Recently, NSFOCUS CERT found that Apache Hadoop officially fixed a command injection vulnerability. Since Apache Hadoop’s FileUtil.unTar API does not escape the input filename before passing it to the shell, an attacker could exploit this vulnerability to inject arbitrary commands and thus achieve remote code execution. Affected users are recommended to take steps to protect themselves.
Hadoop is an open source distributed computing platform under the Apache Foundation. It is developed based on the Java language, has good cross-platform features, and can be deployed in inexpensive computer clusters. Users can develop distributed programs without knowing the underlying details of distribution, and make full use of the power of clusters for high-speed computing and storage.
