CVE-2023-39482
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 · uneditedSofting Secure Integration Server Hardcoded Cryptographic Key Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Softing Secure Integration Server. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within libopcuaclient.so. The issue results from hardcoding crytographic keys within the product. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-20610.
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 confidenceHardcoded cryptographic keys embedded in libopcuaclient.so of Softing Secure Integration Server allow authenticated attackers (or those bypassing authentication) to disclose stored credentials. The flaw enables further compromise by exposing sensitive authentication material stored by the product.

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 product versionRun the product's version command or check its about/info panel. For Softing Edgeaggregator, Edgeconnector, or Secure Integration Server, use: docker ps (if containerized) or check the installed package version via the system package manager. Look for version information in /opt/softing/ or the product's installation directory.Affected if The installed version is less than 3.70 for Edgeaggregator/Edgeconnector, or less than 1.30 for Secure Integration Server.
-
Locate libopcuaclient.so library fileSearch for the vulnerable library: find / -name 'libopcuaclient.so' 2>/dev/null or check in common installation paths like /opt/softing/, /usr/lib/, or the product's bin/lib directory. Use 'ls -la' on the found file to confirm its presence and modification date.Affected if The library file exists on the system, indicating the vulnerable component is present.
-
Verify credential storage is in useCheck the product's configuration files or database for stored credentials. Look for credential-related directories (often named 'credentials', 'certs', 'keys', 'security') or configuration files (XML, JSON, YAML) that may contain encrypted or stored authentication material. Inspect the data directory where the product stores user credentials or integration credentials.Affected if The product is configured to store credentials (user accounts, integration credentials, or authentication tokens) that would be protected by the hardcoded keys.
-
Review authentication configurationExamine the product's authentication settings in its configuration files or admin interface. Check whether authentication is enabled and whether the product stores credentials locally. Look for settings related to user authentication, API keys, or integration credentials stored on the system.Affected if Local authentication storage is enabled, meaning the hardcoded keys could be used to decrypt stored credentials.
A system is affected if it runs any of the three Softing products with a version below the threshold AND has the libopcuaclient.so library present with stored credentials that rely on the hardcoded cryptographic keys.

Replace hardcoded cryptographic keys with properly managed keys, rotate any exposed credentials, and apply vendor patches if available. Review access controls and monitor for credential reuse across systems.
