Status: ModifiedCritical (9.8)—

A buffer overflow issue was discovered in the HMI3 Control Panel contained within the Swisslog Healthcare Nexus Panel, operated by released versions of software before Nexus Software 7.2.5.7. A buffer overflow allows an attacker to overwrite an internal queue data structure and can lead to remote code execution.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
