Nagios XI vulnerabilities

Nagios XI versions prior to 5.6.11 contain unauthenticated vulnerabilities in the Highcharts local exporting tool. Crafted export requests could (1) inject script into exported/returned content due to insufficient output encoding (XSS), and (2) cause the server to fetch attacker-specified URLs (SSRF), potentially accessing internal network resources. An unauthenticated remote attacker can leverage these issues to execute script in a user's browser and disclose sensitive information.

Nagios XI versions prior to 5.6.14 contain a post-authentication SQL injection vulnerability in the SNMP Trap Interface page. Exploitation requires an account with administrative privileges to access the affected interface. A user with administrative access could supply crafted input that is not properly sanitized, allowing SQL injection that may lead to unauthorized disclosure or modification of application data or execution of arbitrary SQL commands against the backend database.

Nagios XI versions prior to 5.6.14 contain an authenticated remote command execution vulnerability in the CCM command_test.php script. Insufficient validation of the `address` parameter allows an authenticated user with access to the Core Config Manager to inject shell metacharacters that are incorporated into backend command invocations.

Nagios XI versions prior to 5.5.7 contain a privilege escalation vulnerability in the MRTG graphing component. MRTG-related processes/scripts executed with excessive privileges, allowing a local attacker with limited system access to abuse file/command execution paths or writable resources to gain elevated privileges.

Nagios XI versions prior to 5.4.13 contain a remote code execution vulnerability in the Component Download page. The download/import handler used unsafe command construction with attacker-controlled input and lacked sufficient validation and output encoding, allowing an authenticated user to inject commands or otherwise execute arbitrary code with the privileges of the application service.

Nagios XI versions prior to 5.4.13 are vulnerable to cross-site scripting (XSS) via the Views page of the web interface. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 5.2.4 are vulnerable to cross-site scripting (XSS) via the “My Reports” listing of the web interface. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 5.2.4 are vulnerable to cross-site scripting (XSS) via the Menu System of the web interface. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 5.2.4 are vulnerable to cross-site scripting (XSS) via the Reports interface through values from the startdate and enddate fields. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 5.2.4 contain a SQL injection vulnerability in the notification search functionality. User-supplied search parameters were incorporated into SQL statements without adequate parameterization or sanitation, allowing an authenticated user to manipulate database queries. Successful exploitation could disclose or modify notification data and, in some cases, impact the application database more broadly.

Nagios XI versions prior to 2012R2.6 are vulnerable to cross-site scripting (XSS) via the Tools Menu of the web interface. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 2012R1.6 contain a shell command injection vulnerability in the Auto-Discovery tool. User-controlled input is passed to a shell without adequate sanitation or argument quoting, allowing an authenticated user with access to discovery functionality to execute arbitrary commands with the privileges of the application service.

Nagios XI versions prior to 2012R1.6 contain an authorization flaw in the Auto-Discovery functionality. Users with read-only roles could directly reach Auto-Discovery endpoints and pages that should require elevated permissions, exposing discovery results and allowing unintended access to discovery operations.

Nagios XI versions prior to 2012R1.6 contain a reflected cross-site scripting (XSS) vulnerability in the dashboard dashlet AJAX load functionality. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 2011R1.9 are vulnerable to cross-site scripting (XSS) via the link-handling functions used by status and report pages. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 2011R1.9 are vulnerable to cross-site scripting (XSS) via the Alert Heatmap report and the "My Reports" listing of the web interface. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 2011R1.9 are vulnerable to cross-site scripting (XSS) via the recurring downtime script of the web interface. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 2011R1.9 are vulnerable to cross-site scripting (XSS) via the handling of xiwindow variables used to build permalinks in the web interface. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 2011R1.9 are vulnerable to cross-site scripting (XSS) via the handling of the "backend_url" JavaScript link. Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

Nagios XI versions prior to 2011R1.9 contain privilege escalation vulnerabilities in the scripts that install or update system crontab entries. Due to time-of-check/time-of-use race conditions and missing synchronization or final-path validation, a local low-privileged user could manipulate filesystem state during crontab installation to influence the files or commands executed with elevated privileges, resulting in execution with higher privileges.

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.

A cross-site scripting (XSS) vulnerability exists in Nagios XI 2024R2. The vulnerability allows remote attackers to execute arbitrary JavaScript in the context of a logged-in user's session via a specially crafted URL. The issue resides in a web component responsible for rendering performance-related data.

An issue with the Autodiscover component in Nagios XI 2024R1.01 allows a remote attacker to escalate privileges via a crafted Dashlet.

A SQL injection vulnerability in Nagios XI 5.11.1 and below allows authenticated attackers with privileges to manage host escalations in the Core Configuration Manager to execute arbitrary SQL commands via the host escalation notification settings.

A SQL injection vulnerability in Nagios XI v5.11.1 and below allows authenticated attackers with announcement banner configuration privileges to execute arbitrary SQL commands via the ID parameter sent to the update_banner_message() function.

A Cross-site scripting (XSS) vulnerability in Nagios XI version 5.11.1 and below allows authenticated attackers with access to the custom logo component to inject arbitrary JavaScript or HTML via the alt-text field. This affects all pages containing the navbar including the login page, enabling the attacker to steal plaintext credentials.

A vulnerability in Nagios XI before version 5.8.5 allows local privilege escalation. This is due to the xi-sys.cfg file being imported from the var directory by scripts running with elevated privileges.
