路径说明

由于 catalina.jar中的 org.apache.catalina.webresources.StandardRoot.class的 getResource方法的 validate存在过滤和限制,所以可遍历路径均在 /WEB-INF

可读取的文件大致如下

#WEB-INF下
decorators.xml
glue-config.xml
server-config.wsdd
sitemesh.xml
urlrewrite.xml
web.xml
#/WEB-INF/classes下
confluence-filtered-frames.properties
confluence-init.properties
crowd.properties(较为重要)
hash-registry.properties
lgplTemplate.soy
log4j-diagnostic.properties
log4j.properties
logging.properties
mime.types
osuser.xml
seraph-config.xml
seraph-paths.xml
velocity_implicit.vm
velocity.properties
