CVE-2021-35568: Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Rich Text E...

Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Rich Text Editor). Supported versions that are affected are 8.57, 8.58 and 8.59. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise PeopleTools, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of PeopleSoft Enterprise PeopleTools accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise PeopleTools accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

This flaw affects Oracle PeopleSoft PeopleTools rich text editor in versions 8.57, 8.58, and 8.59. An unauthenticated attacker reachable over HTTP could abuse it if they can get another person to interact. Impact is limited data reading and limited unauthorized data changes, not system takeover or outage based on the provided CVSS.

Executive priority

Treat this as a near-term business risk, not an emergency absent exploitation evidence. Prioritize faster if PeopleSoft stores HR, payroll, financial, or identity data, or if HTTP access is broadly exposed.

Technical view

CVE-2021-35568 is a network-accessible PeopleSoft Enterprise PeopleTools vulnerability in the Rich Text Editor component. CVSS 3.1 is 6.1: low attack complexity, no privileges required, user interaction required, changed scope, low confidentiality and integrity impact, and no availability impact. No CWE is provided in the source bundle.

Likely exposure

Organizations running Oracle PeopleSoft Enterprise PT PeopleTools 8.57, 8.58, or 8.59 are in scope, especially where PeopleSoft HTTP services are reachable by users or externally exposed.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires network access via HTTP and human interaction by someone other than the attacker, reducing immediacy but keeping phishing-style abuse plausible.

Researcher notes

Evidence is limited to official CVE details and Oracle CPU reference. The bundle names the affected component and versions but does not include CWE, exploit details, indicators of compromise, or exact fixed build numbers.

Mitigation direction

  • Review Oracle’s October 2021 Critical Patch Update for PeopleSoft guidance.
  • Apply vendor-recommended PeopleTools security updates for affected versions.
  • Restrict HTTP access to PeopleSoft to trusted networks where possible.
  • Prioritize remediation for internet-facing or high-sensitivity PeopleSoft environments.

Validation and detection

  • Inventory PeopleTools versions and identify any 8.57, 8.58, or 8.59 systems.
  • Confirm whether Oracle October 2021 CPU fixes are installed.
  • Map PeopleSoft HTTP exposure across internet, VPN, and internal networks.
  • Review PeopleSoft logs for unusual data reads or modification activity.
