CVE-2021-35650: Vulnerability in the Oracle Secure Global Desktop product of Oracle Virtualization (component: Client).

Vulnerability in the Oracle Secure Global Desktop product of Oracle Virtualization (component: Client). The supported version that is affected is 5.6. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise Oracle Secure Global Desktop. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Secure Global Desktop accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Secure Global Desktop. CVSS 3.1 Base Score 4.6 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L).

Security readout for executives and security teams

Plain-English summary

CVE-2021-35650 affects Oracle Secure Global Desktop 5.6. A low-privileged network attacker could, with another user’s interaction, read some accessible data or partially disrupt the service. The published severity is medium, with limited confidentiality and availability impact and no stated integrity impact.

Executive priority

Treat as a medium-priority remediation item for environments using Oracle Secure Global Desktop 5.6. Prioritize higher if the service is broadly reachable by internal users or supports sensitive remote access workflows.

Technical view

The CVE describes an easily exploitable Client component issue in Oracle Secure Global Desktop 5.6. Attack prerequisites are network access over multiple protocols, low privileges, and required user interaction by someone other than the attacker. CVSS 3.1 is 4.6: AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L.

Likely exposure

Exposure is limited to organizations running Oracle Secure Global Desktop 5.6. The source bundle does not identify other affected versions, products, CPEs, or deployment-specific prerequisites beyond network access, low privileges, and user interaction.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. The vulnerability is described as easy to exploit, but successful exploitation requires low privileges and human interaction, reducing immediacy compared with unauthenticated or no-click issues.

Researcher notes

Evidence is sparse: no CWE, exploit details, CPE list, or explicit active exploitation are provided. Analysis should stay close to the CVSS vector and Oracle advisory. Avoid assuming affected versions beyond 5.6 or specific patch mechanics not present in the sources.

Mitigation direction

  • Review Oracle’s October 2021 Critical Patch Update guidance for this CVE.
  • Apply applicable Oracle Secure Global Desktop 5.6 vendor updates or mitigations.
  • Limit network access to Secure Global Desktop to trusted users and segments.
  • Reduce unnecessary low-privileged accounts with access to the service.
  • Monitor for unusual data access or partial service disruption symptoms.

Validation and detection

  • Inventory Oracle Secure Global Desktop deployments and confirm any version 5.6 systems.
  • Check whether Oracle October 2021 CPU guidance has been applied.
  • Verify network paths that allow low-privileged users to reach the service.
  • Confirm user-interaction surfaces tied to the Client component are understood.
  • Review logs for unexplained read activity or partial denial-of-service events.
