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":{"summary":"The flaw allows an authenticated user to bypass authorization and invoke any DWR method, leading to potential unauthorized access to restricted functionalities.","exploitability":"Exploitation is relatively easy for an authenticated user who can send a POST request with specific parameters to a permitted URL.","blast_radius":"If exploited, this could lead to significant data breaches or system compromise, as any DWR method can be invoked regardless of URL-based access controls.","remediation":"Upgrade to ScadaLTS 2.8.1-release-candidate build 1 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","ics"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-30T09:10:44.790Z"}}
