Descriptions
Certain TP-Link devices have a Hardcoded Encryption Key. This affects NC200 2.1.9 build 200225, N210 1.0.9 build 200304, NC220 1.3.0 build 200304, NC230 1.3.0 build 200304, NC250 1.3.0 build 200304, NC260 1.5.2 build 200304, and NC450 1.5.3 build 200304.
Determinados dispositivos TP-Link tienen una Clave de Cifrado Embebida. Esto afecta a NC200 versión 2.1.9 build 200225, N210 versión 1.0.9 build 200304, NC220 versión 1.3.0 build 200304, NC230 versión 1.3.0 build 200304, NC250 versión 1.3.0 build 200304, NC260 versión 1.5.2 build 200304, y NC450 versión 1.5.3 build 200304.
TP-LINK Cloud Cameras including products NC200, NC210, NC220, NC230, NC250, NC260, and NC450 suffer from having a hardcoded encryption key. The issue is located in the methods swSystemBackup and sym.swSystemRestoreFile, where a hardcoded encryption key is used in order to encrypt/decrypt a config backup file. The algorithm in use is DES ECB with modified s-boxes and permutation tables.
