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
HAMweather 2.x allows remote attackers to modify administrative settings and obtain sensitive information via a direct request to hwadmin.cgi.

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 confidence

HAMweather 2.x contains an authentication bypass vulnerability in the hwadmin.cgi administrative script. The script can be accessed directly without proper authentication, allowing remote attackers to modify administrative settings and retrieve sensitive information by issuing direct HTTP requests to the admin interface.

MitigationRestrict access to hwadmin.cgi through web server authentication (e.g., .htaccess, IP restrictions) or implement proper session-based authentication within the script itself. If the product is no longer supported, consider migrating to a maintained weather software solution.

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. Locate the hwadmin.cgi script
    Search the web server document root for the hwadmin.cgi file, typically in the /cgi-bin/ or same directory as the main HAMweather installation
    Affected if The file exists on the server
  2. Verify direct HTTP access to hwadmin.cgi
    Send an HTTP GET request to the hwadmin.cgi URL (for example, http://yourserver.com/cgi-bin/hwadmin.cgi) without providing any authentication credentials or session cookies
    Affected if The script responds with administrative functionality or login prompts without requiring authentication
  3. Check for web server access controls
    Examine the web server configuration (such as .htaccess files or Apache config) for any rules restricting access to hwadmin.cgi
    Affected if No access restrictions are configured for hwadmin.cgi, or the script ignores such restrictions
  4. Inspect admin functionality without credentials
    If hwadmin.cgi responds, attempt to access administrative features (such as viewing settings or configuration pages) by issuing direct HTTP requests to the script
    Affected if Administrative features are accessible without any form of authentication

If hwadmin.cgi exists and responds to direct HTTP requests without requiring any authentication, the environment is affected by this vulnerability.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict access to hwadmin.cgi through web server authentication (e.g., .htaccess, IP restrictions) or implement proper session-based authentication within the script itself. If the product is no longer supported, consider migrating to a maintained weather software solution.
