Explorance Blue versions prior to 8.14.12 use reversible symmetric encryption with a hardcoded static key to protect sensitive data, including user passwords and system configurations. This approach allows stored values to be decrypted offline if the encrypted data are obtained.
Weakness
The storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts.
