CVE-2020-36865 1 Nagios 1 Nagios Xi 2026-06-17 N/A 5.4 MEDIUM
Nagios XI versions prior to 5.7.2 are vulnerable to cross-site scripting (XSS) via the BPI (Business Process Intelligence) component’s Config Management and Edit Config page. 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-2020-36864 1 Nagios 1 Nagios Xi 2026-06-17 N/A 5.4 MEDIUM
Nagios XI versions prior to 5.7.2 are vulnerable to cross-site scripting (XSS) via the background color settings in Dashboards. 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-2020-36863 1 Nagios 1 Nagios Xi 2026-06-17 N/A 8.8 HIGH
Nagios XI versions prior to 5.7.2 allow PHP files to be uploaded to the Audio Import directory and executed from that location. The upload handler did not properly restrict file types or enforce storage outside of the webroot, and the web server permitted execution within the upload directory. An authenticated attacker with access to the audio import feature could upload a crafted PHP file and then request it to achieve remote code execution with the privileges of the application service.
CVE-2020-36862 1 Nagios 1 Nagios Xi 2026-06-17 N/A 6.1 MEDIUM
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 when the exported content is viewed and to disclose sensitive information reachable from the export server via SSRF.
CVE-2020-36861 1 Nagios 1 Nagios Xi 2026-06-17 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.
CVE-2020-36860 1 Nagios 1 Nagios Xi 2026-06-17 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-2020-36859 1 Nagios 1 Nagios Xi 2026-06-17 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-2020-36858 1 Nagios 1 Log Server 2026-06-17 N/A 5.4 MEDIUM
Nagios Log Server versions prior to 2.1.6 contain cross-site scripting (XSS) vulnerabilities via the web interface on the Create User, Edit User, and Manage Host Lists 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-2020-36857 1 Nagios 1 Nagios Xi 2026-06-17 N/A 7.2 HIGH
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.
CVE-2020-36856 1 Nagios 1 Nagios Xi 2026-06-17 N/A 8.8 HIGH
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. Successful exploitation enables arbitrary command execution with the privileges of the Nagios XI web application user and may be leveraged to execute commands on the underlying XI host, modify system configuration, or fully compromise the host.
CVE-2020-35578 1 Nagios 1 Nagios Xi 2026-06-17 9.0 HIGH 7.2 HIGH
An issue was discovered in the Manage Plugins page in Nagios XI before 5.8.0. Because the line-ending conversion feature is mishandled during a plugin upload, a remote, authenticated admin user can execute operating-system commands.
CVE-2020-35269 1 Nagios 1 Nagios Core 2026-06-17 6.8 MEDIUM 8.8 HIGH
Nagios Core application version 4.2.4 is vulnerable to Site-Wide Cross-Site Request Forgery (CSRF) in many functions, like adding – deleting for hosts or servers.
CVE-2020-28911 1 Nagios 1 Fusion 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
Incorrect Access Control in Nagios Fusion 4.1.8 and earlier allows low-privileged authenticated users to extract passwords used to manage fused servers via the test_server command in ajaxhelper.php.
CVE-2020-28910 1 Nagios 1 Nagios Xi 2026-06-17 10.0 HIGH 9.8 CRITICAL
Creation of a Temporary Directory with Insecure Permissions in Nagios XI 5.7.5 and earlier allows for Privilege Escalation via creation of symlinks, which are mishandled in getprofile.sh.
CVE-2020-28909 1 Nagios 1 Fusion 2026-06-17 9.0 HIGH 8.8 HIGH
Incorrect File Permissions in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to root via modification of scripts. Low-privileges users are able to modify files that can be executed by sudo.
CVE-2020-28908 1 Nagios 1 Fusion 2026-06-17 7.5 HIGH 9.8 CRITICAL
Command Injection in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to nagios.
CVE-2020-28907 1 Nagios 1 Fusion 2026-06-17 10.0 HIGH 9.8 CRITICAL
Incorrect SSL certificate validation in Nagios Fusion 4.1.8 and earlier allows for Escalation of Privileges or Code Execution as root via vectors related to download of an untrusted update package in upgrade_to_latest.sh.
CVE-2020-28906 1 Nagios 2 Fusion, Nagios Xi 2026-06-17 9.0 HIGH 8.8 HIGH
Incorrect File Permissions in Nagios XI 5.7.5 and earlier and Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to root. Low-privileged users are able to modify files that are included (aka sourced) by scripts executed by root.
CVE-2020-28905 1 Nagios 1 Fusion 2026-06-17 6.5 MEDIUM 8.8 HIGH
Improper Input Validation in Nagios Fusion 4.1.8 and earlier allows an authenticated attacker to execute remote code via table pagination.
CVE-2020-28904 1 Nagios 1 Fusion 2026-06-17 7.5 HIGH 9.8 CRITICAL
Execution with Unnecessary Privileges in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation as nagios via installation of a malicious component containing PHP code.
