Description

ModSecurity is an open source cross platform web application firewall (WAF) engine for Apache IIS and Nginx. In versions 2.9.8 to before 2.9.11 an empty XML tag can cause a segmentation fault. If SecParseXmlIntoArgs is set to On or OnlyArgs and the request type is application/xml and at least one XML tag is empty (eg ) then a segmentation fault occurs. This issue has been patched in version 2.9.11. A workaround involves setting SecParseXmlIntoArgs to Off.
