CVE-2017-12615

Apache Tomcat

When running Apache Tomcat on Windows with HTTP PUTs enabled, it is possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • It is known to have been used in ransomware campaigns.
  • US federal civilian agencies are required to remediate it by 2022-04-15. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply updates per vendor instructions.
