The crossDomainSessionSecurity setting in web.xml is set to false, which disables DWR's built-in origin validation. This means any authenticated user can invoke any DWR method (regardless of the URL-based access control) by sending their request to a URL they are permitted to access (e.g. MiscDwr.initializeLongPoll.dwr) while targeting a restricted class in the POST body.\n\n\n\nThis is the systemic root cause that enables multiple other findings to be exploited as a low privilege user.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
