RustDesk Encrypts Local Passwords with World-Readable Machine ID and Fixed Zero Nonce (XSalsa20-Poly1305)
Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), Use of Password Hash With Insufficient Computational Effort vulnerability in rustdesk-client RustDesk Client rustdesk, hbb_common on Windows, MacOS, Linux (Password security module, config encryption, machine UID modules) allows Retrieve Embedded Sensitive Data. This vulnerability is associated with program files hbb_common/src/password_security.Rs, hbb_common/src/config.Rs, hbb_common/src/lib.Rs (get_uuid), machine-uid/src/lib.Rs and program routines symmetric_crypt(), encrypt_str_or_original(), decrypt_str_or_original(), get_uuid(), get_machine_id().
This issue affects RustDesk Client: through 1.4.5.

The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
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.
Nonces should be used for the present occasion and only once.
The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive.
