{"id":"CVE-2020-14871","kind":"vulnerability","aliases":["CVE-2020-14871"],"related":[],"title":"Oracle Solaris and Zettabyte File System (ZFS): Oracle Solaris and Zettabyte File System (ZFS) Unspecified Vulnerability","description":"Vulnerability in the Oracle Solaris product of Oracle Systems (component: Pluggable authentication module). Supported versions that are affected are 10 and 11. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Solaris. While the vulnerability is in Oracle Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Oracle Solaris. Note: This CVE is not exploitable for Solaris 11.1 and later releases, and ZFSSA 8.7 and later releases, thus the CVSS Base Score is 0.0. CVSS 3.1 Base Score 10.0 (Confidentiality, Integrity and Availability impacts).
