The default configuration of the Resources plugin 1.0.0 before 1.2.6 for Pivotal Grails 2.0.0 through 2.3.6 does not properly restrict access to files in the META-INF directory, which allows remote attackers to obtain sensitive information via a direct request. NOTE: this issue was SPLIT from CVE-2014-0053 due to different researchers per ADT5.
