Title
Kiteworks Email Protection Gateway Improper Restriction of XML External Entity Reference
Summary
An XML parser used by Kiteworks Email Protection Gateway did not restrict external entity references. Where an optional, non-default message-processing feature is enabled, a remote and unauthenticated sender could potentially use a crafted message to read files accessible to the gateway service account, including cryptographic key material and credentials, and have them sent to a destination they control.

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
Apache Camel Quarkus: Camel Quarkus: Forced Xalan TransformerFactory drops upstream external-DTD/stylesheet hardening
Summary
Improper Restriction of XML External Entity Reference in the XSLT support extension (camel-quarkus-support-xalan) in Apache Camel Quarkus from 3.2.0 before 3.33.3 and from 3.34.0 before 3.40.0 on all platforms allows an attacker who supplies the XML document being transformed to read local files or issue requests to internal network locations via an external entity declaration in that document. The extension supplies its own Xalan-backed TransformerFactory to the xslt component and registers it as the JAXP default. Xalan-J 2.7.x predates JAXP 1.5 and does not honour javax.xml.XMLConstants.ACCESS_EXTERNAL_DTD or ACCESS_EXTERNAL_STYLESHEET, so the external access restrictions Apache Camel applies to the TransformerFactory it creates were not in effect. On the xslt component path this affects message bodies that reach the transformer already as a javax.xml.transform.Source; bodies of other types are converted to a SAXSource by Apache Camel with external entities and external DTD loading disabled, and are not affected. Because the factory is also the JAXP default, other code in the application obtaining one through TransformerFactory.newInstance() loses the same restrictions without error. Applications are affected if they use any of camel-quarkus-xslt, camel-quarkus-xslt-saxon, camel-quarkus-tika or camel-quarkus-xmlsecurity, each of which brings the XSLT support extension onto the classpath. For all but camel-quarkus-xslt, the exposure is limited to the JAXP default factory, since those extensions do not perform XSLT transformations themselves. Users are recommended to upgrade to version 3.33.3 or 3.40.0, which fixes this issue.

Title
Omada Controller XML External Entity (XXE) Injection in SAML IdP Metadata Parsing Leading to Arbitrary Local File Read
Summary
An information disclosure vulnerability in the SAML Single Sign-On (SSO) functionality of Omada Controller allows an authenticated user with SAML configuration privileges to access sensitive information due to insufficient validation of user-supplied SAML metadata. Successful exploitation could result in unauthorized disclosure of sensitive information.

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.
