CVE-2020-2854: Vulnerability in the Oracle Advanced Outbound Telephony product of Oracle E-Business Suite (component: User...

Vulnerability in the Oracle Advanced Outbound Telephony product of Oracle E-Business Suite (component: User Interface). Supported versions that are affected are 12.1.1-12.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Advanced Outbound Telephony. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Advanced Outbound Telephony, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Advanced Outbound Telephony accessible data as well as unauthorized update, insert or delete access to some of Oracle Advanced Outbound Telephony accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

This vulnerability affects Oracle Advanced Outbound Telephony in Oracle E-Business Suite 12.1.1 through 12.1.3. An unauthenticated attacker with HTTP network access could compromise the product if a separate user interaction occurs, potentially exposing critical data and allowing some unauthorized data changes.

Executive priority

High priority where affected Oracle E-Business Suite versions are present. The main business risk is unauthorized access to critical data, with some risk of unauthorized data modification. Prioritize patch verification and exposure reduction.

Technical view

CVE-2020-2854 is an Oracle E-Business Suite Advanced Outbound Telephony User Interface vulnerability. CVSS 3.0 is 8.2 with AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N, indicating network reachability, no privileges, required user interaction, changed scope, high confidentiality impact, and low integrity impact.

Likely exposure

Exposure is limited to organizations running Oracle Advanced Outbound Telephony versions 12.1.1 through 12.1.3, especially where Oracle E-Business Suite is reachable over HTTP by untrusted users or networks.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Oracle describes the issue as easily exploitable over HTTP without authentication, but requiring human interaction by someone other than the attacker.

Researcher notes

No CWE is provided in the bundle. The changed-scope CVSS vector suggests impact may extend beyond the vulnerable component, consistent with Oracle's note that additional products may be significantly impacted. Evidence is insufficient to identify the exact UI flaw class.

Mitigation direction

  • Apply Oracle's April 2020 Critical Patch Update guidance for Oracle E-Business Suite.
  • Confirm whether Advanced Outbound Telephony is installed and running.
  • Restrict HTTP access to Oracle E-Business Suite to trusted networks where possible.
  • Prioritize systems exposing Oracle E-Business Suite to external or broad internal networks.
  • Review Oracle guidance for any version-specific remediation details.

Validation and detection

  • Inventory Oracle E-Business Suite deployments and enabled modules.
  • Verify Advanced Outbound Telephony version is not 12.1.1 through 12.1.3 unpatched.
  • Check patch records against Oracle's April 2020 CPU advisory.
  • Review access paths to HTTP interfaces for unnecessary exposure.
  • Monitor for unusual access to Advanced Outbound Telephony data.
