Overview

Toshiba Global Commerce Solutions' 4690 Point of Sale operating system contains a password hashing algorithm that can be reversed. (CWE-328)

Description

Toshiba Global Commerce Solutions' 4690 Point of Sale operating system contains a password hashing algorithm that can be reversed. (CWE-328) The ADXCRYPT algorithm that may be used for password hashing on the 4690 operating system is susceptible to known-plaintext attacks and hash collisions.

Additional details about this vulnerability may be found in Security Bulletin R1005054.

Use a LDAP server for authentication
4690 OS version V6R3 or later has the option to use an LDAP server for authentication. This method will use whatever hashing algorithm the LDAP server uses.
