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
The Interior Server and Gateway Server components of TIBCO Software Inc.'s TIBCO PartnerExpress contain easily exploitable Stored and Reflected Cross Site Scripting (XSS) vulnerabilities that allow a low privileged attacker to social engineer a legitimate user with network access to execute scripts targeting the affected system or the victim's local system. A successful attack using this vulnerability requires human interaction from a person other than the attacker. Affected releases are TIBCO Software Inc.'s TIBCO PartnerExpress: versions 6.2.1 and below.

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

TIBCO PartnerExpress versions 6.2.1 and below contain both Stored and Reflected XSS vulnerabilities in the Interior Server and Gateway Server components. A low-privileged attacker can inject malicious scripts that persist in the system (Stored XSS) or are reflected back to victims (Reflected XSS), targeting either the affected system or the victim's local browser through social engineering.

MitigationUpgrade TIBCO PartnerExpress to a version above 6.2.1. Implement input validation, output encoding, and Content Security Policy headers as compensating controls until the upgrade is completed.

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. Identify if TIBCO PartnerExpress is installed
    Check for the presence of TIBCO PartnerExpress installation directory (commonly under C:\tibco\partnerexpress or /opt/tibco/partnerexpress on Linux), or look for running services named 'PartnerExpress', 'TibcoPE', or similar in system services list.
    Affected if The software is found installed on the system regardless of version
  2. Determine installed version of TIBCO PartnerExpress
    Locate the version file or check product details: in Windows, look in the installation directory for a version.txt, about.html, or check the program's properties. On Linux, check /opt/tibco/partnerexpress/version or similar. Alternatively, access the product's web interface and look for version information in the footer or help/about section.
    Affected if Installed version is 6.2.1 or lower (any version <= 6.2.1)
  3. Check if Interior Server component is accessible
    Attempt to access the Interior Server web interface if exposed: typical default ports include 8080, 8443, or 18080. Check network listeners or firewall rules for services running on these ports, or review server configuration files for enabled web endpoints.
    Affected if Interior Server web interface is exposed and version is <= 6.2.1
  4. Check if Gateway Server component is accessible
    Attempt to access the Gateway Server web interface if exposed: common default ports include 8080, 8443, or 18080. Review configuration files (such as server.xml or gateway-config.xml) in the installation directory for exposed endpoints, or check network listening services.
    Affected if Gateway Server web interface is exposed and version is <= 6.2.1
  5. Verify low-privileged user access exists
    Review user management configuration or Active Directory integration to confirm if low-privileged accounts (non-admin roles) can access the web interfaces of Interior Server or Gateway Server.
    Affected if Low-privileged users have access to the web interfaces and the installed version is <= 6.2.1

You are affected if TIBCO PartnerExpress version 6.2.1 or lower is installed and either the Interior Server or Gateway Server web components are accessible to users.
