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
Kaifa Technology WebITR is an online attendance system, it has a vulnerability in using hard-coded encryption key. An unauthenticated remote attacker can generate valid token parameter and exploit this vulnerability to access system with arbitrary user account, including administrator’s account, to execute login account’s permissions, and obtain relevant information.

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

Kaifa Technology WebITR online attendance system contains a hard-coded encryption key vulnerability. An unauthenticated remote attacker can exploit this to generate valid authentication tokens and impersonate any user account, including administrators, thereby gaining full system access and privileges.

MitigationReplace the hard-coded encryption key with a properly managed key solution (e.g., secrets management system), rotate all existing tokens and credentials, and reset all user passwords. Implement proper key generation and secure storage mechanisms.

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. Identify installed version
    Access the system administration panel or check the application About/Help section. Alternatively, inspect the application binaries or version file (common locations include the web root directory, config folder, or footer of the web interface). Look for a version string matching '2.1.0.23'.
    Affected if The installed version is exactly 2.1.0.23.
  2. Locate configuration files
    Search the application installation directory for configuration files such as config.php, app.config, web.config, settings.xml, or any file named with 'key', 'crypto', 'encrypt', or 'auth' in the filename. Check both the web root and any backend application folders.
    Affected if A configuration file contains a hard-coded encryption key (any alphanumeric string embedded directly in the source code or config file rather than retrieved from an external secrets manager or environment variable).
  3. Inspect authentication module
    Examine the authentication or session management code files (such as auth.php, login.php, token.php, or similar) for hard-coded strings used in token generation or encryption operations. Look for static key variables or constants used for cryptographic functions.
    Affected if The code contains a hard-coded encryption key used for generating or validating authentication tokens.
  4. Verify key management practices
    Review whether the application uses environment variables, a secrets management service (e.g., HashiCorp Vault, AWS Secrets Manager), or a secure key storage mechanism for its encryption keys. Check if keys are referenced from external sources rather than defined in static files.
    Affected if Encryption keys are stored in static configuration files or source code rather than retrieved from a secure external secrets management system.

A user is affected if the Kaifa Webitr Attendance System version is 2.1.0.23 or if the application uses a hard-coded encryption key in its configuration or source code for authentication token generation.
