Vulnerability from fkie_nvd - Published: 2025-09-09 09:15 - Updated: 2026-10-18 21:10
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
A vulnerability has been identified in SIMATIC PCS neo V4.1 (All versions), SIMATIC PCS neo V5.0 (All versions), SIMATIC PCS neo V6.0 (All versions < V6.0 SP1 Update 1), User Management Component (UMC) (All versions < V2.15.1.3). Affected products contain a stack-based buffer overflow vulnerability in the integrated UMC component. This could allow an unauthenticated remote attacker to execute arbitrary code or to cause a denial of service condition.
