CVE-2020-2871: 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 and 12.2.3-12.2.9. 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 is a high-severity Oracle E-Business Suite issue in Advanced Outbound Telephony. An unauthenticated attacker with HTTP network access could compromise sensitive telephony-accessible data if they can get a user to interact. The main business risk is unauthorized data access, with some ability to alter records.

Executive priority

Treat as a prompt patching and exposure-reduction item for any affected E-Business Suite environment. It is high risk because no attacker login is required and sensitive data could be exposed, but the sources do not establish active exploitation.

Technical view

CVE-2020-2871 affects Oracle Advanced Outbound Telephony in E-Business Suite versions 12.1.1-12.1.3 and 12.2.3-12.2.9. The vector is network-accessible HTTP, no privileges required, user interaction required, changed scope, high confidentiality impact, low integrity impact, and no availability impact. CVSS v3.0 score is 8.2.

Likely exposure

Exposure is limited to organizations running the affected Oracle Advanced Outbound Telephony versions, especially where E-Business Suite HTTP interfaces are reachable by untrusted networks or users can be targeted for interaction.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. Exploitation is described as easy, unauthenticated, and network-based via HTTP, but it requires interaction from a person other than the attacker.

Researcher notes

Key constraints are affected version matching, HTTP reachability, and required victim interaction. The scope-changed CVSS vector indicates impact may extend beyond the vulnerable component. The source bundle does not provide CWE detail, exploit status, or exact fixed version mapping.

Mitigation direction

  • Identify affected Oracle E-Business Suite Advanced Outbound Telephony deployments.
  • Apply Oracle's April 2020 Critical Patch Update or current vendor guidance.
  • Restrict HTTP access to trusted networks where feasible.
  • Review exposure of E-Business Suite interfaces to the internet.
  • Prioritize systems holding sensitive customer or operational telephony data.

Validation and detection

  • Confirm Oracle E-Business Suite and Advanced Outbound Telephony versions.
  • Check patch records against Oracle CPU April 2020 guidance.
  • Verify whether affected HTTP interfaces are externally reachable.
  • Review access logs for unusual unauthenticated activity.
  • Confirm compensating network controls are active.
