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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-84860 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-84860 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-84860. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
