Moodle 3.1.x < 3.1.5 Multiple Vulnerabilities
Critical Nessus Network Monitor Plugin ID 700010
Synopsis
The remote web server is hosting a web application that is vulnerable to multiple attack vectors.
Description
The remote web server hosts Moodle, an open-source course management system. Versions of Moodle 3.1.x prior to 3.1.5 are affected by multiple unspecified flaws that may allow an attacker to have an unspecified impact. No further details have been provided.
- A flaw exists that allows a Cross-Site Scripting (XSS) attack. This flaw exists because the program does not validate input when handling files attached for evidence for prior learning before returning it to users. This may allow an authenticated remote attacker to create a specially crafted request that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
Solution
Upgrade to Moodle version 3.1.5 or later.
