CVE-2021-2051 — Vulnerability in the Oracle BI Publisher product of Oracle Fusion Middleware (component: E-Business Suite - XDO)

High CVSS 7.6

Vulnerability in the Oracle BI Publisher product of Oracle Fusion Middleware (component: E-Business Suite - XDO). Supported versions that are affected are 5.5.0.0.0, 11.1.1.9.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle BI Publisher. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle BI Publisher accessible data as well as unauthorized update, insert or delete access to some of Oracle BI Publisher accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle BI Publisher. CVSS 3.1 Base Score 7.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/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.
