CVE-2026-10058 Overview
CVE-2026-10058 is a Stored Cross-Site Scripting (XSS) vulnerability in the ITS Intelligent SCADA System developed by ITP Technology. Privileged remote attackers can inject persistent JavaScript that executes in users' browsers when affected pages are loaded. The flaw is tracked under CWE-79 (Improper Neutralization of Input During Web Page Generation). Because the system is used in Supervisory Control and Data Acquisition (SCADA) environments, script execution within an operator session could expose sensitive control interfaces to attacker-controlled code.
Critical Impact
Authenticated attackers with high privileges can store malicious JavaScript that executes in operator browsers, enabling session theft and user interface manipulation in an industrial control environment.

Technical Details for CVE-2026-10058
Vulnerability Analysis
The ITS Intelligent SCADA System fails to neutralize user-supplied input before storing and rendering it in the application interface. An authenticated attacker holding high privileges can submit JavaScript payloads through input fields that the application persists. When another user loads the affected page, the browser executes the stored script in the context of that user's session.
The attack requires user interaction, as the payload triggers when a victim navigates to the affected view. Despite the requirement for privileged access and victim participation, the persistent nature of stored XSS allows the payload to remain active across sessions until removed.
Exploitation in a SCADA context raises operational concerns. Operator consoles often display real-time process data and accept control commands, so script execution inside an authenticated session could read interface contents, exfiltrate session tokens, or alter the rendered view to mislead operators.
Root Cause
The root cause is missing output encoding and input sanitization on data persisted by the application. User input reaches the rendered HTML context without contextual escaping, allowing <script> tags or event handlers to be interpreted as code rather than data.
Attack Vector
The attack vector is network-based and requires an authenticated session with high privileges. The attacker submits a payload through an input field that stores the data server-side. A second user with access to the affected page triggers execution when their browser renders the unsanitized content. Refer to the TW-CERT Security Advisory for vendor-published technical context.
Detection Methods for CVE-2026-10058
Indicators of Compromise
- Unexpected <script> tags, javascript: URIs, or on* event handler attributes stored in SCADA configuration fields, labels, or comment fields.
- Outbound HTTP requests from operator workstations to unknown domains shortly after loading SCADA management pages.
- Anomalous session activity or privilege use following operator visits to pages modified by privileged accounts.
Detection Strategies
- Review application database tables and configuration stores for HTML or JavaScript syntax in fields expected to hold plain text.
- Inspect web server access logs for POST requests from privileged accounts containing encoded script payloads such as %3Cscript%3E or onerror=.
- Monitor browser Content Security Policy (CSP) violation reports if CSP is enforced on the SCADA web interface.
Monitoring Recommendations
- Enable audit logging for all changes to entities rendered in the SCADA user interface, including the originating account and source IP.
- Alert on administrative account logins from new geographic locations or off-hours sessions that subsequently modify displayable fields.
- Correlate operator workstation browser telemetry with SCADA configuration changes to identify suspicious sequences.
How to Mitigate CVE-2026-10058
Immediate Actions Required
- Restrict administrative access to the ITS Intelligent SCADA System to a minimal set of accounts and enforce multi-factor authentication.
- Audit existing stored content for embedded HTML or JavaScript and remove any unauthorized entries.
- Segment SCADA web management interfaces from general corporate networks and limit access to engineering workstations.
Patch Information
Consult the TW-CERT Security Advisory and the TW-CERT Incident Report for vendor remediation guidance. Apply the fixed version supplied by ITP Technology once available and verify that input sanitization is enforced on all user-controllable fields.
Workarounds
- Deploy a Content Security Policy that disallows inline scripts and restricts script sources on the SCADA web interface.
- Use a reverse proxy or web application firewall (WAF) rule to block requests containing script tags or common XSS payload patterns to administrative endpoints.
- Reduce the number of accounts with the elevated privileges required to store affected fields, and review their activity regularly.
