Security readout for executives and security teams
Symantec ProxyClient 3.4 for Windows has a local privilege escalation flaw. A malicious Windows user already on the machine could gain LocalSystem privileges and run code at the highest local level. This mainly raises the risk of compromised endpoints becoming fully controlled. Exposure appears limited to Windows systems running Symantec ProxyClient version 3.4. The bundle does not identify other affected versions, platforms, or products. Treat as high priority if ProxyClient 3.4 exists in the estate. The issue can convert local access into full system control, but available evidence does not show internet exposure or confirmed active exploitation. Mitigation focus: Inventory Windows endpoints for Symantec ProxyClient 3.4.; Review Symantec advisory SA152 for supported remediation guidance.; Prioritize vendor-supported update, replacement, or removal where applicable..
