Detailsinfo

A vulnerability classified as problematic was found in rustdesk-client RustDesk Client up to 1.4.5. This vulnerability affects the function symmetric_crypt/encrypt_str_or_original/decrypt_str_or_original/get_uuid/get_machine_id in the library hbb_common/src/lib.Rs of the file hbb_common/src/password_security.Rs of the component UID Module. The manipulation with an unknown input leads to a password recoverable vulnerability. The CWE definition for the vulnerability is CWE-257. 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. As an impact it is known to affect confidentiality. CVE summarizes:

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.
