Security vulnerability in RustDesk remote desktop client/server. One of 6+ critical CVEs affecting the open-source remote access platform.

RustDesk Server Pro through version 1.7.5 transmits sensitive address book credentials in cleartext over the network heartbeat synchronization API, enabling attackers to intercept and obtain authentication credentials without authentication. The vulnerability affects Windows, macOS, and Linux deployments where the address book sync functionality is enabled. No patch is currently available.

RustDesk Client through version 1.4.5 transmits sensitive preset address book credentials in cleartext during heartbeat synchronization, enabling network eavesdropping attacks across Windows, macOS, Linux, iOS, and Android platforms. An attacker positioned to intercept network traffic can capture authentication credentials by sniffing the unencrypted JSON payload. No patch is currently available for this high-severity vulnerability (CVSS 8.7).
