CVE-2011-5057

Apache Struts 2.3.1.2 and earlier, 2.3.19-2.3.23, provides interfaces that
do not properly restrict access to collections such as the session and
request collections, which might allow remote attackers to modify run-time
data values via a crafted parameter to an application that implements an
affected interface, as demonstrated by the SessionAware, RequestAware,
ApplicationAware, ServletRequestAware, ServletResponseAware, and
ParameterAware interfaces. NOTE: the vendor disputes the significance of
this report because of an “easy work-around in existing apps by configuring
the interceptor.”
