CVE-2025-36034
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 · uneditedIBM InfoSphere DataStage Flow Designer in IBM InfoSphere Information Server 11.7 discloses sensitive user information in API requests in clear text that could be intercepted using man in the middle techniques.
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 · high confidenceIBM InfoSphere DataStage Flow Designer in version 11.7 transmits sensitive user credentials and authentication information in clear text (unencrypted HTTP) within API requests. An attacker with network positioning could intercept these plaintext credentials via man-in-the-middle attacks, leading to unauthorized access to the system.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm installed IBM InfoSphere DataStage Flow Designer versionLocate and inspect the installed version of IBM InfoSphere DataStage Flow Designer or IBM InfoSphere Information Server using the product's version information utility, installation directory, or system inventoryAffected if The installed version is 11.7 (exact match to the affected version)
-
Identify API endpoint protocol configurationExamine the configuration files or administration console for the DataStage Flow Designer API endpoints to determine whether they are configured to accept HTTP or HTTPS connectionsAffected if API endpoints are configured to accept unencrypted HTTP connections (typically port 80)
-
Verify TLS/SSL is not enforced for web interfaceCheck the web server or application server configuration for IBM InfoSphere Information Server to see if TLS/SSL is enabled and enforced for all communicationsAffected if TLS/SSL encryption is disabled or set to optional/not enforced for the web interface and API access
-
Inspect network listeners for unencrypted credential transmissionReview the DataStage Flow Designer service configuration to identify which network ports and protocols are enabled for authentication and API requestsAffected if Authentication endpoints or API services are listening on unencrypted ports without TLS wrapping
A user is affected if they are running version 11.7 of IBM InfoSphere DataStage Flow Designer and their API or web interface communications are configured to allow unencrypted HTTP connections, exposing credentials to potential interception.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataEnable and enforce TLS/SSL encryption (HTTPS) for all API communications and web interface access. Ensure all sensitive data transmission occurs over encrypted channels and implement certificate validation.
