Title

Scada-LTS DWR Authorization Bypass - Systemic

Summary

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.

Vulnerability from github – Published: 2026-09-16 15:31 – Updated: 2026-09-17 21:31

Details

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.

Severity

8.8 (High)
