LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. A Self Cross-Site Scripting (Self-XSS) vulnerability in the "Alert Templates" feature allows users to inject arbitrary JavaScript into the alert template's name. This script executes immediately upon submission but does not persist after a page refresh.

LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. A Stored Cross-Site Scripting (XSS) vulnerability in the "Alert Rules" feature allows authenticated users to inject arbitrary JavaScript through the "Title" field. This vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and allowing unauthorized actions. This vulnerability is fixed in 24.9.0.

LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. User with Admin role can create a Device Groups, the application did not properly sanitize the user input in the Device Groups name, when user see the detail of the Device Group, if java script code is inside the name of the Device Groups, its will be trigger. This vulnerability is fixed in 24.9.0.

LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. A Stored Cross-Site Scripting (XSS) vulnerability in the "Alert Transports" feature allows authenticated users to inject arbitrary JavaScript through the "Details" section (which contains multiple fields depending on which transport is selected at that moment). This vulnerability can lead to the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and allowing unauthorized actions. This vulnerability is fixed in 24.9.0.

LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. Versions prior to 24.4.0 are vulnerable to SQL injection. The `order` parameter is obtained from `$request`. After performing a string check, the value is directly incorporated into an SQL statement and concatenated, resulting in a SQL injection vulnerability. An attacker may extract a whole database this way. Version 24.4.0 fixes the issue.

LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. Prior to version 24.4.0, there is improper sanitization on the `Service` template name, which can lead to stored Cross-site Scripting. Version 24.4.0 fixes this vulnerability.

LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. A SQL injection vulnerability in POST /search/search=packages in LibreNMS prior to version 24.4.0 allows a user with global read privileges to execute SQL commands via the package parameter. With this vulnerability, an attacker can exploit a SQL injection time based vulnerability to extract all data from the database, such as administrator credentials. Version 24.4.0 contains a patch for the vulnerability.

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems. In affected versions of LibreNMS when a user accesses their device dashboard, one request is sent to `graph.php` to access graphs generated on the particular Device. This request can be accessed by a low privilege user and they can enumerate devices on librenms with their id or hostname. Leveraging this vulnerability a low privilege user can see all devices registered by admin users. This vulnerability has been addressed in commit `489978a923` which has been included in release version 23.11.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems. In affected versions the login method has no rate limit. An attacker may be able to leverage this vulnerability to gain access to user accounts. This issue has been addressed in version 23.11.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems. Affected versions are subject to a cross site scripting (XSS) vulnerability in the device group popups. This issue has been addressed in commit `faf66035ea` which has been included in release version 23.11.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
