CVE-2020-14321

40
FAUCET Score

CVE-2020-14321 describes a critical privilege escalation vulnerability in Moodle versions prior to 3.9.1, 3.8.4, 3.7.7, and 3.5.13, where teachers could illicitly assign themselves the manager role within their courses. With a CVSS score of 8.8 (High), this vulnerability is easily exploitable over the network with low privileges and no user interaction, leading to complete compromise of confidentiality, integrity, and availability within the affected course. While not currently on CISA's KEV catalog or showing active exploitation in the wild, a Metasploit module exists, demonstrating a clear path to remote code execution, and its high EPSS and FAUCET Risk Scores indicate significant exploitability potential.
