CVE-2021-25299 1 Nagios 1 Nagios Xi 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
Nagios XI version xi-5.7.5 is affected by cross-site scripting (XSS). The vulnerability exists in the file /usr/local/nagiosxi/html/admin/sshterm.php due to improper sanitization of user-controlled input. A maliciously crafted URL, when clicked by an admin user, can be used to steal his/her session cookies or it can be chained with the previous bugs to get one-click remote command execution (RCE) on the Nagios XI server.
CVE-2021-25298 1 Nagios 1 Nagios Xi 2026-06-17 9.0 HIGH 8.8 HIGH
Nagios XI version xi-5.7.5 is affected by OS command injection. The vulnerability exists in the file /usr/local/nagiosxi/html/includes/configwizards/cloud-vm/cloud-vm.inc.php due to improper sanitization of authenticated user-controlled input by a single HTTP request, which can lead to OS command injection on the Nagios XI server.
CVE-2021-25297 1 Nagios 1 Nagios Xi 2026-06-17 9.0 HIGH 8.8 HIGH
Nagios XI version xi-5.7.5 is affected by OS command injection. The vulnerability exists in the file /usr/local/nagiosxi/html/includes/configwizards/switch/switch.inc.php due to improper sanitization of authenticated user-controlled input by a single HTTP request, which can lead to OS command injection on the Nagios XI server.
CVE-2021-25296 1 Nagios 1 Nagios Xi 2026-06-17 9.0 HIGH 8.8 HIGH
Nagios XI version xi-5.7.5 is affected by OS command injection. The vulnerability exists in the file /usr/local/nagiosxi/html/includes/configwizards/windowswmi/windowswmi.inc.php due to improper sanitization of authenticated user-controlled input by a single HTTP request, which can lead to OS command injection on the Nagios XI server.
CVE-2020-6586 1 Nagios 1 Nagios 2026-06-17 3.5 LOW 5.4 MEDIUM
Nagios Log Server 2.1.3 allows XSS by visiting /profile and entering a crafted name field that is mishandled on the /admin/users page. Any malicious user with limited access can store an XSS payload in his Name. When any admin views this, the XSS is triggered.
CVE-2020-6585 1 Nagios 1 Nagios 2026-06-17 6.8 MEDIUM 8.8 HIGH
Nagios Log Server 2.1.3 has CSRF.
CVE-2020-6584 1 Nagios 1 Nagios 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
Nagios Log Server 2.1.3 has Incorrect Access Control.
CVE-2020-6582 2 Fedoraproject, Nagios 2 Fedora, Remote Plug In Executor 2026-06-17 5.0 MEDIUM 7.5 HIGH
Nagios NRPE 3.2.1 has a Heap-Based Buffer Overflow, as demonstrated by interpretation of a small negative number as a large positive number during a bzero call.
CVE-2020-6581 2 Fedoraproject, Nagios 2 Fedora, Remote Plug In Executor 2026-06-17 3.7 LOW 7.3 HIGH
Nagios NRPE 3.2.1 has Insufficient Filtering because, for example, nasty_metachars interprets \n as the character \ and the character n (not as the \n newline sequence). This can cause command injection.
CVE-2020-5796 1 Nagios 1 Nagios Xi 2026-06-17 7.2 HIGH 7.8 HIGH
Improper preservation of permissions in Nagios XI 5.7.4 allows a local, low-privileged, authenticated user to weaken the permissions of files, resulting in low-privileged users being able to write to and execute arbitrary PHP code with root privileges.
CVE-2020-5792 1 Nagios 1 Nagios Xi 2026-06-17 6.5 MEDIUM 7.2 HIGH
Improper neutralization of argument delimiters in a command in Nagios XI 5.7.3 allows a remote, authenticated admin user to write to arbitrary files and ultimately execute code with the privileges of the apache user.
CVE-2020-5791 1 Nagios 1 Nagios Xi 2026-06-17 9.0 HIGH 7.2 HIGH
Improper neutralization of special elements used in an OS command in Nagios XI 5.7.3 allows a remote, authenticated admin user to execute operating system commands with the privileges of the apache user.
CVE-2020-5790 1 Nagios 1 Nagios Xi 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
Cross-site request forgery in Nagios XI 5.7.3 allows a remote attacker to perform sensitive application actions by tricking legitimate users into clicking a crafted link.
CVE-2020-36869 1 Nagios 1 Nagios Xi 2026-06-17 N/A 7.2 HIGH
Nagios XI versions prior to 5.7.5 contain a SQL injection vulnerability in the SNMP Trap Interface edit 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-2020-36868 1 Nagios 1 Nagios Xi 2026-06-17 N/A 7.8 HIGH
Nagios XI versions prior to 5.7.3 contain a privilege escalation vulnerability in the getprofile.sh helper script. The script performed profile retrieval and initialization routines using insecure file/command handling and insufficient validation of attacker-controlled inputs, and in some deployments executed with elevated privileges. A local attacker with low-level access could exploit these weaknesses to cause the script to execute arbitrary commands or modify privileged files, resulting in privilege escalation.
CVE-2020-36867 1 Nagios 1 Nagios Xi 2026-06-17 N/A 8.8 HIGH
Nagios XI versions prior to 5.7.3 contain a command injection vulnerability in the report PDF download/export functionality. User-supplied values used in the PDF generation pipeline or the wrapper that invokes offline/pdf helper utilities were insufficiently validated or improperly escaped, allowing an authenticated attacker who can trigger PDF exports to inject shell metacharacters or arguments.
CVE-2020-36866 1 Nagios 1 Nagios Xi 2026-06-17 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.
