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.
AnalysisAI
RustDesk Client through version 1.4.5 on Windows, macOS, and Linux uses weak password hashing and improper object prototype handling in its password security and configuration encryption modules, allowing local authenticated attackers to extract embedded sensitive data including passwords and machine identifiers. The vulnerability affects critical cryptographic functions including symmetric_crypt() and decrypt_str_or_original(), enabling attackers with local access and valid credentials to compromise encrypted credentials and system identifiers. …
