CVE-2025-64648
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 Concert 1.0.0 through 2.2.0 transmits data in clear text that could allow an attacker to obtain sensitive information 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 · moderate confidenceIBM Concert versions 1.0.0 through 2.2.0 transmits sensitive data in cleartext without encryption, allowing man-in-the-middle attackers to intercept and read confidential information during network transit.

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.
-
Identify installed IBM Concert versionRun the command to display the IBM Concert version (e.g., 'concert --version', 'ibm-concert --version', or check the product's About/Version information in the UI)Affected if The displayed version is 1.0.0, 1.x.x, 2.0.x, 2.1.x, or 2.2.0 (any version from 1.0.0 through 2.2.0)
-
Locate IBM Concert configuration filesSearch for configuration files in the IBM Concert installation directory, commonly named 'config', 'settings', or similar directories, or check user/home directories for configurationAffected if Configuration files exist but contain no TLS/SSL or encryption settings, or settings explicitly disable encryption
-
Verify TLS/SSL encryption configurationOpen the main configuration file and look for keywords such as 'ssl', 'tls', 'https', 'encryption', 'secure', 'cert', or 'certificate'Affected if No TLS/SSL settings are found, or encryption is explicitly disabled or set to 'none' or 'false'
-
Check connection strings or endpoint URLsExamine configuration files, connection profiles, or environment variables that define IBM Concert server URLs or API endpointsAffected if URLs use 'http://' instead of 'https://', indicating unencrypted communication
You are affected if the installed IBM Concert version is 1.0.0 through 2.2.0 and TLS/SSL encryption is not enabled in the configuration, as the product transmits data in cleartext.
Generated from the published advisory. Verify against your own configuration.
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 TLS/SSL encryption for all network communications in IBM Concert, or upgrade to version 2.2.1 or later if a patched release is available.
