CVE-2025-27903
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 DB2 Recovery Expert for LUW 5.5 Interim Fix 002 IBM Db2 Recovery Expert for Linux, UNIX and Windows transmits data in a cleartext communication channel 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 DB2 Recovery Expert for LUW transmits sensitive data over unencrypted communication channels, enabling man-in-the-middle attackers to intercept and obtain confidential information during 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.
-
Verify IBM DB2 Recovery Expert installation and versionLocate the IBM DB2 Recovery Expert installation directory and check the product version (typically found in about dialog, version file, or installation metadata). Compare your installed version to the affected range (= 5.5.0).Affected if The installed version is exactly 5.5.0 and the product is in use.
-
Identify communication configuration settingsExamine IBM DB2 Recovery Expert configuration files or settings related to network communications, database connections, or client-server communication parameters.Affected if Communication settings do not enforce TLS/SSL encryption and allow plaintext transmission.
-
Inspect SSL/TLS encryption statusReview the security or connection settings within IBM DB2 Recovery Expert to determine whether SSL/TLS encryption is enabled for data in transit.Affected if SSL/TLS encryption is disabled or not configured for communications.
-
Verify network traffic protectionIf possible, inspect network communication settings or documentation to confirm whether all communications are routed through encrypted channels.Affected if Communications can occur over unencrypted channels and sensitive data may be transmitted in plaintext.
A user is affected if IBM DB2 Recovery Expert version 5.5.0 is installed and communications are configured to allow unencrypted data transmission.

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 communications within IBM DB2 Recovery Expert or ensure communications occur over properly encrypted network paths to prevent interception.
