Apache Tomcat - Remote Code Execution (CVE-2017-12617)

Apache Tomcat is affected by a Remote Code Execution vulnerability. The root cause of this vulnerability consists in using a bad servlet context configuration with readonly=false and the PUT method allowed. Therefore, an unauthenticated remote attacker can use PUT method to upload JSP files on the server and execute them.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.

Upgrade the Apache Struts to the latest version or to a version higher than: 9.0.0, 8.5.22, 8.0.46, 7.0.81.
