CVE-2026-84860 Details
Description
ScadaLTS 2.8.1-release-candidate build 0 is affected by an Authorization Bypass Spring Security gates DWR endpoints by URL path pattern, but DWR itself dispatches method calls based on the POST body parameters c0-scriptName and c0-methodName. 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. This is the systemic root cause that enables multiple other findings to be exploited as a low privilege user.
An authorization bypass vulnerability has been identified in ScadaLTS version 2.8.1-release-candidate build 0. This vulnerability affects the Direct Web Remoting (DWR) endpoints, allowing any authenticated user to invoke restricted DWR methods by exploiting the application's handling of POST body parameters. The vulnerability arises because the DWR 'crossDomainSessionSecurity' setting is disabled, removing essential origin validation. As a result, low-privilege users can access restricted classes through permitted URLs, bypassing URL-based access controls.
At the time of publication, no fixed version is available. Users should contact Scada-LTS for guidance on obtaining a version that addresses this vulnerability.
