Security researchers at lgtm.com have discovered a critical remote code execution vulnerability (CVE-2017-9805) in Apache Struts affecting all versions of the popular application development framework since 2008.

The team that discovered the flaw stated that, “This particular vulnerability allows a remote attacker to execute arbitrary code on any server running an application built using the Struts framework and the popular REST communication plugin. The weakness is caused by the way Struts deserializes untrusted data.”.
