The Fedora Nagios package uses "nagiosadmin" as the default password for the "nagiosadmin" administrator account, which makes it easier for remote attackers to obtain access by leveraging knowledge of the credentials.

Security readout for executives and security teams

Plain-English summary

This CVE describes Fedora’s Nagios package shipping the Nagios web administrator account with a known default password, "nagiosadmin." If a deployed Nagios instance kept that credential and was reachable, an attacker could gain administrative access. The sources do not provide CVSS, affected versions, or patch details.

Executive priority

Treat this as a quick hygiene issue with meaningful access risk. Prioritize externally reachable Nagios systems first, then internal monitoring servers. The urgency depends on whether default credentials remain in use.

Technical view

CVE-2016-0726 is a default-credential issue in the Fedora Nagios package: the nagiosadmin administrator account used the nagiosadmin default password. The record indicates remote attackers could leverage credential knowledge to obtain access. No CPEs, version ranges, CWE, CVSS vector, or vendor fix details are included in the provided sources.

Likely exposure

Exposure is most likely on Fedora systems that installed the affected Nagios package and left the default nagiosadmin credentials unchanged, especially if the Nagios web interface is reachable from untrusted networks.

Exploitation context

The CVE record supports remote access risk through known credentials. The source bundle does not show CISA KEV listing, active exploitation, public exploit tooling, or confirmed compromise activity.

Researcher notes

The public CVE data is sparse. It identifies the issue as Fedora Nagios default credentials but omits affected versions, package advisory details, scoring, and fixed build information. Avoid broad product claims beyond Fedora Nagios unless vendor records confirm them.

Mitigation direction

  • Identify Fedora-hosted Nagios deployments and ownership.
  • Change any default nagiosadmin credentials immediately.
  • Restrict Nagios web access to trusted networks or VPN.
  • Review Red Hat or Fedora vendor guidance for package-specific remediation.
  • Disable or rename unused default administrator accounts where supported.

Validation and detection

  • Check whether Nagios is installed from Fedora packages.
  • Confirm the nagiosadmin password is not the documented default.
  • Verify Nagios is not exposed directly to the internet.
  • Review authentication logs for unexpected nagiosadmin access.
  • Confirm access controls require trusted network paths.
