Title

RustDesk Encrypts Local Passwords with World-Readable Machine ID and Fixed Zero Nonce (XSalsa20-Poly1305)

Summary

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.

Severity ?
