Security Vulnerabilities
Nagios Network Analyzer versions prior to 2024R1 contain a stored cross-site scripting (XSS) vulnerability in the Source Groups page (percentile calculator menu). An attacker can supply a malicious payload which is stored by the application and later rendered in the context of other users. When a victim views the affected page the injected script executes in the victim's browser context.

Nagios Network Analyzer versions prior to 2024R2.0.1 contain a vulnerability in the LDAP certificate management functionality whereby the certificate removal operation fails to apply adequate input sanitation. An authenticated administrator can trigger command execution on the underlying host in the context of the web application service, resulting in remote code execution with the service's privileges.

Nagios XI versions prior to 2024R2 contain a command injection vulnerability in the WinRM plugin. Insufficient validation of user-supplied parameters 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 and can be leveraged to modify configuration, exfiltrate data, disrupt monitoring operations, or execute commands on the underlying host operating system.

Nagios XI versions prior to 2026R1 contain a remote code execution vulnerability in the Core Config Manager (CCM) Run Check command. Insufficient validation/escaping of parameters used to build backend command lines allows an authenticated administrator to inject shell metacharacters that are executed on the server. Successful exploitation results in arbitrary command execution with the privileges of the Nagios XI web application user and can be leveraged to gain control of the underlying host operating system.

Nagios XI versions prior to 2024R1.4.2 configure some systemd unit files with permission sets that were too permissive. In particular, the nagios.service unit had executable permissions that were not required. Overly permissive permissions on service unit files can broaden local attack surface by enabling unintended execution behaviors or facilitating abuse of service operations when combined with other weaknesses.

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.
