Configuration disclosure and tampering via hardcoded key
Published Mar 23, 2026 · Updated Mar 23, 2026
Configuration encryption in TP-Link Archer NX200, NX210, NX500 and NX600 allows remote authenticated users to read and alter settings. The configuration mechanism uses one hardcoded cryptographic key to decrypt configuration files and re-encrypt modified data. Adjacent-network access and valid low-privilege credentials are required; the documented impact is limited to configuration confidentiality and integrity.
