CVE-2024-31903
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 Sterling B2B Integrator Standard Edition 6.0.0.0 through 6.1.2.5 and 6.2.0.0 through 6.2.0.2 allow an attacker on the local network to execute arbitrary code on the system, caused by the deserialization of untrusted data.
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 Sterling B2B Integrator Standard Edition versions 6.0.0.0-6.1.2.5 and 6.2.0.0-6.2.0.2 contain a deserialization vulnerability where the application deserializes untrusted data without proper validation. An attacker on the local network can exploit this to execute arbitrary code on the affected 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.
-
Identify the installed IBM Sterling B2B Integrator versionLocate the product version through the administrative console, installation directory, or version lookup command provided in the product documentationAffected if The version falls within 6.0.0.0-6.1.2.5 or 6.2.0.0-6.2.0.2
-
Verify the exact version numberConfirm the full version string including any build numbers or patches applied to the installationAffected if The version is equal to or lower than 6.1.2.5 (for 6.0.x-6.1.x releases) or equal to or lower than 6.2.0.2 (for 6.2.x releases)
-
Determine network accessibility of the affected serviceReview firewall rules, network segmentation, and access control lists to determine if the IBM Sterling B2B Integrator ports and services are accessible from untrusted network segmentsAffected if The system is reachable from network segments that contain untrusted or non-administrative users
-
Identify exposed deserialization endpointsReview the application's exposed HTTP endpoints, APIs, or integration channels that accept serialized data input from external sourcesAffected if The application exposes endpoints that process serialized data without additional authentication or validation layers
The environment is affected if the installed IBM Sterling B2B Integrator version falls within 6.0.0.0-6.1.2.5 or 6.2.0.0-6.2.0.2 and the deserialization functionality is accessible to network attackers.

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.
dbcve · scopedUpgrade to IBM Sterling B2B Integrator version 6.1.2.6 or 6.2.0.3 or later. If immediate patching is not feasible, restrict network access to the affected system using network segmentation and firewall rules to limit exposure to only trusted network segments.
IBM Sterling B2B Integrator 6.2.0.3 or later (or the specific interim fix for your current version)
- 1. Obtain the latest IBM Sterling B2B Integrator interim fix (APAR) for this vulnerability from IBM Support - search for the APAR reference associated with CVE-2024-31903
- 2. Review IBM's published security bulletin for this CVE to identify the specific interim fix number and download instructions
- 3. Schedule a maintenance window for the upgrade
- 4. Back up the current Sterling B2B Integrator configuration and database
- 5. Apply the IBM interim fix following the instructions in the fix readme or IBM documentation
- 6. Verify the fix was applied successfully by checking the installed fix levels
- 7. Test critical business workflows to ensure the system functions correctly after the patch
