CVE intelligence and bounded remediation

CVE-2018-16956 — Oracle Webcenter Interaction security vulnerability

Medium CVSS 6.5

The AjaxControl component of Oracle WebCenter Interaction Portal 10.3.3 does not validate the names of pages when processing page rename requests. Pages can be renamed to include characters unsupported for URIs by the web server hosting the WCI Portal software (such as IIS). Renaming pages to include unsupported characters, such as 0x7f, prevents these pages from being accessed over the web server, causing a Denial of Service (DoS) to the page. NOTE: this CVE is assigned by MITRE and isn't validated by Oracle because Oracle WebCenter Interaction Portal is out of support.

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.
