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 · unedited
LiteWEB 2.7 allows remote attackers to cause a denial of service (hang) via a large number of requests for nonexistent pages.

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 confidence

LiteWEB 2.7 web server contains a denial of service vulnerability where the server hangs when receiving a large number of requests for nonexistent pages. This suggests improper resource management or lack of cleanup for 404 error handling under high request loads.

MitigationImplement proper resource cleanup and request timeouts for invalid page requests, or deploy a reverse proxy/WAF with rate limiting in front of LiteWEB to filter excessive requests.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm LiteWEB web server is installed
    Check running processes for 'liteweb' or check installed programs for Perception Liteweb. Also check if port 80 or common HTTP ports are listening with LiteWEB as the service.
    Affected if LiteWEB 2.7 is installed and running as a web server
  2. Verify the installed version
    Check the version of LiteWEB by examining the binary, service properties, or headers returned by the web server using a tool like curl or netcat.
    Affected if The version is exactly 2.7
  3. Determine network exposure
    Check firewall rules and network configuration to determine if the LiteWEB server is accessible from network sources.
    Affected if LiteWEB is exposed to network traffic without rate limiting protection
  4. Assess request handling capacity
    Review server configuration files or logs to understand request handling behavior for nonexistent pages (404 responses).
    Affected if The server handles 404 responses without resource cleanup limits configured

A user is affected if LiteWEB version 2.7 is running and accessible over the network, as the vulnerability triggers when receiving a large volume of requests for nonexistent pages.
