Title
Flowable flowable-engine through 8.0.0 XXE via ProcessDiagramLayoutFactory
Summary
Flowable flowable-engine through 8.0.0 contains an XML external entity injection vulnerability in ProcessDiagramLayoutFactory.parseXml() that fails to disable external entity resolution when parsing deployed BPMN resources. Attackers with process deployment privileges can embed DOCTYPE declarations with external entities in BPMN files to read arbitrary local files or trigger requests to internal network endpoints when diagram layout is computed.

Title
MoguBlog through 6.2 XML External Entity Injection in the Unauthenticated WeChat Callback Endpoint
Summary
MoguBlog through 6.2 contains an XML external entity injection vulnerability in the WeChat callback handler at POST /wechat/wechatCheck. The WechatRestApi.index() method passes the raw request body to SignUtil.xmlToMap(), which uses an unhardened dom4j SAXReader without DTD or external-entity restrictions. Unauthenticated remote attackers can submit DOCTYPE declarations with external parameter entities to read arbitrary local files or trigger outbound HTTP requests, with resolved entities reflected in error responses.

Title
NextGen Healthcare Mirth Connect Improper Restriction of XML External Entity Reference
Summary
When XML batch processing is turned on and the XPath option is selected, the raw batch input goes through a default XPath/JAXP setup with no entity restrictions, so XXE injection can allow data exfiltration and denial-of-service attacks.

Title
Exterro FTK Imager < 8.3 XXE via Report.xml XSLT Processing
Summary
Exterro FTK Imager before 8.3 contains an XML external entity (XXE) injection vulnerability that allows attackers to read arbitrary files from the host filesystem by embedding malicious external entity references and attacker-controlled XSLT stylesheets within a Report.xml file inside a UFDR ZIP evidence item. Attackers can craft a malicious UFDR archive that, when previewed by an examiner, causes the XML parser to resolve file:// external entity references and execute msxsl:script within the external stylesheet to exfiltrate the resolved file contents to an attacker-controlled endpoint via a generated image URL.

Mitigation
Implementation System Configuration

Many XML parsers and validators can be configured to disable external entity expansion.

CAPEC-221: Data Serialization External Entities Blowup

This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
