CVE-2020-6091
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 · uneditedAn exploitable authentication bypass vulnerability exists in the ESPON Web Control functionality of Epson EB-1470Ui MAIN: 98009273ESWWV107 MAIN2: 8X7325WWV303. A specially crafted series of HTTP requests can cause authentication bypass resulting in information disclosure. An attacker can send an HTTP request to trigger this vulnerability.
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 confidenceThis is an authentication bypass vulnerability in the web-based management interface (Web Control) of the Epson EB-1470Ui interactive projector. The vulnerability allows unauthenticated attackers to bypass authentication checks through specially crafted HTTP requests, enabling access to sensitive information without proper credentials.

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 projector modelCheck the physical device label or access the projector's on-screen display menu to confirm the exact model number is Epson EB-1470UiAffected if The device model is confirmed to be Epson EB-1470Ui
-
Check if Web Control is enabled and accessibleAccess the projector's network settings through the on-screen menu or physical buttons to verify if the web-based management interface (Web Control) is enabled. Note the IP address assigned to the projector.Affected if Web Control is enabled and the projector has a network IP address
-
Verify unauthenticated HTTP access to the management interfaceFrom a computer on the same network, open a web browser and navigate to http://[projector-ip-address] or http://[projector-ip-address]/cgi-bin/webconf.exe without providing any login credentials. Observe whether the management interface loads or returns sensitive information.Affected if The web interface loads or exposes any content without requiring authentication credentials
-
Test for authentication bypass on sensitive endpointsTry accessing common management endpoints such as /cgi-bin/webconf.exe, /cgi-bin/login.exe, or /general/status.html without authenticating. Check if sensitive configuration pages, system information, or network settings are accessible.Affected if Any sensitive management pages or configuration data is accessible without authentication
If you have an Epson EB-1470Ui projector with Web Control enabled and the management interface is accessible without authentication credentials, your environment is affected by this CVE.
