Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Vulnerability in the PeopleSoft Enterprise PRTL Interaction Hub product of Oracle PeopleSoft (component: My Links). The supported version that is affected is 9.1. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise PRTL Interaction Hub. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise PRTL Interaction Hub, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of PeopleSoft Enterprise PRTL Interaction Hub accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise PRTL Interaction Hub 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).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Cross-site scripting (XSS) vulnerability in the My Links component of PeopleSoft Enterprise PRTL Interaction Hub 9.1 allows low-privileged attackers to inject malicious scripts that execute during human interaction, enabling unauthorized read and write access to application data. The scope change indicates the attack can propagate to affect additional products in the PeopleSoft environment.

MitigationApply Oracle Critical Patch Update (CPU) for April 2022. Until patch is available, implement WAF rules for My Links endpoint, restrict network access to the application, and educate users about suspicious link clicking.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify PeopleSoft PRTL Interaction Hub version
    Access the PeopleSoft sign-in page or About page, or query the PSVERSION table for the portal application version. Compare the installed version to 9.1.
    Affected if The installed version is exactly 9.1
  2. Confirm My Links component is enabled
    Log into PeopleSoft Portal and navigate to My Links (typically under Personalize > My Links) or check the portal registry structure for the PRTL_MY_LINKS component in the PeopleTools Portal > My Links component.
    Affected if The My Links feature is accessible and active in the portal
  3. Check if My Links endpoint accepts user input
    Access the My Links functionality and attempt to create a new custom link with a name or URL containing a test script string (for example: <script>alert(1)</script>). Observe whether the input is reflected back in the page without proper encoding.
    Affected if User-supplied input in the My Links component is reflected unescaped in the page HTML
  4. Review web access logs for XSS attack signatures
    Examine web server (Oracle WebLogic/Apache) access and error logs for requests to My Links endpoints containing script tags or common XSS patterns in query parameters.
    Affected if Logs show malicious script injection attempts or unsanitized parameter reflection in recent requests

A system is affected if it runs PeopleSoft Enterprise PRTL Interaction Hub version 9.1 with the My Links component enabled and accessible, where the My Links functionality reflects user input without HTML encoding.
