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.

Incomplete blacklist vulnerability in nrpc.c in Nagios Remote Plug-In Executor (NRPE) before 2.14 might allow remote attackers to execute arbitrary shell commands via "$()" shell metacharacters, which are processed by bash.

Multiple stack-based buffer overflows in the get_history function in history.cgi in Nagios Core before 3.4.4, and Icinga 1.6.x before 1.6.2, 1.7.x before 1.7.4, and 1.8.x before 1.8.4, might allow remote attackers to execute arbitrary code via a long (1) host_name variable (host parameter) or (2) svc_description variable.

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 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

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.

MagpieRSS, as used in the front-end component in Nagios Core before 4.2.2 might allow remote attackers to read or write to arbitrary files by spoofing a crafted response from the Nagios RSS feed server. NOTE: this vulnerability exists because of an incomplete fix for CVE-2008-4796.

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

The Fedora Nagios package uses "nagiosadmin" as the default password for the "nagiosadmin" administrator account, which makes it easier for remote attackers to obtain access by leveraging knowledge of the credentials.

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

Incomplete blacklist vulnerability in nrpe.c in Nagios Remote Plugin Executor (NRPE) 2.15 and earlier allows remote attackers to execute arbitrary commands via a newline character in the -a option to libexec/check_nrpe. NOTE: this issue is disputed by multiple parties. It has been reported that the vendor allows newlines as "expected behavior." Also, this issue can only occur when the administrator enables the "dont_blame_nrpe" option in nrpe.conf despite the "HIGH security risk" warning within the comments

SQL injection vulnerability in Nagios Network Analyzer before 2.4.3 via the o[col] parameter to api/checks/read/.

statuswml.cgi in Nagios before 3.1.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) ping or (2) Traceroute parameters.

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

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.

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

Nagios XI before 5.8.5 incorrectly allows manage_services.sh wildcards.

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.

The _httpsrequest function in Snoopy allows remote attackers to execute arbitrary commands. NOTE: this issue exists dues to an incomplete fix for CVE-2008-4796.

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 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 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.
