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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://www.tenable.com/security/research/tra-2026-60","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
