Default Credentials in Lenve VHR 1.0-SNAPSHOT

Executive Summary

This vulnerability is in lenve vhr 1.0-SNAPSHOT where default credentials are hardcoded in the vhr.sql file. The admin, libai, and hanyu accounts use the password '123' with BCrypt hashing. Attackers can exploit this by using the default login endpoint to gain administrative access without authentication.

Detection Guidance

Check if the vhr application version 1.0-SNAPSHOT is deployed by inspecting the vhr.sql file for default INSERT statements for admin, libai, or hanyu accounts with passwords set to '123'. Verify if BCrypt hashes match known default values. Test login attempts to the default endpoint using these credentials.

Commands: 1) grep -i "INSERT.*admin.*123" /path/to/vhr.sql 2) curl -X POST http://<target>/login -d '{"username":"admin","password":"123"}' 3) Check application logs for successful admin logins without prior password setup.

Impact Analysis

An attacker could gain full administrative access to the vhr application, allowing them to read, modify, or delete sensitive data. Since the exploit is publicly available, the risk of unauthorized access is high, especially if the application is deployed with default settings.

Mitigation Strategies

Remove or modify the vhr.sql file to randomize default passwords and enforce a password change on first login. Update all default accounts (admin, libai, hanyu) to strong, unique passwords. Restrict access to the login endpoint until remediation is complete.
