Summary
A vulnerability in the RBAC mechanism of SYS600 allows users with access to engineering tools to elevate their privileges to administrator level on the underlying Windows host, granting full control over the machine.
Risk Assessment
Unauthorized privilege escalation could lead to full compromise of the operating system and data stored on it.
Recommendation
Restrict access to engineering tools, implement the principle of least privilege, and regularly review user permissions.

- CVE-2026-9852Medium
A CSV injection vulnerability exists in SYS600. Injected malicious formulas can add or modify data to the spreadsheet, insert links, exfiltrate data, and in some cases, depending on how the user has their environment configured, execute malicious code on the user's machine. To exploit this issue attackers would need a way to create arbitrary log messages, achievable through normal functionality via SCIL scripts, a log injection vulnerability, or via the SYS600 broker.
