CVE-2026-19656: CWE-862 in SCADA-LTS ScadaLTS
ScadaLTS 2.7.8.1 exposes a server-side method that lacks authorization checks, allowing any authenticated user (including one holding only low-privilege, read-only permissions) to execute arbitrary operating system commands on the host. Successful exploitation results in code execution in the context of the ScadaLTS server process (root), leading to full compromise of the underlying system.
AI Analysis
Technical Summary
CVE-2026-19656 affects ScadaLTS version 2.7.8.1 and involves a missing authorization check on a server-side method. This allows authenticated users with minimal privileges to execute arbitrary OS commands as root on the host running the ScadaLTS server. The vulnerability is classified under CWE-862 (Improper Authorization) and has a critical CVSS 3.1 base score of 9.9. The flaw enables complete compromise of the underlying system by unauthorized command execution. No patch or official remediation has been disclosed by the vendor, and the product is not a cloud service, so remediation depends on vendor updates or workarounds.
Potential Impact
Successful exploitation results in arbitrary code execution with root privileges on the host running ScadaLTS 2.7.8.1. This leads to full system compromise, including confidentiality, integrity, and availability impacts. Attackers with only low-privilege authenticated access can escalate to full control of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to authenticated users and monitor for suspicious activity. Consider isolating the ScadaLTS server to limit exposure. No vendor-provided temporary fixes or workarounds are currently documented.
