GreenBone GVM Community on KaliLinux admin password reset

 After trying all possible GVM command to get access to GUI after setup I found the only way how it worked for me. 

I have to change password directly on DB. Here are steps. And I tried to run this wihtout stopping service and it worked anyway. 

I;'m assuming that you know KALI terminal. You need 2 of them one for SQL and another for other things including HASH generation

Directly Resetting the Admin Password in PostgreSQL

1. Stop the GVM services:

   sh
   
   sudo systemctl stop gvmd
   sudo systemctl stop ospd-openvas
   

2. Access the PostgreSQL database: You need to access the gvmd database. The default user is usually postgres. Use the following command to access the PostgreSQL command line:

   sh
   
   sudo -u postgres psql gvmd
   

3. List the users in the gvmd database:

   sql
   
   SELECT name FROM users;
   

   This will list all users. Identify the admin user.

4. Reset the password: Replace admin_username with the actual username of your admin account, and newpassword with your desired password. Note that the password needs to be hashed.

   Generate a new password hash using gvmd command:

   
   sudo gvmd --user=admin_username --new-password=newpassword
   

   This should display a hash. If this does not work, you can generate the password hash using Python:

   python
   
   python3 -c "import crypt; print(crypt.crypt('newpassword', crypt.mksalt(crypt.METHOD_SHA512)))"
   

5. Update the user's password in the PostgreSQL database:

   sql
   
   UPDATE users SET password='hashed_password' WHERE name='admin_username';
   

6. Exit the PostgreSQL command line:

   sql
   
   \q
   

7. Start the GVM services again:

   sh
   
   sudo systemctl start ospd-openvas
   sudo systemctl start gvmd
   

8. Verify the Password Reset: Try logging into the GVM web interface with the new password to ensure the reset was successful.
