SynopsisThe remote web server is hosting a web application that is vulnerable to multiple attack vectors.
DescriptionThe remote web server hosts Moodle, an open-source course management system. Versions of Moodle 3.1.x prior to 3.1.3 are affected by multiple vulnerabilities :
- A flaw exists when debugging is enabled that is triggered as error exceptions from web services may return too much information. This may allow a remote attacker to potentially disclose private data.
- A flaw exists in the question engine that may allow an authenticated remote attacker to download files embedded in questions from the system by guessing the URL of the file downloading it using the identifier of a question they are authorized to access.
- A flaw exists that is due to the program failing to properly perform capability checks on users who have site-wide permissions which were revoked within a specific course. This may allow an authenticated remote attacker to disclose course note information.
SolutionUpgrade to Moodle version 3.1.3 or later.
