An open redirect vulnerability exists in Nagios XI before version 5.8.5 that could lead to spoofing. To exploit the vulnerability, an attacker could send a link that has a specially crafted URL and convince the user to click the link.

Nagios XI Docker Wizard before version 1.1.3 is vulnerable to SSRF due to improper sanitation in table_population.php.

Nagios XI before version 5.8.5 is vulnerable to local privilege escalation because getprofile.sh does not validate the directory name it receives as an argument.

Nagios XI WatchGuard Wizard before version 1.4.8 is vulnerable to remote code execution through Improper neutralisation of special elements used in an OS Command (OS Command injection).

Nagios XI before version 5.8.5 is vulnerable to local privilege escalation because xi-sys.cfg is being imported from the var directory for some scripts with elevated permissions.

Nagios XI 5.7.5 and earlier allows authenticated admins to upload arbitrary files due to improper validation of the rename functionality in custom-includes component, which leads to remote code execution by uploading php files.

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.

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.

Insufficient Verification of Data Authenticity in Nagios Fusion 4.1.8 and earlier and Nagios XI 5.7.5 and earlier allows for Escalation of Privileges or Code Execution as root via vectors related to an untrusted update package to upgrade_to_latest.sh.

Nagios XI below 5.7 is affected by code injection in the /nagiosxi/admin/graphtemplates.php component. To exploit this vulnerability, someone must have an admin user account in Nagios XI's web system.
