🔒 Mitigate CVE-2025-26465 with an Automated SSH Configuration Update
This mitigation script automatically secures your OpenSSH client by backing up and modifying the SSH configuration to disable the vulnerable “VerifyHostKeyDNS” option, protecting your SSH sessions from potential man-in-the-middle attacks.
🔍 How it works:
It first retrieves and checks your OpenSSH version to confirm it falls within the vulnerable range.
The script backs up the global configuration file (typically /etc/ssh/ssh_config) to ensure you have a recovery point.
It then searches for any instance of “VerifyHostKeyDNS” set to “yes” or “ask” and modifies those lines to “no”.
The update is applied seamlessly so you can verify that the vulnerability is mitigated without manual edits.
⚠️ Why it matters:
By automatically disabling the risky DNS-based host key verification setting, this script prevents attackers from exploiting CVE-2025-26465 to impersonate SSH servers. Keeping your SSH configuration secure is essential to safeguard sensitive data and maintain the integrity of remote management sessions.
