Description Adam Mariš 2016-06-01 09:21:35 EDT

It was found that OGNL expression language used by the Apache Struts framework has improper implementation of cache used to store method references. It's possible to prepare a DoS attack which can block access to a web site.

Comment 1 Adam Mariš 2016-06-01 09:22:50 EDT

Statement:

Not Vulnerable. This issue affects Struts 2 only; it does not affect the versions of struts as shipped with various Red Hat products.
