XStream through 1.4.9, when a certain denyTypes workaround is not used, mishandles attempts to create an instance of the primitive type 'void' during unmarshalling, leading to a remote application crash, as demonstrated by an xstream.fromXML("<void/>") call.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - XStream through 1.4.9, when a certain denyTypes workaround is not used, mishandles attempts to create an     instance of the primitive type 'void' during unmarshalling, leading to a remote application crash, as     demonstrated by an xstream.fromXML(<void/>) call. (CVE-2017-7957)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - XStream through 1.4.9, when a certain denyTypes workaround is not used, mishandles attempts to create an
    instance of the primitive type 'void' during unmarshalling, leading to a remote application crash, as
    demonstrated by an xstream.fromXML("<void/>") call. (CVE-2017-7957)

According to its self-reported version number, the version of JFrog Artifactory installed on the remote host is prior to 7.10.1. It is, therefore, affected by multiple vulnerabilities:

  - Xstream API versions up to 1.4.6 and version 1.4.10, if the security framework has not been initialized, may     allow a remote attacker to run arbitrary shell commands by manipulating the processed input stream when     unmarshaling XML or any supported format. e.g. JSON. (CVE-2013-7285)

  - Multiple XML external entity (XXE) vulnerabilities in the Dom4JDriver, DomDriver, JDomDriver, JDom2Driver, SjsxpDriver,     StandardStaxDriver, and WstxDriver drivers in XStream before 1.4.9 allow remote attackers to read arbitrary files     via a crafted XML document. (CVE-2016-3674)

  - XStream through 1.4.9, when a certain denyTypes workaround is not used, mishandles attempts to create an instance     of the primitive type 'void' during unmarshalling, leading to a remote application crash, as demonstrated by     an xstream.fromXML call. (CVE-2017-7957)

  - The file name encoding algorithm used internally in Apache Commons Compress 1.15 to 1.18 can get into an infinite     loop when faced with specially crafted inputs. This can lead to a denial of service attack if an attacker can choose     the file names inside of an archive created by Compress. (CVE-2019-12402)

  - The OpenID client application in Atlassian Crowd before version 3.6.2, and from version 3.7.0 before 3.7.1     allows remote attackers to perform a Denial of Service attack via an XML Entity Expansion vulnerability. (CVE-2019-20104)

  - Go before 1.13.13 and 1.14.x before 1.14.5 has a data race in some net/http servers, as demonstrated by the     httputil.ReverseProxy Handler, because it reads a request body and writes a response at the same time. (CVE-2020-15586)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

It was discovered that XStream, a Java library to serialise objects to XML and back again, was suspectible to denial of service during unmarshalling.

It was discovered that there was a remote application crash vulnerability in libxstream-java, a Java library to serialize objects to XML and back again. This was due to mishandled attempts to create an instance of the primitive type 'void' during unmarshalling.

For Debian 7 'Wheezy', this issue has been fixed in libxstream-java version 1.4.2-1+deb7u2.

We recommend that you upgrade your libxstream-java packages.
