CWE-611

In Dell EMC Unisphere for VMAX Virtual Appliance versions prior to 8.4.0.8, Dell EMC Solutions Enabler Virtual Appliance versions prior to 8.4.0.8, Dell EMC VASA Provider Virtual Appliance versions prior to 8.4.0.512, Dell EMC SMIS versions prior to 8.4.0.6, Dell EMC VMAX Embedded Management (eManagement) versions prior to and including 1.4.0.347, Dell EMC VNX2 Operating Environment (OE) for File versions prior to 8.1.9.231, Dell EMC VNX2 Operating Environment (OE) for Block versions prior to 05.33.009.5.231, Dell EMC VNX1 Operating Environment (OE) for File versions prior to 7.1.82.0, Dell EMC VNX1 Operating Environment (OE) for Block versions prior to 05.32.000.5.225, Dell EMC VNXe3200 Operating Environment (OE) all versions, Dell EMC VNXe1600 Operating Environment (OE) versions prior to 3.1.9.9570228, Dell EMC VNXe 3100/3150/3300 Operating Environment (OE) all versions, Dell EMC ViPR SRM versions 3.7, 3.7.1, 3.7.2 (only if using Dell EMC Host Interface for Windows), Dell EMC ViPR SRM versions 4.0, 4.0.1, 4.0.2, 4.0.3 (only if using Dell EMC Host Interface for Windows), Dell EMC XtremIO versions 4.x, Dell EMC VMAX eNAS version 8.x, Dell EMC Unity Operating Environment (OE) versions prior to 4.3.0.1522077968, ECOM is affected by a XXE injection vulnerability due to the configuration of the XML parser shipped with the product. XXE Injection attack may occur when XML input containing a reference to an external entity (defined by the attacker) is processed by an affected XML parser. XXE Injection may allow attackers to gain unauthorized access to files containing sensitive information or may be used to cause denial-of-service.

Apache Karaf provides a features deployer, which allows users to “hot deploy” a features XML by dropping the file directly in the deploy folder. The features XML is parsed by XMLInputFactory class. Apache Karaf XMLInputFactory class doesn’t contain any mitigation codes against XXE. This is a potential security risk as an user can inject external XML entities in Apache Karaf version prior to 4.1.7 or 4.2.2. It has been fixed in Apache Karaf 4.1.7 and 4.2.2 releases.

In Apache Tika 1.19 (CVE-2018-11761), we added an entity expansion limit for XML parsing. However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers, as per the documentation, removes the user-specified SecurityManager and thus removes entity expansion limits after the first parse. Apache Tika versions from 0.1 to 1.19 are therefore still vulnerable to entity expansions which can lead to a denial of service attack. Users should upgrade to 1.19.1 or later.

This affects Apache Cayenne 4.1.M1, 3.2.M1, 4.0.M2 to 4.0.M5, 4.0.B1, 4.0.B2, 4.0.RC1, 3.1, 3.1.1, 3.1.2. CayenneModeler is a desktop GUI tool shipped with Apache Cayenne and intended for editing Cayenne ORM models stored as XML files. If an attacker tricks a user of CayenneModeler into opening a malicious XML file, the attacker will be able to instruct the XML parser built into CayenneModeler to transfer files from a local machine to a remote machine controlled by the attacker. The cause of the issue is XML parser processing XML External Entity (XXE) declarations included in XML. The vulnerability is addressed in Cayenne by disabling XXE processing in all operations that require XML parsing.

In Apache Tika 0.1 to 1.18, the XML parsers were not configured to limit entity expansion. They were therefore vulnerable to an entity expansion vulnerability which can lead to a denial of service attack.

Xovis PC2, PC2R, and PC3 devices through 3.6.0 allow XXE.
