Summary
Nagios XI < 2024R1.3.2 contains a remote code execution vulnerability by chaining two flaws: an arbitrary file upload and a path traversal in the Core Config Snapshots interface. The issue arises from insufficient validation of file paths and extensions during MIB upload and snapshot rename operations. Exploitation results in the placement of attacker-controlled PHP files in a web-accessible directory, executed as the www-data user.
Risk Assessment
The vulnerability allows attackers to achieve remote code execution on the Nagios XI server, potentially leading to full compromise of the monitoring system and further spread within the organization's infrastructure.
Recommendation
Update Nagios XI to version 2024R1.3.2 or later. Until then, restrict access to the Core Config Snapshots interface and monitor for unusual PHP files in web directories.
Other vulnerabilities in Nagios XI
See all- CVE-2025-34284High
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.
- CVE-2024-14005High
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.
- CVE-2024-14003Critical
Nagios XI versions prior to 2024R1.2 are vulnerable to remote code execution (RCE) through its NRDP 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.
- CVE-2024-13999Critical
Nagios XI versions prior to 2024R1.1.3, under certain circumstances, disclose the server's Active Directory (AD) or LDAP authentication token to an authenticated user. Exposure of the server’s AD/LDAP token could allow domain-wide authentication misuse, escalation of privileges, or further compromise of network-integrated systems.
- CVE-2024-13996Critical
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.
- CVE-2024-13994Critical
Nagios XI versions prior to 2024R1.1.2 have a missing authorization control when the 'Allow Insecure Logins' option is enabled. Under this configuration, any user can create valid login credentials for other users without proper authorization.
- CVE-2023-40931Medium
A SQL injection vulnerability in Nagios XI versions 5.11.0 through 5.11.1 allows authenticated attackers to execute arbitrary SQL commands via the ID parameter in a POST request to /nagiosxi/admin/banner_message-ajaxhelper.php.
- CVE-2021-25299Medium
Nagios XI version xi-5.7.5 is affected by cross-site scripting (XSS) in /usr/local/nagiosxi/html/admin/sshterm.php due to improper input sanitization. A crafted URL can steal admin session cookies or be chained with other bugs for one-click RCE.
- CVE-2021-25298HighActively exploited
Nagios XI version xi-5.7.5 is affected by OS command injection due to improper sanitization of authenticated user input in the file /usr/local/nagiosxi/html/includes/configwizards/cloud-vm/cloud-vm.inc.php.
- CVE-2021-25297HighActively exploited
A vulnerability in Nagios XI version xi-5.7.5 allows OS command injection. The issue exists in the switch.inc.php file due to improper sanitization of authenticated user input.
