Description

The NETGEAR GS105PE Pro Safe Switch has a set of hard-coded credentials ('ntguser / debugpassword') that give access to several CGI control scripts and could allow a remote attacker to :

  • Modify the serial number and MAC address of the product. (produce_burn.cgi)

  • Manually set memory to a certain value and extract that value from it. (register_debug.cgi)

  • Upload new firmware. (bootcode_update.cgi)
