CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

A vulnerability was found in XStream. Parsing a maliciously crafted file could cause the application to crash.

The processed stream at unmarshalling type contains type information to recreate the formerly written objects. XStream creates therefore new instances based on these type information. The crash occurrs if this information advices XStream to create an instance of the primitive type 'void'. This situation can only happen if an attacker was able to manipulate the incoming data, since such an instance does not exist.

It was found that XStream could deserialize arbitrary user-supplied XML content, representing objects of any type. A remote attacker able to pass XML to XStream could use this flaw to perform a variety of attacks, including remote code execution in the context of the server running the XStream application.

XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

Impact The vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.17.

Workarounds See workarounds for the different versions covering all CVEs.
