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.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
