YASRV (Yet Another Struts RCE Vulnerability) yes a different one from yesterday

Yesterday saw CVE-2017-9805, today we have a new remote code execution vulnerability in Apache Struts 2 which is CVE-2017-12611. Yesterdays was in the REST API and related to Java XML unsafe deserializarion. Todays relates to using Freemarker in your application. Both should encourage you to patch.

Current versions are Struts 2.3.34 and Struts 2.5.13.

Cheers,
Adrien de Beaupré, SANS Instructor and #SEC642 Co-author
