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
CloudClassroom-PHP-Project v1.0 is affected by an insecure credential transmission vulnerability. The application transmits passwords over unencrypted HTTP during the login process, exposing sensitive credentials to potential interception by network-based attackers. A remote attacker with access to the same network (e.g., public Wi-Fi or compromised router) can capture login credentials via Man-in-the-Middle (MitM) techniques. If the attacker subsequently uses the credentials to log in and exploit administrative functions (e.g., file upload), this may lead to remote code execution depending on the environment.

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

CloudClassroom-PHP-Project v1.0 transmits user passwords in plaintext over unencrypted HTTP during the login process. An attacker on the same network can perform a Man-in-the-Middle attack to intercept these credentials, potentially gaining administrative access and exploiting functions like file upload for remote code execution.

MitigationImplement TLS/SSL (HTTPS) for all login pages and sensitive endpoints to encrypt credential transmission in transit.

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 installed product version
    Identify the CloudClassroom PHP Project installation and verify its version number is 1.0. Check for version files, about pages, or headers that display the software version.
    Affected if The installed version is Vishalmathur Cloudclassroom Php Project version 1.0
  2. Check if HTTP access is enabled
    Attempt to access the login page over HTTP (port 80) for the CloudClassroom application. Use a browser or curl command: curl http://[target]/login or the equivalent login path.
    Affected if The login page is reachable over HTTP (unencrypted port 80)
  3. Verify HTTPS is not enforced for login
    Examine the web server configuration (Apache, Nginx, or IIS) and the application login form action URLs. Check if the form submits to an http:// URL instead of https://.
    Affected if The login form action uses an http:// URL or no HTTPS redirect is configured
  4. Inspect credential transmission method
    Use a local proxy (such as Burp Suite or OWASP ZAP) or network capture tool to intercept the login request. Observe whether the password parameter is sent in plaintext within the HTTP POST body.
    Affected if The password is transmitted in plaintext within an unencrypted HTTP request

If the login page is accessible over HTTP and credentials are sent without SSL/TLS encryption, the environment is affected by this vulnerability.
