CVE-2018-17190 : What You Need to Know

Apache Spark allows for code execution through the standalone resource manager, potentially leading to arbitrary code execution. This vulnerability affects all versions of Apache Spark.

Understanding CVE-2018-17190

Apache Spark's standalone resource manager can be manipulated to execute code on the 'master' host, which is not intended to run user code. However, a specially-crafted request can trigger code execution on the master, posing a security risk.

What is CVE-2018-17190?

In Apache Spark, the standalone resource manager can execute code on the 'master' host, contrary to its design. This vulnerability allows for arbitrary code execution through specially-crafted requests.

The Impact of CVE-2018-17190

The vulnerability enables attackers to execute code on the master host, potentially compromising the security of the system. This issue does not affect clusters with authentication enabled.

Technical Details of CVE-2018-17190

Apache Spark's vulnerability allows for unauthorized code execution on the master host, posing a significant security risk.
