`Hello list!  
  
There are multiple vulnerabilities in Js-Multi-Hotel plugin for WordPress.   
Earlier I wrote about two other vulnerabilities.  
  
These are Abuse of Functionality, Denial of Service, Cross-Site Scripting   
and Full path disclosure vulnerabilities in Js-Multi-Hotel plugin for   
WordPress. There are much more vulnerabilities in this plugin (including   
dangerous holes), so after two advisories I'll write new advisories.

automated DoS and DDoS attacks with using of DAVOSET   
(http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2013-June/008850.html).
