CVE-2021-35541: Vulnerability in the PeopleSoft Enterprise SCM product of Oracle PeopleSoft (component: Supplier Portal).

Vulnerability in the PeopleSoft Enterprise SCM product of Oracle PeopleSoft (component: Supplier Portal). The supported version that is affected is 9.2. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise SCM. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise SCM, 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 SCM accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise SCM accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

Oracle PeopleSoft Enterprise SCM 9.2 Supplier Portal has a medium-severity flaw that could let a low-privileged network attacker alter or read some SCM data if another user interacts with the attack. The business risk is data integrity and limited confidentiality impact in supplier or purchasing workflows, not system outage.

Executive priority

Prioritize remediation on internet- or partner-facing PeopleSoft Supplier Portal deployments, especially where supplier or purchasing data integrity is business-critical. This is not a KEV-driven emergency, but it should be handled in normal Oracle CPU patch governance.

Technical view

CVE-2021-35541 affects PeopleSoft Enterprise SCM Purchasing/Supplier Portal 9.2. CVSS 3.1 is 5.4: network exploitable, low attack complexity, low privileges required, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact. No CWE or root-cause detail is provided in the source bundle.

Likely exposure

Organizations running Oracle PeopleSoft Enterprise SCM Purchasing 9.2 with Supplier Portal reachable over HTTP are the likely exposed population. Exposure depends on deployment, access controls, and whether Oracle’s October 2021 CPU or later relevant guidance has been applied.

Exploitation context

The sources do not report active exploitation, and CISA KEV status is false. Exploitation requires a low-privileged attacker with HTTP network access and interaction by another person, limiting immediacy but still creating risk to SCM data integrity.

Researcher notes

The evidence identifies product, version, access vector, privileges, user interaction, and impact, but not the underlying flaw class or exploit mechanics. Do not assume broader PeopleSoft products are affected beyond the listed SCM Purchasing/Supplier Portal 9.2 scope.

Mitigation direction

  • Review Oracle October 2021 CPU guidance for PeopleSoft Enterprise SCM 9.2.
  • Apply the applicable Oracle security update or later vendor-approved bundle.
  • Limit Supplier Portal HTTP access to trusted networks where feasible.
  • Review low-privileged Supplier Portal roles and remove unnecessary access.
  • Monitor SCM records for unauthorized read or modification activity.

Validation and detection

  • Inventory PeopleSoft Enterprise SCM Purchasing and Supplier Portal instances.
  • Confirm whether version 9.2 is present in production or exposed environments.
  • Check patch level against Oracle’s October 2021 CPU guidance.
  • Verify Supplier Portal HTTP reachability from internal, partner, and internet paths.
  • Review audit logs for unexpected SCM data updates, inserts, deletes, or reads.
