CVE-2012-5937
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 · uneditedUnspecified vulnerability in the CLA2 server in IBM Gentran Integration Suite 4.3, Sterling Integrator 5.0 and 5.1, and Sterling B2B Integrator 5.2, as used in IBM Sterling File Gateway 1.1 through 2.2 and other products, allows remote attackers to execute arbitrary commands via unknown vectors.
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 confidenceVulnerability in the CLA2 server component of IBM Gentran Integration Suite, Sterling Integrator, and Sterling B2B Integrator allows remote attackers to execute arbitrary operating system commands, likely through insufficient input validation or authentication bypass in the CLA2 protocol handler.

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 productCheck the installed product name and version by reviewing the application about page, installation directory, or version file. For Sterling products, this is typically found in the admin console or in the installation root directory.Affected if The product is IBM Gentran Integration Suite version 4.3, IBM Sterling B2B Integrator version 5.2, IBM Sterling File Gateway versions 1.1, 2.0, 2.1, or 2.2, or IBM Sterling Integrator versions 5.0 or 5.1.
-
Locate the CLA2 server componentIdentify whether the CLA2 server component is installed and configured on the system. Check for CLA2-related services, configuration files, or the presence of the CLA2 protocol handler in the product installation.Affected if The CLA2 server component is present and enabled on the system.
-
Check CLA2 network listener statusIdentify the network ports and listeners configured for the CLA2 server. This is typically found in the product's configuration files or server settings that define CLA2 listener ports.Affected if A network-accessible listener is bound to a port for CLA2 communications.
-
Verify CLA2 service accessibilityDetermine if the CLA2 service is reachable over the network from external systems. Check firewall rules, access control lists, or network exposure settings that control inbound access to the CLA2 port.Affected if The CLA2 service port is accessible from untrusted networks or external systems.
The environment is affected if the installed product version matches one of the affected versions listed AND the CLA2 server component is enabled and network-accessible.
