CVE-2023-45192
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 Engineering Requirements Management DOORS Next 7.0.2 and 7.0.3 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: 268758.
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 Engineering Requirements Management DOORS Next versions 7.0.2 and 7.0.3 are vulnerable to XML External Entity Injection (XXE) when processing XML data. A remote attacker can exploit this vulnerability by sending malicious XML requests containing external entity references, potentially exposing sensitive system files or consuming memory resources 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 installed DOORS Next versionAccess the DOORS Next admin console or use the product's About dialog to view the exact version number. Check installation logs or version files in the installation directory.Affected if version is 7.0.2 or 7.0.3 exactly
-
Verify XML processing capability is in useReview the DOORS Next configuration to determine if XML import, export, or data interchange features are enabled or actively used.Affected if XML processing features are enabled or configured for user access
-
Check XML parser security configurationExamine the XML parser settings in the DOORS Next configuration files. Look for configurations related to DOCTYPE processing, external entity resolution, and entity expansion limits.Affected if external entity processing is not explicitly disabled or secure defaults are not configured
-
Review XML-related log entriesSearch DOORS Next server logs for patterns indicating XXE payloads, such as DOCTYPE declarations, ENTITY definitions, or suspicious file access attempts via XML requests.Affected if logs contain XML requests with DOCTYPE or external entity references
A user is affected if their DOORS Next installation is exactly version 7.0.2 or 7.0.3 and the XML processing feature is enabled, with the XML parser configured to allow external entity processing.
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.
From vendor dataDisable external entity processing in the XML parser configuration and implement input validation to reject XML containing DOCTYPE declarations with external entity references. Ensure the XML parser is configured with secure defaults that prevent entity expansion attacks.
