CVE-2021-39139
Assigner: GitHub_M
Published: 2021-08-23T17:50:14
State: PUBLISHED
affected: product: xstream
vendor: x-stream
versions: status: affected
version: < 1.4.18
descriptions: value: XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. A user is only affected if using the version out of the box with JDK 1.7u21 or below. However, this scenario can be adjusted easily to an external Xalan that works regardless of the version of the Java runtime. 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.
