EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 99% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A privilege escalation security issue exists within FactoryTalk® Activation Manager. The security issue stems from custom actions in the installer that spawn visible console windows running with SYSTEM privileges during installation or repair operations. An authenticated attacker with Windows credentials could hijack these console windows to obtain a SYSTEM-level command prompt, allowing full access to all files, processes, and system resources.
