# Affected version: 2.2.1.4 ##########################################
# #
# Summary: The CSL 1010 M2M 3G WiFi Module is ########################
# a portable 3G/LTE router that stores its ###########################
# configuration in a backup file (Router.cfg). #######################
# #
# Desc: The device protects its configuration ########################
# file (Router.cfg) with a weak/insecure #############################
# obfuscation (single-byte XOR cipher) using #########################
# a static key (0xEC) instead of real encryption. ####################
# Because the same key is applied to the entire ######################
# file, it is trivially recovered and the ############################
# configuration can be decoded back to cleartext #####################
# with a few lines of code. This discloses ###########################
# all stored secrets in plaintext, including #########################
# the web administration and telnet passwords, #######################
# the WPA/WPA2 pre-shared key, PPPoE/3G/APN ##########################
# credentials, and SIM identifiers (IMSI/IMEI). ######################
