Struts 2 OGNL Double Evaluation RCE
Security Research Laboratory : Struts 2 Remote ...
A Coverity write-up of the Struts 2 wildcard-mapping RCE: an action name of the form ${...} or %{...} reaches StrutsResultSupport.conditionalParse and is evaluated a second time as OGNL, so a URL alone reaches Runtime.exec. JavaSnoop tracing pins the sink, and the same double evaluation is found in HttpHeaderResult and DefaultUrlHelper. Fixed in 2.3.14.2.
