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.

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 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().

An issue was discovered in LibreNMS through 1.47. A number of scripts import the Authentication libraries, but do not enforce an actual authentication check. Several of these scripts disclose information or expose functions that are of a sensitive nature and are not expected to be publicly accessible.

An issue was discovered in LibreNMS through 1.47. Information disclosure can occur: an attacker can fingerprint the exact code version installed and disclose local file paths.

An issue was discovered in LibreNMS through 1.47. Several of the scripts perform dynamic script inclusion via the include() function on user supplied input without sanitizing the values by calling basename() or a similar function. An attacker can leverage this to execute PHP code from the included file. Exploitation of these scripts is made difficult by additional text being appended (typically .inc.php), which means an attacker would need to be able to control both a filename and its content on the server. However, exploitation can be achieved as demonstrated by the csv.php?report=../ substring.
