CVE-2020-14759: Vulnerability in the Oracle Solaris product of Oracle Systems (component: Kernel).

Vulnerability in the Oracle Solaris product of Oracle Systems (component: Kernel). The supported version that is affected is 11. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Solaris executes to compromise Oracle Solaris. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Solaris accessible data. CVSS 3.1 Base Score 2.5 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

CVE-2020-14759 is a low-severity Oracle Solaris kernel issue affecting Solaris 11. An attacker already able to log on with low privileges could, with difficult conditions and another person’s interaction, make unauthorized limited data changes. The sources do not show confidentiality loss, outage impact, or confirmed active exploitation.

Executive priority

Treat this as routine remediation unless Solaris 11 systems host sensitive data and allow broad local user access. It does not warrant emergency response from the supplied evidence, but should be included in normal Solaris patch governance.

Technical view

The CVSS 3.1 vector is local, high complexity, low privileges required, user interaction required, changed scope, no confidentiality impact, low integrity impact, and no availability impact. Oracle identifies the affected component as the Solaris kernel in Solaris 11.

Likely exposure

Exposure is likely limited to organizations running Oracle Solaris 11 where low-privileged users can log on to the infrastructure hosting Solaris. Systems without local user access are less directly exposed based on the CVSS vector.

Exploitation context

The CVE description says exploitation is difficult, requires local logon, low privileges, and interaction by someone other than the attacker. The source bundle does not cite KEV listing, public exploitation, exploit code, or observed attacks.

Researcher notes

The public record provides limited technical detail: no CWE, no root cause, and no named patch identifier in the bundle. Validation should focus on Solaris 11 presence, local-login exposure, patch posture against Oracle’s October 2020 CPU, and integrity-sensitive workloads.

Mitigation direction

  • Review Oracle Critical Patch Update guidance from October 2020 for Solaris 11.
  • Apply the relevant Oracle Solaris 11 security updates where applicable.
  • Restrict low-privileged interactive logon access to Solaris systems.
  • Prioritize systems with shared user access or sensitive writable data.
  • Monitor Oracle advisories for any later remediation clarification.

Validation and detection

  • Inventory hosts running Oracle Solaris 11.
  • Compare Solaris patch levels against Oracle CPU October 2020 guidance.
  • Confirm which users have local or interactive logon rights.
  • Review logs and integrity controls for unexpected data modifications.
  • Document any exception where vendor guidance cannot be applied.
