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 Replay Server in IBM Tealeaf Customer Experience 8.x before 8.7.1.8847 FP10, 8.8.x before 8.8.0.9049 FP9, 9.0.0 and 9.0.1 before 9.0.1.1117 FP5, 9.0.1A before 9.0.1.5108 FP5, 9.0.2 before 9.0.2.1223 FP3, and 9.0.2A before 9.0.2.5224 FP3 allows remote attackers to conduct SSRF attacks via unspecified vectors.

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

This is a Server-Side Request Forgery (SSRF) vulnerability in the Replay Server component of IBM Tealeaf Customer Experience. The vulnerability allows remote unauthenticated attackers to coerce the Replay Server into making arbitrary HTTP requests to internal or external resources, potentially bypassing network boundaries.

MitigationApply the vendor-supplied patches for the specific FP (Fix Pack) versions corresponding to each affected release line (8.7.1.8847 FP10, 8.8.0.9049 FP9, 9.0.1.1117 FP5, 9.0.1.5108 FP5, 9.0.2.1223 FP3, or 9.0.2.5224 FP3). Additionally, implement network segmentation and restrict outbound connectivity from the Replay Server to minimize impact of any SSRF exploitation.

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 Tealeaf Replay Server component is installed
    Check for the presence of Tealeaf Replay Server in the installed components. Look for directories named 'ReplayServer' or similar under the Tealeaf installation path, or check Windows Services/Unix init scripts for a 'Tealeaf Replay Server' or 'ReplayServer' service.
    Affected if The Replay Server component is present and running on the system
  2. Determine installed Tealeaf Customer Experience version
    Locate the Tealeaf installation directory and look for a version file, about dialog, or check registry entries (on Windows) that indicate the exact version number. Common locations include the main Tealeaf installation folder or within product documentation.
    Affected if The installed version matches <= 8.6, 8.7, 8.8, 9.0.0, 9.0.0a, 9.0.1, 9.0.1a, 9.0.2, or 9.0.2a
  3. Confirm Replay Server is exposed on the network
    Identify the port used by Replay Server (typically configurable, default may be 8080, 8090, or similar) and verify if the service is listening on a network interface accessible to unauthenticated remote attackers. Check firewall rules and binding configuration.
    Affected if Replay Server listens on a network-accessible interface and is reachable without authentication from untrusted networks
  4. Check for recent access logs indicating SSRF activity
    Review Replay Server access logs for suspicious patterns such as internal IP addresses (127.0.0.1, 10.x.x.x, 192.168.x.x), unusual HTTP headers, or requests to unexpected internal resources.
    Affected if Logs show requests to internal resources or unexpected external domains that were not initiated by legitimate users

You are affected if the Replay Server component is installed and the installed Tealeaf version matches the affected version list, particularly if the service is network-accessible.
