Hardcoded Cryptographic Key in TP-Link Archer NX Configuration Encryption Mechanism
CVE-2025-15605 is a vulnerability in the configuration encryption mechanism of TP-Link Archer NX200, NX210, NX500, and NX600 routers caused by the use of a hardcoded cryptographic key. Because the same embedded key can be used to process configuration data, an authenticated attacker can decrypt protected configuration files, alter their contents, and then re-encrypt them into a form accepted by the device. This breaks the intended protection of stored or exported configuration data and allows unauthorized manipulation of router settings despite the presence of configuration encryption.
