Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')

It was discovered that an internal Prosody library to load XML based on libexpat does not properly restrict the XML features allowed in parsed XML data. Given suitable attacker input, this results in expansion of recursive entity references from DTDs (CWE-776). In addition, depending on the libexpat version used, it may also allow injections using XML External Entity References (CWE-611).Show less

untangle is a python library to convert XML data to python objects. untangle versions 1.2.0 and earlier improperly restricts recursive entity references in DTDs. By exploiting this vulnerability, a remote unauthenticated attacker may cause a denial-of-service (DoS) condition on the server where the product is running.Show less

A vulnerability has been identified in Mendix Excel Importer Module (Mendix 8 compatible) (All versions < V9.2.2), Mendix Excel Importer Module (Mendix 9 compatible) (All versions < V10.1.2). The affected component is vulnerable to XML Entity Expansion Injection. An attacker may use this to compromise the availability of the affected component.Show less

An XML Entity Expansion (XEE) issue was discovered in Tryton Application Platform (Server) 5.x through 5.0.45, 6.x through 6.0.15, and 6.1.x and 6.2.x through 6.2.5, and Tryton Application Platform (Command Line Client (proteus)) 5.x through 5.0.11, 6.x through 6.0.4, and 6.1.x and 6.2.x through 6.2.1. An unauthenticated user can send a crafted XML-RPC message to consume all the resources of the server.Show less

Excel-Streaming-Reader is an easy-to-use implementation of a streaming Excel reader using Apache POI. Prior to xlsx-streamer 2.1.0, the XML parser that was used did apply all the necessary settings to prevent XML Entity Expansion issues. Upgrade to version 2.1.0 to receive a patch. There is no known workaround.Show less

XML Entity Expansion injection vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 September 2021 Update allows a local user to initiate high CPU and memory consumption resulting in a Denial of Service attack through carefully editing the EPDeploy.xml file and then executing the setup process.Show less

Opencast is a free and open source solution for automated video capture and distribution. Versions of Opencast prior to 9.6 are vulnerable to the billion laughs attack, which allows an attacker to easily execute a (seemingly permanent) denial of service attack, essentially taking down Opencast using a single HTTP request. To exploit this, users need to have ingest privileges, limiting the group of potential attackers The problem has been fixed in Opencast 9.6. There is no known workaround for this issue.Show less

redhat-certification 7 does not properly restrict the number of recursive definitions of entities in XML documents, allowing an unauthenticated user to run a "Billion Laugh Attack" by replying to XMLRPC methods when getting the status of an host.Show less

The Dashboard Editor in Hitachi Vantara Pentaho through 7.x - 8.x contains an XML Entity Expansion injection vulnerability, which allows an authenticated remote users to trigger a denial of service (DoS) condition. Specifically, the vulnerability lies in the 'dashboardXml' parameter. Remediated in >= 7.1.0.25, >= 8.2.0.6, >= 8.3.0.0 GAShow less

The XML parsers used by XMLBeans up to version 2.6.0 did not set the properties needed to protect the user from malicious XML input. Vulnerabilities include possibilities for XML Entity Expansion attacks. Affects XMLBeans up to and including v2.6.0.Show less

A vulnerability in the dashboard widget of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper restrictions on XML entities. An attacker could exploit this vulnerability by crafting an XML-based widget on an affected server. A successful exploit could cause increased memory and CPU utilization, which could result in a DoS condition.Show less

IBM InfoSphere Guardium 8.0, 8.01, and 8.2 is vulnerable to XML external entity injection, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability to obtain sensitive information. IBM X-Force ID: 78291.Show less
