CVE-2025-2820Network attack vector

Service interruption via unlimited FTP mass uploads

Published Mar 26, 2025 · Updated Mar 26, 2025

Resource exhaustion in Bizerba GLx and CWx device firmware before 16.20 allows remote authenticated users to interrupt service via FTP uploads. The public FTP service accepts unlimited mass uploads without enforcing a storage quota, allowing the device's mass storage to become completely full. Valid FTP credentials and network access are required; exhausting storage compromises device availability without reported data disclosure or modification.
