CVE-2026-27756
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 · uneditedSODOLA SL902-SWTGW124AS firmware versions through 200.1.20 contain a reflected cross-site scripting vulnerability in the management interface where user input is not properly encoded before output. Attackers can craft malicious URLs that execute arbitrary JavaScript in the web interface when visited by authenticated users.
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 confidenceThe SODOLA SL902-SWTGW124AS wireless gateway firmware (all versions up to 200.1.20) contains a reflected cross-site scripting vulnerability in its web-based management interface. User-supplied input in HTTP parameters is returned to the browser without proper HTML encoding, allowing attackers to inject malicious JavaScript code that executes in the context of an authenticated user's session.

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 the device modelLocate the device label or access the web management interface to confirm the model is SODOLA SL902-SWTGW124ASAffected if The device is a SODOLA SL902-SWTGW124AS gateway
-
Determine the installed firmware versionAccess the web-based management interface and navigate to the firmware or status page to read the current version number, or use the command line if accessibleAffected if The firmware version is 200.1.20 or any earlier version
-
Verify the web management interface is enabledCheck if the HTTP/HTTPS web interface is accessible on the device (typically on ports 80 or 443)Affected if The web management interface is exposed and accessible
-
Confirm authentication to the management interfaceAttempt to log into the web interface with valid administrative credentialsAffected if An authenticated session can be established with the management interface
-
Test for reflected XSS in HTTP parametersSubmit test payloads in various HTTP GET/POST parameters (such as username, search fields, or configuration values) and observe if the input is returned unencoded in the responseAffected if User-supplied input in any HTTP parameter is reflected back in the HTML response without encoding
You are affected if the device is a SODOLA SL902-SWTGW124AS running firmware version 200.1.20 or lower, and its web management interface is accessible and returns user input without HTML encoding.

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 dataImplement contextual output encoding for all user-supplied values rendered in the management interface, and release a firmware update to address this vulnerability.
