Vulnerability in the PeopleSoft Enterprise CS Student Records product of Oracle PeopleSoft (component: Class Search). 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 CS Student Records. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise CS Student Records, 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 CS Student Records accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise CS Student Records 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

This flaw affects Oracle PeopleSoft Enterprise CS Student Records 9.2, specifically Class Search. A low-privileged user reachable over HTTP could, with another person’s interaction, read some student-record data and modify some accessible data. The public sources do not show active exploitation.

Executive priority

Treat as a moderate-priority remediation item. Prioritize faster if PeopleSoft is internet-accessible, broadly available to low-privileged users, or stores sensitive student data subject to compliance obligations.

Technical view

CVE-2021-35553 is a network-exploitable PeopleSoft Class Search vulnerability with low attack complexity, low privileges required, and required user interaction. CVSS 3.1 is 5.4 with low confidentiality and integrity impact, no availability impact, and changed scope. No CWE is listed in the provided sources.

Likely exposure

Likely exposed environments are institutions running PeopleSoft Enterprise CS Student Records 9.2 with Class Search available over HTTP to low-privileged users.

Exploitation context

The source says exploitation requires network access via HTTP, a low-privileged attacker, and human interaction from someone else. KEV is false, and the provided sources do not cite active exploitation or public exploit use.

Researcher notes

Public detail is limited. The advisory identifies Class Search, version 9.2, and data read/write impacts, but does not provide a CWE, root cause, named exploit technique, or confirmed exploitation evidence in the supplied bundle.

Mitigation direction

  • Review Oracle October 2021 Critical Patch Update guidance for this PeopleSoft issue.
  • Apply the relevant Oracle-supplied fixes for PeopleSoft Enterprise CS Student Records 9.2.
  • Limit HTTP access to PeopleSoft Class Search where operationally possible.
  • Review low-privileged PeopleSoft roles with access to Student Records functions.
  • Monitor Student Records read and write activity for unexpected access patterns.

Validation and detection

  • Confirm whether PeopleSoft Enterprise CS Student Records 9.2 is deployed.
  • Identify whether the Class Search component is enabled and HTTP-accessible.
  • Compare PeopleSoft patch levels against Oracle October 2021 CPU guidance.
  • Review logs for unusual student-record reads, updates, inserts, or deletes.
  • Verify low-privileged accounts cannot perform unintended Student Records actions.
