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.

Insufficient Session Expiration in GitHub repository librenms/librenms prior to 22.10.0.

Cross-site Scripting (XSS) - Generic in GitHub repository librenms/librenms prior to 22.10.0.

A user is able to enable their own account if it was disabled by an admin while the user still holds a valid session. Moreover, the username is not properly sanitized in the admin user overview. This enables an XSS attack that enables an attacker with a low privilege user to execute arbitrary JavaScript in the context of an admin's account.

Librenms 21.11.0 is affected by a Cross Site Scripting (XSS) vulnerability in includes/html/forms/poller-groups.inc.php.

Librenms 21.11.0 is affected by a path manipulation vulnerability in includes/html/pages/device/showconfig.inc.php.

Librenms 21.11.0 is affected by a Cross Site Scripting (XSS) vulnerability in includes/html/common/alert-log.inc.php.

LibreNMS through 21.10.2 allows XSS via a widget title.

In LibreNMS < 21.3.0, a stored XSS vulnerability was identified in the API Access page due to insufficient sanitization of the $api->description variable. As a result, arbitrary Javascript code can get executed.

A second-order SQL injection issue in Widgets/TopDevicesController.php (aka the Top Devices dashboard widget) of LibreNMS before 21.1.0 allows remote authenticated attackers to execute arbitrary SQL commands via the sort_order parameter against the /ajax/form/widget-settings endpoint.

An issue was discovered in LibreNMS before 1.65.1. It has insufficient access control for normal users because of "'guard' => 'admin'" instead of "'middleware' => ['can:admin']" in routes/web.php.

In LibreNMS before 1.65.1, an authenticated attacker can achieve SQL Injection via the customoid.inc.php device_id POST parameter to ajax_form.php.

LibreNMS v1.54 has XSS in the Create User, Inventory, Add Device, Notifications, Alert Rule, Create Maintenance, and Alert Template sections of the admin console. This could lead to cookie stealing and other malicious actions. This vulnerability can be exploited with an authenticated account.

An issue was discovered in LibreNMS 1.50.1. A SQL injection flaw was identified in the ajax_rulesuggest.php file where the term parameter is used insecurely in a database query for showing columns of a table, as demonstrated by an ajax_rulesuggest.php?debug=1&term= request.

An issue was discovered in LibreNMS 1.50.1. An authenticated user can perform a directory traversal attack against the /pdf.php file with a partial filename in the report parameter, to cause local file inclusion resulting in code execution.

An issue was discovered in LibreNMS 1.50.1. The scripts that handle graphing options (includes/html/graphs/common.inc.php and includes/html/graphs/graphs.inc.php) do not sufficiently validate or encode several fields of user supplied input. Some parameters are filtered with mysqli_real_escape_string, which is only useful for preventing SQL injection attacks; other parameters are unfiltered. This allows an attacker to inject RRDtool syntax with newline characters via the html/graph.php and html/g ... An issue was discovered in LibreNMS 1.50.1. The scripts that handle graphing options (includes/html/graphs/common.inc.php and includes/html/graphs/graphs.inc.php) do not sufficiently validate or encode several fields of user supplied input. Some parameters are filtered with mysqli_real_escape_string, which is only useful for preventing SQL injection attacks; other parameters are unfiltered. This allows an attacker to inject RRDtool syntax with newline characters via the html/graph.php and html/graph-realtime.php scripts. RRDtool syntax is quite versatile and an attacker could leverage this to perform a number of attacks, including disclosing directory structure and filenames, disclosing file content, denial of service, or writing arbitrary files. NOTE: relative to CVE-2019-10665, this requires authentication and the pathnames differ.

An issue was discovered in LibreNMS through 1.47. It does not parameterize all user supplied input within database queries, resulting in SQL injection. An authenticated attacker can subvert these database queries to extract or manipulate data, as demonstrated by the graph.php sort parameter.

An issue was discovered in LibreNMS through 1.47. Many of the scripts rely on the function mysqli_escape_real_string for filtering data. However, this is particularly ineffective when returning user supplied input in an HTML or a JavaScript context, resulting in unsafe data being injected into these contexts, leading to attacker controlled JavaScript executing in the browser. One example of this is the string parameter in html/pages/inventory.inc.php.

An issue was discovered in LibreNMS through 1.47. There is a command injection vulnerability in html/includes/graphs/device/collectd.inc.php where user supplied parameters are filtered with the mysqli_escape_real_string function. This function is not the appropriate function to sanitize command arguments as it does not escape a number of command line syntax characters such as ` (backtick), allowing an attacker to inject commands into the variable $rrd_cmd, which gets executed via passthru().
