The vulnerability requires no privileges but does require user interaction. While no known exploits are currently reported in the wild, the flaw could compromise user sessions and data integrity. European organizations using vulnerable Nagios XI versions should prioritize patching to mitigate potential attacks. The vulnerability's CVSS score is 5.1, reflecting moderate risk due to ease of exploitation and impact on confidentiality and integrity.
Nagios XI versions prior to 2024R1 contain a missing access control vulnerability via the Web SSH Terminal. A remote, low-privileged attacker could access or interact with the terminal interface without sufficient authorization, potentially allowing unauthorized command execution or disclosure of sensitive information.
Nagios XI versions prior to 2024R1.1.3 did not invalidate all other active sessions for a user when that user's password was changed. As a result, any pre-existing sessions (including those potentially controlled by an attacker) remained valid after a credential update. This insufficient session expiration could allow continued unauthorized access to user data and actions even after a password change.
Nagios XI versions prior to < 2024R1.1.2 are vulnerable to a reflected cross-site scripting (XSS) via the login page when accessed with older web browsers. Insufficient validation or escaping of user-supplied input reflected by the login page can allow an attacker to craft a malicious link that, when visited by a victim, executes arbitrary JavaScript in the victim’s browser within the Nagios XI origin. The issue is observable under legacy browser behaviors; modern browsers may mitigate some vectors.
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 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 2024R1.2 are vulnerable to remote code execution (RCE) through its NRDP (Nagios Remote Data Processor) server plugins. Insufficient validation of inbound NRDP request parameters allows crafted input to reach command execution paths, enabling attackers to execute arbitrary commands on the underlying host in the context of the web/Nagios service.
Nagios XI versions prior to 2024R1.4.2 contain a remote code execution vulnerability in the Business Process Intelligence (BPI) component. Insufficient validation and sanitization of administrator-controlled BPI configuration parameters (notably bpi_logfile and bpi_configfile) allow an authenticated administrative user to cause the product to create or overwrite files within the webroot and subsequently edit them via the BPI configuration editor. When such files carry executable extensions and are served by the web application, arbitrary code may be executed in the context of the web application user. Successful exploitation results in arbitrary command execution with the privileges of the Nagios XI web application user and can be leveraged to gain further control of the underlying host operating system.
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 XI versions prior to 2024R1.2 contain a privilege escalation vulnerability related to NagVis configuration handling (nagvis.conf). An authenticated user could manipulate NagVis configuration data or leverage insufficiently validated configuration settings to obtain elevated privileges on the Nagios XI system.
Nagios XI versions prior to 2024R2 contain an improperly owned script, process_perfdata.pl, which is executed periodically as the nagios user but owned by www-data. Because the file was writable by www-data, an attacker with web server privileges could modify its contents, leading to arbitrary code execution as the nagios user when the script is next run. This improper ownership and permission configuration enables local privilege escalation.
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 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 2024R1.2 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 2024R1.1.4 contain a local file inclusion (LFI) vulnerability via its NagVis integration. An authenticated user can supply crafted path values that cause the server to include local files, potentially exposing sensitive information from the underlying host.
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 2024R1.1.2 may (confirmed in 2024R1.1 and 2024R1.1.1) disclose sensitive user account information (including API keys and hashed passwords) to authenticated users who should not have access to that data. Exposure of API keys or password hashes could lead to account compromise, abuse of API privileges, or offline cracking attempts.
