| Descripción | `dmCorePlugin/lib/basic/dmString.php` implements `dmString::random()` by repeatedly calling PHP `rand()`. The password-reset action in `dmCorePlugin/plugins/dmUserPlugin/modules/dmUser/lib/BasedmUserActions.class.php` uses a 12-character value from this function as a bearer `forgot_password_code`, and the persistent-login path in `dmSecurityUser.class.php` derives its remembered-login key from the same output. The reset handler accepts the code to set a new password, while `dmRememberMeFilter` authenticates a request based on a matching key. These account-authentication tokens are generated by a non-cryptographic PRNG rather than a CSPRNG, so deployments where an attacker can predict or recover the PRNG state are exposed to account takeover. |
