CVE-2024-47582
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 · uneditedDue to missing validation of XML input, an unauthenticated attacker could send malicious input to an endpoint which leads to XML Entity Expansion attack. This causes limited impact on availability of the application.
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 confidenceThis is an XML External Entity (XXE) vulnerability caused by missing validation of XML input. An unauthenticated attacker can send malicious XML with entity expansion (e.g., billion laughs attack) to an endpoint, causing resource exhaustion and limited availability impact.

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 XML input endpointsReview application logs, API documentation, or network traffic to find endpoints accepting XML data (Content-Type: application/xml, text/xml, or XML in request body)Affected if The system accepts unauthenticated XML input at any endpoint without documented XXE protections
-
Examine XML parser configurationLocate XML parser initialization code or configuration files and check for settings controlling external entity processing such as 'external-general-entities', 'external-parameter-entities', or 'allow-dtd'Affected if External entity processing or DTD parsing is explicitly enabled or defaults to enabled in the XML parser
-
Verify entity expansion protectionInspect XML parser settings for protections against billion laughs attack, such as entity expansion limits, XXE disable flags, or FEATURE_SECURE_PROCESSINGAffected if The XML parser lacks entity expansion limits or explicit XXE protection settings and accepts untrusted XML input
-
Check XML input validationReview application code that handles XML requests to determine if schema validation (XSD) or input sanitization is performed before parsingAffected if XML input is parsed without prior validation against a schema or sanitization of potentially malicious entity declarations
A system is affected by this CVE if it accepts unauthenticated XML input and its XML parser has external entities and DTD processing enabled without entity expansion limits or input validation.

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 and DTD parsing in XML parsers. Implement proper XML input validation and sanitization. Use secure XML parser configurations that prevent entity expansion.
