CVE-2022-34310
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 CICS TX Standard and Advanced 11.1 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 229441.
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 CICS TX Standard and Advanced version 11.1 uses weaker than expected cryptographic algorithms, which could allow an attacker to decrypt highly sensitive information that was protected using these weak algorithms.

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 IBM CICS TX installed versionUse the system inventory tool or version command for IBM CICS TX (for example, run 'cicsinfo' or check the product documentation for the version reporting command specific to your installation)Affected if The installed version is 11.1.0.0 or any version below 11.1.0.0 (for example, 11.0.x, 10.x)
-
Confirm the CICS TX editionVerify whether the installation is IBM CICS TX Standard or Advanced edition, as both are affectedAffected if The edition is CICS TX Standard or Advanced version 11.1.0.0 or lower
-
Determine if sensitive data is encryptedReview your data storage or configuration to identify whether any highly sensitive information (such as passwords, keys, personal data, or financial records) is protected using IBM CICS TX built-in encryption featuresAffected if Sensitive data is encrypted using the system's native encryption capabilities in an affected version
-
Review cryptographic configurationExamine the CICS TX configuration files or cryptographic settings for any non-FIPS compliant algorithm usage (consult IBM documentation for the specific configuration location in your environment)Affected if Weak or non-FIPS 140-2 compliant cryptographic algorithms are configured or in use
You are affected if IBM CICS TX Standard or Advanced version 11.1.0.0 or any lower version is installed and sensitive data is protected using the system's encryption features.
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.

Apply IBM patches for CVE-2022-34310 to upgrade to stronger cryptographic algorithms, or re-encrypt sensitive data using FIPS 140-2 compliant algorithms if patches are not immediately available.
IBM CICS TX 11.1.0.1 or later fix pack
- Check current IBM CICS TX version using the console or system commands
- Review IBM's official support portal for CICS TX 11.1 fix packs and interim fixes
- Download and apply IBM CICS TX 11.1.0.1 or later fix pack which addresses the weak cryptographic algorithms vulnerability
- After upgrade, verify the cryptographic configuration uses strong algorithms (AES-256, SHA-256 or stronger)
- Restart CICS TX services as required by the fix pack installation
