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.

Command Injection in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation or Code Execution as root via vectors related to corrupt component installation in cmdsubsys.php.

Command Injection in Nagios Fusion 4.1.8 and earlier allows Privilege Escalation from apache to root in cmdsubsys.php.

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.

Nagios Log Server before 2024R1.3.2 allows authenticated users to retrieve cleartext administrative API keys via a /nagioslogserver/index.php/api/system/getusers call. This is GL:NLS#475.

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.

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority as it is a duplicate of CVE-2025-60425.

Nagios Log Server versions prior to 2024R2.0.3 contain an execution with unnecessary privileges vulnerability as it runs its embedded Logstash process as the root user. If an attacker is able to compromise the Logstash process - for example by exploiting an insecure plugin, pipeline configuration injection, or a vulnerability in input parsing - the attacker could execute code with root privileges, resulting in full system compromise. The Logstash service has been altered to run as the lower-privileged 'nagios' user to reduce this risk associated with a network-facing service that can accept untrusted input or load third-party components.

Nagios Log Server versions prior to 2024R1.3.1 contain a code injection vulnerability where malformed dashboard ID values are not properly validated before being forwarded to an internal API. An attacker able to supply crafted dashboard ID values can cause the system to execute attacker-controlled data, leading to arbitrary code execution in the context of the Log Server process.

Nagios XI versions prior to 2024R1.1.3, under certain circumstances, disclose the server's Active Directory (AD) or LDAP authentication token to an authenticated user. Exposure of the server’s AD/LDAP token could allow domain-wide authentication misuse, escalation of privileges, or further compromise of network-integrated systems.

Nagios Log Server versions prior to 2024R2.0.2 contain a vulnerability in the cluster manager component when requesting sensitive credentials from peer nodes over an unencrypted channel even when SSL/TLS is enabled in the product configuration. As a result, an attacker positioned on the network path can intercept credentials in transit. Captured credentials could allow the attacker to authenticate as a cluster node or service account, enabling further unauthorized access, lateral movement, or system compromise.

Nagios XI versions prior to 2024R1.1.2 contain a missing authorization control when the 'Allow Insecure Logins' option is enabled. Under this configuration, any user can create valid login credentials for other users without proper authorization. This can lead to unauthorized account creation, privilege escalation, or full compromise of the Nagios XI web interface depending on the target account.

Nagios XI versions prior to 2012R1.3 contain a SQL injection vulnerability in the legacy Core Configuration Manager (CCM) interface. Authenticated users could manipulate SQL queries by supplying crafted input to specific CCM parameters, potentially allowing access to configuration data stored in the application database. Successful exploitation could disclose or modify notification data and, in some cases, impact the application database more broadly.

Nagios XI versions prior to 2024R1.2 are vulnerable to remote code execution (RCE) through its NRDP (Nagios Remote Data Processor) server plugins. Insufficient validation of inbound NRDP request parameters allows crafted input to reach command execution paths, enabling attackers to execute arbitrary commands on the underlying host in the context of the web/Nagios service.

Nagios XI versions prior to 2024R1.1.3 did not invalidate all other active sessions for a user when that user's password was changed. As a result, any pre-existing sessions (including those potentially controlled by an attacker) remained valid after a credential update. This insufficient session expiration could allow continued unauthorized access to user data and actions even after a password change.

Nagios XI before version 5.8.5 is vulnerable to SQL injection vulnerability in Bulk Modifications Tool due to improper input sanitisation.

Command Injection in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to nagios.

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 IM (component of Nagios XI) before 2.2.7 allows attackers to execute arbitrary SQL commands.

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.

Authorization bypass in Nagios IM (component of Nagios XI) before 2.2.7 allows closing incidents in IM via the API.

It was found that default configuration for nagios on Fedora is administrative account with user "nagiosadmin" with fixed password "nagiosadmin" and no IP based access restriction. This information is missing in packaged README file.

CVE-2008-4796 describes a command execution flaw in the Snoopy library. A similar fix exists for headers:

http://snoopy.cvs.sourceforge.net/viewvc/snoopy/Snoopy/Snoopy.class.php?view=log#rev1.27

The header fix has been assigned CVE-2008-7313 (as an incomplete fix for CVE-2008-4796).

It was later reported that the CVE-2008-4796 fix was incomplete and command execution was still possible:

http://mstrokin.com/sec/feed2js-magpierss-0day-vulnerability-not-really-it-is-actually-cve-2005-3330-cve-2008-4796/

And fixed with the following:

http://snoopy.cvs.sourceforge.net/viewvc/snoopy/Snoopy/Snoopy.class.php?view=log#rev1.28

This has been assigned CVE-2014-5008 (as an incomplete fix for CVE-2008-4796).

However, the CVE-2014-5008 fix was also incomplete:

https://github.com/cogdog/feed2js/pull/12#issuecomment-48283706

This was fixed with the following:

http://snoopy.cvs.sourceforge.net/viewvc/snoopy/Snoopy/Snoopy.class.php?view=log#rev1.29

And assigned CVE-2014-5009 (as an incomplete fix for CVE-2014-5008).

Snoopy allows remote attackers to execute arbitrary commands. NOTE: this vulnerability exists due to an incomplete fix for CVE-2014-5008.

MagpieRSS, a component for handling RSS news feeds in Nagios Core control panel / front-end, was found vulnerable to command injection due to insufficient neutralization of special elements in function httpsrequest().

The vulnerability could potentially enable remote unauthenticated attackers who managed to impersonate the feed server (via DNS poisoning, domain hijacking, ARP spoofing etc.), to provide a malicious response that injects parameters to curl command used by the affected RSS client class and effectively read/write arbitrary files on the vulnerable Nagios server. This could lead to Remote Code Execution in the context of www-data/nagios user on default Nagios installs that follow the official setup guidelines.

This issue is due to incomplete fix of CVE-2008-4796.
