Issue Summary

When Bitbucket repository is being added to Fisheye (via 'Bitbucket Server Repositories' tab), Fisheye is unable to clone and index it. It's caused by the fact that the private ssh key generated has file permissions which allow to read it by other users.

Steps to Reproduce

1. Install Fisheye on Windows (using its Windows installer) and Bitbucket and connect via application link
2. Access the $FISHEYE_INST directory as non-admin user (and grant permissions to this user in the process)
3. Install Git
4. Create a repository in Bitbucket and add it in Fisheye using 'Bitbucket repositories' tab

See Cause section for detailed replication steps

Expected Results

Repository is cloned and indexed.

Actual Results

Repository cloning fails because the private key is unprotected:

The below exception is thrown in the atlassian-fisheye-YYYY-MM-DD.log file:

Cause

Tested against Fisheye 4.8.13 installed on Windows 2022 DC edition
Steps performed in testing:

• non-admin user runs installer with "Run as Admin" option
• check permissions with Admin user
  
• to access this folder or even view security settings as the non-admin user Windows forces user to add themselves to the permissions (admin password is needed):
  
• the user is now listed in folder permissions:
  
• issue is now replicated:
  

The same holds true if you install as a non-admin user without the "Run as Admin" option

Conclusion, in this scenario it is not the installer but user interaction with the folder itself that leads to this issue.

Workaround

Restrict permissions of private keys stored in the `$FISHEYE_INST\data\auth` directory.

File Explorer > (right click on a file) > Properties > Security tab > Advanced

Disable inheritance > Convert inherited permissions into explicit permissions on this object

Remove any regular users - keep 'Network Service', 'SYSTEM' and the 'Administrators' group. Example:
