CVE-2018-2857 — Oracle Sun Zfs Storage Appliance Kit security vulnerability

Medium CVSS 6.5

Vulnerability in the Sun ZFS Storage Appliance Kit (AK) component of Oracle Sun Systems Products Suite (subcomponent: HTTP data path subsystems). The supported version that is affected is Prior to 8.7.17. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Sun ZFS Storage Appliance Kit (AK). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Sun ZFS Storage Appliance Kit (AK) accessible data as well as unauthorized read access to a subset of Sun ZFS Storage Appliance Kit (AK) accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Sun ZFS Storage Appliance Kit (AK). CVSS 3.0 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/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.
