CVE-2022-21514: Vulnerability in the Oracle Solaris product of Oracle Systems (component: Remote Administration Daemon).

Vulnerability in the Oracle Solaris product of Oracle Systems (component: Remote Administration Daemon). The supported version that is affected is 11. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Solaris. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Solaris. CVSS 3.1 Base Score 7.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

Security readout for executives and security teams

Plain-English summary

A flaw in Oracle Solaris 11's Remote Administration Daemon can let an unauthenticated network attacker crash or hang the system. The impact described is denial of service only, but it can still disrupt systems that depend on Solaris availability.

Executive priority

Prioritize remediation for Solaris 11 systems that support critical operations or have reachable administration services. The risk is service outage rather than data compromise, but the unauthenticated remote attack path makes exposed systems business-relevant.

Technical view

CVE-2022-21514 affects Oracle Solaris 11 Remote Administration Daemon. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, meaning remote, low-complexity, unauthenticated denial of service with high availability impact and no stated confidentiality or integrity impact.

Likely exposure

Organizations running Oracle Solaris 11 with the Remote Administration Daemon reachable over a network. Exposure is highest where administrative services are accessible from untrusted networks or broad management segments. The bundle does not identify other Solaris versions or products.

Exploitation context

The CVE says exploitation is easy and network-based via multiple protocols. KEV is false, and the provided sources do not report active exploitation or public exploit availability. Treat this as a remotely triggerable availability risk, not a data theft or privilege escalation issue.

Researcher notes

Evidence is limited to the CVE description and Oracle CPU reference. No CWE, exploit narrative, root cause, protocol specifics, or confirmed active exploitation are provided in the bundle. Avoid assuming affected configurations beyond Solaris 11 Remote Administration Daemon.

Mitigation direction

  • Review Oracle's July 2022 CPU and current Solaris guidance for the applicable Solaris 11 fix.
  • Apply the vendor-supported Solaris 11 update after operational testing.
  • Limit network reachability to the Remote Administration Daemon where business operations allow.
  • Prioritize controls on internet-facing and broadly reachable management networks.

Validation and detection

  • Inventory systems running Oracle Solaris 11.
  • Identify whether the Remote Administration Daemon is enabled and network reachable.
  • Compare installed Solaris patch or SRU levels against Oracle's advisory guidance.
  • Check monitoring for repeated crashes, hangs, or unexplained Solaris availability incidents.
