CVE-2025-36535
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 · uneditedThe embedded web server lacks authentication and access controls, allowing unrestricted remote access. This could lead to configuration changes, operational disruption, or arbitrary code execution depending on the environment and exposed functionality.
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 confidenceAn embedded web server operates without any authentication or access control mechanisms, permitting any remote user unrestricted access. This allows attackers to modify system configurations, cause operational disruption, or execute arbitrary code depending on what functionality the server exposes.

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 embedded web server instancesScan for listening web service ports (80, 443, 8080, 8443, or custom ports) using 'netstat -tulpn' or 'ss -tulpn' and review any embedded web server documentation or services running on the systemAffected if An embedded web server is running and accessible on any network interface
-
Check authentication configurationReview the web server configuration files (e.g., config.xml, settings.conf, .ini files) for authentication-related directives such as 'auth_enabled', 'require_authentication', 'username', 'password', or similar authentication settingsAffected if No authentication is required or no authentication credentials are defined in the configuration
-
Verify access control settingsExamine the web server configuration for access control rules such as 'allow', 'deny', 'ip_whitelist', 'acl', or role-based access control (RBAC) settingsAffected if No access control rules exist or all users are granted unrestricted access
-
Confirm network exposureDetermine if the web server is bound to all interfaces (0.0.0.0) or just localhost using 'netstat' or 'ss' output, and check firewall rules that may or may not restrict accessAffected if The web server is exposed to untrusted networks without firewall protection or IP restrictions
If an embedded web server is running without authentication or access control mechanisms and is network-accessible, the environment is affected by this vulnerability.

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 authentication (e.g., username/password, token-based, or certificate-based) and role-based access control on the web server, and limit network exposure to trusted IPs or networks.
