CVE-2024-2416
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 · uneditedCross-Site Request Forgery vulnerability in Movistar's 4G router affecting version ES_WLD71-T1_v2.0.201820. This vulnerability allows an attacker to force an end user to execute unwanted actions in a web application in which they are currently authenticated.
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 confidenceCross-Site Request Forgery vulnerability in the web management interface of the Movistar 4G router (ES_WLD71-T1_v2.0.201820). The vulnerability allows remote attackers to trick authenticated users into unknowingly submitting malicious requests to the router's web application, potentially enabling unauthorized configuration changes or administrative actions.

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 router firmware versionAccess the router web interface or check the device label/model number. The affected version is ES_WLD71-T1_v2.0.201820.Affected if The firmware version exactly matches ES_WLD71-T1_v2.0.201820
-
Confirm web management interface is activeAccess the router admin panel via its IP address (commonly 192.168.1.1 or 192.168.0.1) in a browser. Check if login page loads.Affected if The web management interface is accessible and responds to requests
-
Inspect form submissions for anti-CSRF tokensLog into the router admin panel, view page source (right-click > View Page Source) or use browser developer tools (F12 > Network tab) to examine state-changing forms (e.g., WiFi settings, admin password, port forwarding). Look for hidden input fields containing token values or Authorization headers in requests.Affected if Forms lack hidden CSRF token fields or the requests do not include anti-CSRF tokens in headers/parameters
-
Verify session cookie SameSite attributeWith browser developer tools open, log into the router and inspect the Set-Cookie headers in the response. Check if the session cookie includes the SameSite attribute (e.g., SameSite=Strict or SameSite=Lax).Affected if Session cookies do not have SameSite attribute set, or SameSite=None is used without Secure flag
-
Test Origin/Referer header validationAttempt to submit a form request with a mismatched or missing Origin/Referer header (requiresBurp Suite or similar proxy). Observe if the request is accepted or rejected by the server.Affected if The router accepts requests with missing or mismatched Origin/Referer headers, indicating lack of proper validation
You are affected if your router runs firmware version ES_WLD71-T1_v2.0.201820 and its web management interface forms lack anti-CSRF tokens, do not enforce SameSite cookies, or do not validate Origin/Referer headers.
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.
From vendor dataImplement anti-CSRF tokens on all state-changing forms and validate Origin/Referer headers server-side; also set SameSite attribute on session cookies. End users should avoid browsing untrusted sites while logged into router admin interfaces.
