CVE-2025-34323 1 Nagios 1 Log Server 2025-11-26 N/A 7.8 HIGH
Nagios Log Server versions prior to 2026R1.0.1 are vulnerable to local privilege escalation due to a combination of sudo misconfiguration and group-writable application directories. The 'www-data' user is a member of the 'nagios' group, which has write access to '/usr/local/nagioslogserver/scripts', while several scripts in this directory are owned by root and may be executed via sudo without a password. A local attacker running as 'www-data' can move one of these root-owned scripts to a backup name and create a replacement script with attacker-controlled content at the original path, then invoke it with sudo. This allows arbitrary commands to be executed with root privileges, providing full compromise of the underlying operating system.
CVE-2025-34322 1 Nagios 1 Log Server 2025-11-26 N/A 7.2 HIGH
Nagios Log Server versions prior to 2026R1.0.1 contain an authenticated command injection vulnerability in the experimental 'Natural Language Queries' feature. When this feature is configured, certain user-controlled settings—including model selection and connection parameters—are read from the global configuration and concatenated into a shell command that is executed via shell_exec() without proper input handling or command-line argument sanitation. An authenticated user with access to the 'Global Settings' page can supply crafted values in these fields to inject additional shell commands, resulting in arbitrary command execution as the 'www-data' user and compromise of the Log Server host.
CVE-2023-7319 1 Nagios 1 Network Analyzer 2025-11-07 N/A 5.4 MEDIUM
Nagios Network Analyzer versions prior to 2024R1 are vulnerable to cross-site scripting (XSS) via the Percentile Calculator menu. 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.
CVE-2021-47698 1 Nagios 1 Nagios Xi 2025-11-07 N/A 5.4 MEDIUM
Nagios XI versions prior to 5.8.7 using embedded Nagios Core are vulnerable to cross-site scripting (XSS) via the Core UI’s Views URL handling (escape_string()). 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.
CVE-2020-36866 1 Nagios 1 Nagios Xi 2025-11-06 N/A 5.4 MEDIUM
Nagios XI versions prior to 5.7.3 are vulnerable to cross-site scripting (XSS) via the Manage Users page of the Admin 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.
CVE-2017-20209 1 Nagios 1 Fusion 2025-11-06 N/A 6.1 MEDIUM
Nagios Fusion versions prior to 4.0.1 are vulnerable to cross-site scripting (XSS) via the Users and Servers 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.
CVE-2018-25119 1 Nagios 1 Fusion 2025-11-06 N/A 6.1 MEDIUM
Nagios Fusion versions prior to 4.1.5 are vulnerable to cross-site scripting (XSS) via the "fusionwindow" parameter. 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.
CVE-2023-53689 1 Nagios 1 Fusion 2025-11-06 N/A 4.8 MEDIUM
Nagios Fusion versions prior to 4.2.0 contain a reflected cross-site scripting (XSS) vulnerability in the license key configuration flow that can result in execution of attacker-controlled script in the browser of a user who follows a crafted URL. While the application server itself is not directly corrupted by the reflected XSS, the resulting browser compromise can lead to credential/session theft and unauthorized administrative actions.
CVE-2020-36859 1 Nagios 1 Nagios Xi 2025-11-06 N/A 8.8 HIGH
The Core Config Manager (CCM) in Nagios XI versions prior to CCM 3.0.7 / Nagios XI 5.7.4 contains multiple SQL injection vulnerabilities in the object edit pages. Unsanitized user-supplied input was incorporated into SQL queries used by configuration object editors, allowing authenticated users to inject SQL fragments. Successful exploitation could lead to unauthorized disclosure or modification of configuration and application data, and in some environments could allow further compromise of the application or backend database.
CVE-2020-36860 1 Nagios 1 Nagios Xi 2025-11-06 N/A 5.4 MEDIUM
The Core Config Manager (CCM) in Nagios XI versions prior to CCM 3.0.7 / Nagios XI 5.7.4 contains multiple cross-site scripting (XSS) vulnerabilities in the object edit 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.
CVE-2020-36861 1 Nagios 1 Nagios Xi 2025-11-06 N/A 5.4 MEDIUM
The Core Config Manager (CCM) in Nagios XI versions prior to CCM 3.0.8 / Nagios XI 5.7.5 contains multiple cross-site scripting (XSS) vulnerabilities in the overlay UI elements and the Notification/Check Period 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.
