CVE-2020-2805

22
FAUCET Score

CVE-2020-2805 is a high-severity vulnerability in Oracle Java SE and Java SE Embedded (component: Libraries) affecting versions 7u251, 8u241, 11.0.6, and 14. This vulnerability allows an unauthenticated attacker to compromise affected Java deployments, particularly client-side sandboxed applications that load untrusted code. With a CVSS 3.0 Base Score of 8.3, successful exploitation requires human interaction and network access, leading to potential complete takeover (Confidentiality, Integrity, and Availability impacts). While difficult to exploit, attacks can significantly impact additional products beyond Java itself. Currently, there is no known public exploit code (Metasploit, Nuclei, ExploitDB) and it is not listed on the CISA KEV catalog. Community discussion and media coverage for this CVE are minimal, indicating low public awareness or active exploitation.
