CVE-2023-35892
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 Financial Transaction Manager for SWIFT Services 3.2.4 is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 258786.
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 Financial Transaction Manager for SWIFT Services 3.2.4 is vulnerable to XML External Entity Injection (XXE) when processing XML data. A remote attacker can exploit this by injecting malicious external entity references to expose sensitive information from the file system or internal network, or cause memory resource exhaustion through recursive entity expansion.

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 version of IBM Financial Transaction Manager for SWIFT ServicesRun the version check command or inspect the product's 'About' information. On Linux, this may be found via the installation directory's version manifest or using the IBM installation manager. On Windows, check the program's properties in Add/Remove Programs.Affected if The installed version is exactly 3.2.4.
-
Locate XML parser configuration files used by the applicationSearch the application installation directory for XML parser configuration files such as parser-config.xml, xerces-config.xml, or similar. Check the conf/ or config/ subdirectories for files that control XML processing behavior.Affected if XXE-prone parser configurations exist and are in use by the application.
-
Check if external entity resolution is enabled in XML parsersOpen the XML parser configuration files and look for settings such as 'externalEntityEnabled', 'allowExternalEntities', or 'resolveExternalEntities'. Verify whether these are set to 'true' or not explicitly disabled.Affected if External entity resolution is enabled (set to true or not explicitly disabled) in the parser configuration.
-
Check if DTD processing is enabled in XML parsersInspect the same XML parser configuration files for settings like 'allowDTD', 'processDTD', or 'enableDTD'. Determine if DTD processing is permitted.Affected if DTD processing is enabled in the XML parser configuration.
A user is affected if they have IBM Financial Transaction Manager for SWIFT Services version 3.2.4 installed AND their XML parser configuration allows external entity resolution or DTD processing.

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 dataApply IBM's vendor patch for this vulnerability. As an interim control, disable external entity resolution and DTD processing in all XML parsers used by the application, and implement strict input validation for all XML data before parsing.
