CVE-2020-2927: Vulnerability in the Oracle Solaris product of Oracle Systems (component: Common Desktop Environment).

Vulnerability in the Oracle Solaris product of Oracle Systems (component: Common Desktop Environment). Supported versions that are affected are 10 and 11. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Solaris executes 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. CVSS 3.0 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H).

Security readout for executives and security teams

Plain-English summary

CVE-2020-2927 is a high-severity Oracle Solaris flaw in Common Desktop Environment affecting Solaris 10 and 11. A logged-in low-privileged attacker could, despite high attack complexity, take over the Solaris system. Business concern is highest where legacy Solaris hosts still allow local user access.

Executive priority

Treat as a legacy-platform takeover risk. Prioritize systems supporting business-critical workloads or broad local-user access, but weigh urgency against the high attack complexity and lack of confirmed exploitation in the provided sources.

Technical view

The CVSS 3.0 vector is AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H, score 7.8. The vulnerability is local, requires low privileges, needs no user interaction, has changed scope, and can fully impact confidentiality, integrity, and availability. Oracle identifies the affected component as Common Desktop Environment.

Likely exposure

Exposure is likely limited to Oracle Solaris 10 or 11 environments, especially systems where low-privileged users can log on. The source bundle does not identify affected packages, configurations, or non-Solaris products.

Exploitation context

The sources describe exploitation as difficult and local. No source in the bundle reports active exploitation, and the CVE is not listed as KEV. Treat exploit status as unconfirmed unless Oracle or CISA later states otherwise.

Researcher notes

The record lacks CWE, root-cause detail, package names, and exact fixed versions. Validation should focus on affected Solaris versions, CDE exposure, and Oracle CPU status rather than exploit reproduction. Do not assume impact to named additional products without vendor evidence.

Mitigation direction

  • Review Oracle's April 2020 Critical Patch Update guidance for Solaris.
  • Apply the relevant Oracle Solaris security updates where supported.
  • Restrict local logon access to trusted users only.
  • Prioritize replacement or isolation for unsupported Solaris deployments.
  • Monitor Oracle advisories for any later workaround or patch clarification.

Validation and detection

  • Inventory all Oracle Solaris 10 and 11 systems.
  • Confirm whether Common Desktop Environment is present or used.
  • Check each host's Oracle CPU patch level.
  • Review local account access and privilege assignments.
  • Document compensating controls for unpatchable systems.
