CVE-2025-34270Network attack vector

Credential disclosure via unobfuscated AD/LDAP import passwords

Published Oct 30, 2025 · Updated Nov 17, 2025

Credential exposure in Nagios Log Server before 2024R2.0.2 allows remote authenticated users to read AD/LDAP import passwords. The administrative import workflow renders or records the supplied directory password without proper obfuscation, exposing plaintext in its interface, logs, or diagnostics. Administrative access to import results or related diagnostic output is required, and exposure is limited to submitted credentials.
