CVE-2025-34499

AnyDesk before 8.0.3 allows unauthenticated remote attackers to execute arbitrary code via a heap-based buffer overflow, as demonstrated on Linux for command execution as root without the victim approving desktop control. In the stream packet handler for mode 5 in the session protocol, a payload length value is not validated.

AnyDesk before 3.6.1 on Windows has a DLL injection vulnerability.

A vulnerability in AnyDesk allows a local attacker to cause a denial-of-service (DoS) condition by abusing the 'Send Support Information' feature. The attack requires prior low-privileged code execution on the target system.

A vulnerability in AnyDesk allows a local attacker to cause a denial-of-service (DoS) condition by manipulating screen recording files. The attacker must first obtain the ability to execute low-privileged code on the target system.

AnyDesk version 2.5.0 contains an unquoted service path vulnerability that allows local users to execute arbitrary code with SYSTEM privileges by exploiting the service installation. Attackers can insert malicious executables in the system root path that execute with elevated privileges during application startup or system reboot.

AnyDesk 7.0.9 allows a local user to gain SYSTEM privileges via a symbolic link. The user can write to their own %APPDATA% folder (used for ad.trace and chat), but the product runs as SYSTEM when writing chat-room data there.
