DoceboLMS 1.2 SQL Injection via lesson.php

DoceboLMS 1.2 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the id, idC, and idU parameters. Attackers can send GET requests to the lesson.php endpoint with malicious SQL payloads to extract sensitive database information.

DoceboLMS 4.0.4 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by views/dummy/show.php and certain other files.

Multiple SQL injection vulnerabilities in the save_connection function in lib/lib.iotask.php in the iotask module in DoceboLMS 4.0.4 and earlier allow remote authenticated users with admin or teacher privileges to execute arbitrary SQL commands via the (1) coursereportuiconfig[name] or (2) coursereportuiconfig[description] parameters to index.php.
