CVE-2017-6340 — Trendmicro Interscan Web Security Virtual Appliance security vulnerability
Trend Micro InterScan Web Security Virtual Appliance (IWSVA) 6.5 before CP 1746 does not sanitize a rest/commonlog/report/template name field, which allows a 'Reports Only' user to inject malicious JavaScript while creating a new report. Additionally, IWSVA implements incorrect access control that allows any authenticated, remote user (even with low privileges like 'Auditor') to create or modify reports, and consequently take advantage of this XSS vulnerability. The JavaScript is executed when victims visit reports or auditlog pages.

Matched remediation archetype
Cross-site scripting and unsafe browser output
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
- Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
- Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.
Remediate safely
- Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
- Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
- Update affected rendering components and add tests for every output context using inert sentinel markup.
