Security Vulnerabilities
Nagios Fusion versions prior to R2.1 contain a vulnerability due to the application not requiring re-authentication or session rotation when a user has enabled two-factor authentication (2FA). As a result, an adversary who has obtained a valid session could continue using the active session after the target user enabled 2FA, potentially preventing the legitimate user from locking the attacker out and enabling persistent account takeover.

Nagios Log Server versions prior to 2024R2.0.2 contain a vulnerability in the AD/LDAP user import functionality as it fails to obfuscate the password field during import. As a result, the plaintext password supplied for imported accounts may be exposed in the user interface, logs, or other diagnostic output. This can leak sensitive credentials to administrators or anyone with access to import results.

Nagios Log Server versions prior to 2024R2.0.2 contain a vulnerability in the cluster manager component when requesting sensitive credentials from peer nodes over an unencrypted channel even when SSL/TLS is enabled in the product configuration. As a result, an attacker positioned on the network path can intercept credentials in transit. Captured credentials could allow the attacker to authenticate as a cluster node or service account, enabling further unauthorized access, lateral movement, or system compromise.

In Nagios Log Server versions prior to 2024R2.0.3, when a user's configured default dashboard is deleted, the application does not reliably fall back to an empty, default dashboard. In some implementations this can result in an unexpected dashboard being presented as the user's default view. Depending on the product's dashboard sharing and access policies, this behavior may cause information exposure or unexpected privilege exposure.

Nagios Log Server versions prior to 2024R2.0.3 contain an incorrect authorization vulnerability that allows non-administrator users to delete global dashboards. The application did not correctly enforce authorization checks for the global dashboard deletion workflow, enabling lower-privileged users to remove dashboards that affect other users or the overall monitoring UI.

Nagios XI versions prior to 2024R1.2 contain a command injection vulnerability in the Docker Wizard. Insufficient validation of user-supplied input in the wizard allows an authenticated administrator to inject shell metacharacters that are incorporated into backend command invocations. Successful exploitation enables arbitrary command execution with the privileges of the Nagios XI web application user.

Nagios XI versions prior to 2024R1.2.2 contain a host header injection vulnerability. The application trusts the user-supplied HTTP Host header when constructing absolute URLs without sufficient validation. An unauthenticated, remote attacker can supply a crafted Host header to poison generated links or responses, which may facilitate phishing of credentials, account recovery link hijacking, and web cache poisoning.

Nagios XI versions prior to 2024R1.3.2 contain a remote command execution vulnerability in the WinRM Configuration Wizard. Insufficient validation of user-supplied input allows an authenticated administrator to inject shell metacharacters that are incorporated into backend command invocations. Successful exploitation enables arbitrary command execution with the privileges of the Nagios XI web application user.

Nagios XI versions prior to 2024R1.0.1 contain a privilege escalation vulnerability in the System Profile component. The System Profile feature is an administrative diagnostic/configuration capability. Due to improper access controls and unsafe handling of exported/imported profile data and operations, an authenticated administrator could exploit this vulnerability to execute actions on the underlying XI host outside the application's security scope. Successful exploitation may allow an administrator to obtain root privileges on the XI server.

Nagios Log Server versions prior to 2024R1 contain a stored cross-site scripting (XSS) vulnerability where an attacker-supplied username containing JavaScript is stored and later rendered without proper encoding/escaping in admin or user-facing pages. When an authenticated victim loads the affected page, the browser executes the injected script in the victim's context.
