Title
An XML External Entity injection vulnerability
Summary
XXE injection in /rtc/post/ endpoint in OpenMNS Horizon 31.0.8 and versions earlier than 32.0.2 on multiple platforms is vulnerable to XML external entity (XXE) injection, which can be used for instance to force Horizon to make arbitrary HTTP requests to internal and external services. The solution is to upgrade to Meridian 2023.1.6, 2022.1.19, 2021.1.30, 2020.1.38 or Horizon 32.0.2 or newer. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet. OpenNMS thanks Erik Wynter and Moshe Apelbaum for reporting this issue.

Title
Geonetwork 4.2.0 - XML External Entity (XXE)
Summary
Geonetwork 3.10 through 4.2.0 contains an XML external entity vulnerability in PDF rendering that allows attackers to retrieve arbitrary files from the server. Attackers can exploit the insecure XML parser by crafting a malicious XML document with external entity references to read system files through the baseURL parameter in PDF creation requests.

CVE-2022-46751 (GCVE-0-2022-46751)

Vulnerability from cvelistv5 – Published: 2023-08-21 06:55 – Updated: 2025-02-13 16:33

Title
Apache Ivy: XML External Entity vulnerability in Apache Ivy
Summary
Improper Restriction of XML External Entity Reference, XML Injection (aka Blind XPath Injection) vulnerability in Apache Software Foundation Apache Ivy.This issue affects any version of Apache Ivy prior to 2.5.2. When Apache Ivy prior to 2.5.2 parses XML files - either its own configuration, Ivy files or Apache Maven POMs - it will allow downloading external document type definitions and expand any entity references contained therein when used. This can be used to exfiltrate data, access resources only the machine running Ivy has access to or disturb the execution of Ivy in different ways. Starting with Ivy 2.5.2 DTD processing is disabled by default except when parsing Maven POMs where the default is to allow DTD processing but only to include a DTD snippet shipping with Ivy that is needed to deal with existing Maven POMs that are not valid XML files but are nevertheless accepted by Maven. Access can be be made more lenient via newly introduced system properties where needed. Users of Ivy prior to version 2.5.2 can use Java system properties to restrict processing of external DTDs, see the section about "JAXP Properties for External Access restrictions" inside Oracle's "Java API for XML Processing (JAXP) Security Guide".

CVE-2022-41967 (GCVE-0-2022-41967)

Vulnerability from cvelistv5 – Published: 2022-12-27 23:45 – Updated: 2025-04-14 16:23
VLAI
Title
Improper Restriction of XML External Entity Reference in Dragonfly
Summary
Dragonfly is a Java runtime dependency management library. Dragonfly v0.3.0-SNAPSHOT does not configure DocumentBuilderFactory to prevent XML external entity (XXE) attacks. This issue is patched in 0.3.1-SNAPSHOT. As a workaround, since Dragonfly only parses XML `SNAPSHOT` versions are being resolved, this vulnerability may be avoided by not trying to resolve `SNAPSHOT` versions.

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.
