Details

LG Simple Editor saveXmlFile XML External Entity Processing Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of LG Simple Editor. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the saveXmlFile method. Due to the improper restriction of XML External Entity (XXE) references, a crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage this vulnerability to disclose information in the context of SYSTEM. Was ZDI-CAN-19952.

Summary
TYPO3 ke_search XML External Entity Injection
Details

In TYPO3 faceted fulltext search (ke_search), the OOXML parsing of the file indexer does not disable external entity resolution. A crafted xlsx or pptx document placed in an indexed directory can cause local files to be read or outbound HTTP requests to be performed, with the retrieved content being written to the search index. This has been patched in versions 7.0.1, 6.6.1, 5.6.2 and 4.6.7.

Details

proCertum SmartSign parses external XML entities from arbitrary crafted signature files, enabling SSRF and potentially allowing the reading of local files, depending on the parser's configuration. The XML External Entity (XXE) vulnerability is triggered simply by previewing a file in the file selection window, before the victim clicks “Open”.

This issue was fixed in version 9.4.3.90.

Vulnerability from github – Published: 2025-04-17 00:30 – Updated: 2025-04-17 00:30
VLAI
Details

Overview

XML documents optionally contain a Document Type Definition (DTD), which, among other features, enables the definition of XML entities. It is possible to define an entity by providing a substitution string in the form of a URI. Once the content of the URI is read, it is fed back into the application that is processing the XML. This application may echo back the data (e.g. in an error message), thereby exposing the file contents. (CWE-611)

Description

Hitachi Vantara Pentaho Business Analytics Server versions before 10.2.0.2, including 9.3.x and 8.3.x, do not correctly protect Data Access XMLParserFactoryProducer against out-of-band XML External Entity Reference.

Impact

By submitting an XML file that defines an external entity with a file:// URI, an attacker can cause the processing application to read the contents of a local file. Using URIs with other schemes such as http://, the attacker can force the application to make outgoing requests to servers that the attacker cannot reach directly, which can be used to bypass firewall restrictions or hide the source of attacks such as port scanning.

It is possible to define an entity by providing a substitution string in the form of a URI. Once the content of the URI is read, it is fed back into the application that is processing the XML. This application may echo back the data (e.g. in an error message), thereby exposing the file contents.

Using URIs with other schemes such as http://, the attacker can force the application to make outgoing requests to servers that the attacker cannot reach directly, which can be used to bypass firewall restrictions or hide the source of attacks such as port scanning.",

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.
