CVE-2018-11765 describes an authentication bypass vulnerability in Apache Hadoop versions 3.0.0-alpha2 to 3.0.0, 2.9.0 to 2.9.2, and 2.8.0 to 2.8.5. When Kerberos is enabled but SPNEGO over HTTP is not, unauthenticated users can access certain servlets, potentially leading to information disclosure. This high-severity vulnerability (CVSS 7.5) has a low attack complexity and requires no user interaction, allowing remote attackers to achieve high confidentiality impact. Despite its severity, there is no known active exploitation, public exploit code, or significant community discussion surrounding this CVE.
