Changed	Description	Use of Password Hash With Insufficient Computational Effort, Cleartext Transmission of Sensitive Information vulnerability in rustdesk-client RustDesk Client rustdesk-client on Windows, MacOS, Linux, iOS, Android (Server Pro /api login over the HTTP management channel) allows Interception (aka Sniffing) followed by offline Password Brute Forcing. The controlled-host peer authentication channel is NOT affected: Client::secure_connection verifies the HBBS-signed host public key and negotiates an XSalsa20-Poly1305 secretbox session before the login proof is sent, so passive capture and relay man-in-the-middle do not expose it (capture-replay / CWE-294 withdrawn). On the Server Pro /api login path the proof is protected by TLS alone, is exposed under the automatic invalid-certificate downgrade (CVE-2026-30794), and is recoverable offline because it is a fast double SHA256 over a server-controlled salt and challenge with no slow KDF. This vulnerability is associated with program files src/client.rs and src/common.rs and program routines handle_hash(), handle_login_from_ui() (login proof construction) and post_request_() (API transport). This issue affects RustDesk Client: through 1.4.8.	Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.

Description

Improper Restriction of Excessive Authentication Attempts, Use of Password Hash With Insufficient Computational Effort vulnerability in rustdesk-server-pro RustDesk Server Pro rustdesk-server-pro on Windows, MacOS, Linux (Peer authentication, API login modules), rustdesk-server RustDesk Server (OSS) rustdesk-server on Windows, MacOS, Linux (Peer authentication, API login modules) allows Password Brute Forcing. This vulnerability is associated with program files src/server/connection.Rs and program routines Salt/challenge generation, SHA256(SHA256(pwd+salt)+challenge) verification.

This issue affects RustDesk Server Pro: through 1.7.5; RustDesk Server (OSS): through 1.1.15.
