Security Policy (CSP) at the proxy layer to block inline script execution and disallow external script sources.
- Disable remote access to the management interface from the internet, requiring VPN connectivity for administrative sessions.
# Example iptables rule restricting management interface access to a trusted subnet
iptables -A INPUT -p tcp --dport 80 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
