AI risk analysis

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.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to ScadaLTS 2.8.1-release-candidate build 1 or later.

NVD 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.
