Overview

Description
ScadaLTS 2.8.1-release-candidate build 0 is affected by an Authenticated Blind SQL Injection The /api/events/search endpoint accepts a JSON body containing a sortBy array. The values in this array are concatenated directly into the SQL ORDER BY clause without any sanitization or parameterization. This allows authenticated users with the ROLE_USER role to perform time-based and boolean-based blind SQL injection to extract arbitrary data from the database, including password hashes of all users. The endpoint is accessible to any authenticated user with ROLE_USER, ROLE_ADMIN, or ROLE_PUBLIC via POST /api/events/search as defined in spring-security.xml.

  1. The Ignition Perspective module does not properly validate session privileges when determining Designer-level access. An authenticated user with access to a Vision project could provide their valid Vision session identifier and gain Designer-level privileges. An attacker could exploit these elevated privileges to execute arbitrary code in the context of the Ignition Gateway process.•CVE-2026-92817
  2. Autonomy Logic OpenPLC 3 is susceptible to an improper neutralization of input during web page generation vulnerability when the web interface attempts to route the program based on a query string parameter with no encoding.•CVE-2026-88020
  3. ScadaLTS 2.8.1-release-candidate build 0 is affected by an Authenticated Remote Code Execution via Scripting Sandbox Bypass The DWR "DataSourceEditDwr" class exposes the "validateScript" method that compiles and executes attacker-supplied JavaScript via the Rhino scripting engine. There are no authorization checks on this method and so it is possible for an attacker with access to a low privilege user to abuse this flaw by leveraging the DWR routing bypass.•CVE-2026-84858
  4. 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.•CVE-2026-84860
  5. A security issue exists within FactoryTalk® Historian Machine Edition. An attacker with low-level authentication could exploit this vulnerability to achieve remote code execution on the affected device.•CVE-2025-12768
