Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: Kernel RPC). For supported versions that are affected see note. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Solaris. While the vulnerability is in Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Solaris. Note: CVE-2017-3623 is assigned for "Ebbisland". Solaris 10 systems which have had any Kernel patch installed after, or updated via patching tools since 2012-01-26 are not impacted. Also, any Solaris 10 system installed with Solaris 10 1/13 (Solaris 10 Update 11) are not vulnerable. Solaris 11 is not impacted by this issue. CVSS 3.0 Base Score 10.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
