CVE-2020-2556 — Vulnerability in the Primavera P6 Enterprise Project Portfolio Management product of Oracle Construction and Engineering (component: Core)

High CVSS 7.3

Vulnerability in the Primavera P6 Enterprise Project Portfolio Management product of Oracle Construction and Engineering (component: Core). Supported versions that are affected are 16.2.0.0-16.2.19.0, 17.12.0.0-17.12.16.0, 18.8.0.0-18.8.16.0, 19.12.0.0 and 20.1.0.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Primavera P6 Enterprise Project Portfolio Management executes to compromise Primavera P6 Enterprise Project Portfolio Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Primavera P6 Enterprise Project Portfolio Management, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Primavera P6 Enterprise Project Portfolio Management accessible data as well as unauthorized read access to a subset of Primavera P6 Enterprise Project Portfolio Management accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Primavera P6 Enterprise Project Portfolio Management.

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.
