What is CVE-2025-34270?

The Nagios Log Server prior to version 2024R2.0.2 has a security flaw in its Active Directory/LDAP user import functionality that fails to adequately obfuscate the password field during the import process. This oversight means that plaintext passwords provided for imported accounts may become visible within the user interface, logs, or other system outputs. Consequently, this could potentially allow sensitive user credentials to be accessed by administrators or any individual who has access to the import results, posing significant security risks.
