CVE-2026-11833
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOverview: A vulnerability has been found in FAST/TOOLS and CI Server. The web server may return a response containing the CI Server setting information. This information could be exploited by an attacker for other attacks. The affected products and versions are as follows: FAST/TOOLS (Packages: RVSVRN, UNSVRN, HMIWEB, FTEES, HMIMOB) R9.01 to R10.04 CI Server (All packages) R1.01 to R1.04
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIn FAST/TOOLS and CI Server, the web server component returns responses containing sensitive CI Server configuration/settings information. This information disclosure could allow attackers to gather reconnaissance data for launching more targeted attacks against the industrial control system environment.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify FAST/TOOLS or CI Server web server presenceCheck running processes or services for FAST/TOOLS or CI Server web server components. Look for any web service processes related to these products.Affected if FAST/TOOLS or CI Server web server component is running and accessible on the network
-
Verify web interface accessibilityDetermine if the web server is exposed to network access. Check firewall rules, network ACLs, or binding configurations to see if the web interface is reachable from untrusted networks.Affected if The web server is accessible from networks beyond the trusted internal environment
-
Inspect HTTP responses for information disclosureSend HTTP requests to the web server endpoints and examine response content. Look for any configuration data, settings, system paths, credentials, or other sensitive information returned in responses.Affected if HTTP responses contain CI Server configuration settings, system details, credentials, or other sensitive data not intended for public disclosure
-
Compare installed version to affected rangesLocate the installed version of FAST/TOOLS or CI Server using product-specific version checking methods (check product documentation for version location), then compare against vendor-published affected version ranges once available.Affected if The installed version falls within the range of affected versions published by the vendor
-
Review web service configurationExamine the web server configuration files for FAST/TOOLS or CI Server. Check for settings that control information exposure or verbose error/response modes.Affected if Web server configuration enables verbose responses or exposes detailed system information
A user is affected if FAST/TOOLS or CI Server web server is running, accessible, and returning sensitive configuration or system information in HTTP responses.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict web server access to authorized personnel only, review and harden web service configurations to prevent information leakage, and upgrade to vendor-provided patched versions when available.
