CVE-2018-2822 — Vulnerability in the Solaris Cluster component of Oracle Sun Systems Products Suite (subcomponent: Cluster Geo)

Medium CVSS 6.6

Vulnerability in the Solaris Cluster component of Oracle Sun Systems Products Suite (subcomponent: Cluster Geo). The supported version that is affected is 4.3. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Solaris Cluster executes to compromise Solaris Cluster. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Solaris Cluster accessible data as well as unauthorized update, insert or delete access to some of Solaris Cluster accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Solaris Cluster. CVSS 3.0 Base Score 6.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L).

Matched remediation archetype

Resource exhaustion and denial of service

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
