A path traversal vulnerability exists in Nagios XI below version 5.8.5 AutoDiscovery component and could lead to post authenticated RCE under security context of the user running Nagios.

Nagios Enterprises NagiosXI <= 5.8.4 contains a Server-Side Request Forgery (SSRF) vulnerability in schedulereport.php. Any authenticated user can create scheduled reports containing PDF screenshots of any view in the NagiosXI application. Due to lack of input sanitisation, the target page can be replaced with an SSRF payload to access internal resources or disclose local system files.

Nagios XI before 5.8.5 incorrectly allows manage_services.sh wildcards.

Nagios XI before 5.8.5 has Incorrect Permission Assignment for repairmysql.sh.

Nagios XI before 5.8.5 incorrectly allows backup_xi.sh wildcards.

Nagios XI before 5.8.5 has Incorrect Permission Assignment for migrate.php.

The general user interface in Nagios XI versions prior to 5.8.4 is vulnerable to authenticated reflected cross-site scripting. An authenticated victim, who accesses a specially crafted malicious URL, would unknowingly execute the attached payload.

The Bulk Modifications functionality in Nagios XI versions prior to 5.8.5 is vulnerable to SQL injection. Exploitation requires the malicious actor to be authenticated to the vulnerable system, but once authenticated they would be able to execute arbitrary sql queries.

The Favorites component before 1.0.2 for Nagios XI 5.8.0 is vulnerable to Insecure Direct Object Reference: it is possible to create favorites for any other user account.

The Favorites component before 1.0.2 for Nagios XI 5.8.0 is vulnerable to XSS.

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.

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.

Nagios Log Server 2.1.3 has CSRF.

Nagios Log Server 2.1.3 has Incorrect Access Control.

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.

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.

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.

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.

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.
