Hitachi Web Server 01-00 through 03-00-01, as used by certain Cosminexus products, does not properly validate SSL client certificates, which might allow remote attackers to spoof authentication via a client certificate with a forged signature.
The default configuration of the HTTP server in Hitachi IP5000 VOIP WIFI Phone 1.5.6 does not require authentication for sensitive configuration pages, which allows remote attackers to modify configuration.
