An issue was found in Nagios XI before 5.7.3. There is a privilege escalation vulnerability in backend scripts that ran as root where some included files were editable by nagios user. This issue was fixed in version 5.7.3.

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 upgradetolatest.sh.

SQL Injection vulnerability in Nagios XI 2024R1.01 allows a remote attacker to execute arbitrary code via a crafted payload to the monitoringwizard.php component.

An issue in Nagios XI 2024R1.01 allows a remote attacker to escalate privileges via a crafted script to the /usr/local/nagios/bin/npcd component.

An Insufficient Access Control vulnerability (leading to credential disclosure) in coreconfigsnapshot.php (aka configuration snapshot page) in Nagios XI before 5.5.4 allows remote attackers to gain access to configuration files containing confidential credentials.

SQL injection vulnerability in Nagios XI before 5.5.11 allows attackers to execute arbitrary SQL commands via the API when using fusekeys and malicious user id.

Nagios XI before 5.8.5 incorrectly allows backupxi.sh wildcards.

Nagios XI before 5.8.5 incorrectly allows manageservices.sh wildcards.

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

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

DISPUTED Nagios XI 5.6.1 allows SQL injection via the username parameter to login.php?forgotpass (aka the reset password form). NOTE: The vendor disputes this issues as not being a vulnerability because the issue does not seem to be a legitimate SQL Injection. The POC does not show any valid injection that can be done with the variable provided, and while the username value being passed does get used in a SQL query, it is passed through SQL escaping functions when creating the call. The vendor tried re-creating the issue with no luck.

Snoopy 1.0 in Nagios XI 5.5.6 allows remote unauthenticated attackers to execute arbitrary commands via a crafted HTTP request.

Nagios XI v5.8.6 was discovered to contain a SQL injection vulnerability via the mibname parameter at the Manage MIBs page.

Nagios XI before version 5.11.3 was discovered to contain a remote code execution (RCE) vulnerability via the component commandtest.php.

Nagios XI before version 5.11.3 was discovered to contain a SQL injection vulnerability via the bulk modification tool.

Nagios XI versions prior to 2026R1 contain a remote code execution vulnerability in the Core Config Manager (CCM) Run Check command. Insufficient validation/escaping of parameters used to build backend command lines allows an authenticated administrator to inject shell metacharacters that are executed on the server. Successful exploitation results in arbitrary command execution with the privileges of the Nagios XI web application user and can be leveraged to gain control of the underlying host operating system.

Nagios XI versions prior to 2024R1 contain a missing access control vulnerability via the Web SSH Terminal. A remote, low-privileged attacker could access or interact with the terminal interface without sufficient authorization, potentially allowing unauthorized command execution or disclosure of sensitive information.

Improper input validation in the Auto-Discovery component of Nagios XI before 5.7.5 allows an authenticated attacker to execute remote code.

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.

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.

In Nagios XI 5.6.9, an authenticated user is able to execute arbitrary OS commands via shell metacharacters in the id parameter to schedulereport.php, in the context of the web-server user account.

An issue was discovered in Nagios XI 5.8.5. In the Manage Dashlets section of the Admin panel, an administrator can upload ZIP files. A command injection (within the name of the first file in the archive) allows an attacker to execute system commands.

An issue with the Autodiscover component in Nagios XI 2024R1.01 allows a remote attacker to escalate privileges via a crafted Dashlet.

Nagios XI < 2024R1.3.2 contains a remote code execution vulnerability by chaining two flaws: an arbitrary file upload and a path traversal in the Core Config Snapshots interface. The issue arises from insufficient validation of file paths and extensions during MIB upload and snapshot rename operations. Exploitation results in the placement of attacker-controlled PHP files in a web-accessible directory, executed as the www-data user.

Nagios XI < 2026R1 is vulnerable to an authenticated command injection vulnerability within the MongoDB Database, MySQL Query, MySQL Server, Postgres Server, and Postgres Query wizards. It is possible to inject shell characters into arguments provided to the service and execute arbitrary system commands on the underlying host as the nagios user.

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.

Command injection in Nagios XI before 5.5.11 allows an authenticated users to execute arbitrary remote commands via a new autodiscovery job.

Nagios XI 5.7.2 is affected by a remote code execution (RCE) vulnerability. An authenticated user can inject additional commands into normal webapp query.

In Nagios XI before 5.7.3, ajaxhelper.php allows remote authenticated attackers to execute arbitrary commands via cmdsubsys.
