CVE-2024-26156
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 · uneditedAll versions of ETIC Telecom Remote Access Server (RAS) prior to 4.5.0 are vulnerable to reflected cross site scripting (XSS) attacks in the method parameter. The ETIC RAS web server uses dynamic pages that gets their input from the client side and reflects the input in its response to the client.
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 · high confidenceETIC Telecom Remote Access Server versions prior to 4.5.0 contain a reflected XSS vulnerability in the 'method' parameter. The web server dynamically generates pages using client-supplied input without proper sanitization, allowing attackers to inject malicious JavaScript that executes in the victim's browser when the reflected content is displayed.

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 installed firmware versionAccess the ETIC Telecom RAS administrative interface or system settings to view the current firmware version. If CLI access is available, use the vendor-specific command to retrieve the version information.Affected if The installed firmware version is prior to 4.5.0
-
Confirm web server is enabledVerify that the RAS web interface is accessible by attempting to reach the HTTP/HTTPS endpoints typically used for remote access (such as the login page). Check network configuration to confirm the web service is listening.Affected if The web interface is enabled and reachable on the network
-
Inspect 'method' parameter handlingSend a test request to the RAS web server with a benign script payload in the 'method' parameter (for example, method=<script>alert(1)</script>). Examine the HTTP response to determine if the input is reflected back without encoding or sanitization.Affected if The 'method' parameter reflects unsanitized user input in the server response
Environment is affected if ETIC Telecom RAS firmware version is below 4.5.0 AND the web interface is enabled, allowing reflected XSS injection via the 'method' parameter.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped4.5.0
Upgrade ETIC RAS to version 4.5.0 or later to obtain the vendor patch. Until then, consider disabling the web interface or restricting network access to trusted users only.
ETIC Telecom RAS Firmware version 4.5.0
- Obtain the ETIC Telecom Remote Access Server firmware version 4.5.0 or later from the official ETIC Telecom vendor
- Access the RAS device administrative interface or console
- Navigate to the firmware update or system maintenance section
- Upload and apply the version 4.5.0 firmware file following vendor instructions
- Verify the firmware was successfully applied by checking the version in the system information
- Test that the XSS vulnerability in the method parameter is no longer exploitable
