AnyDesk < 9.0.5 Multiple Vulnerabilities

critical Nessus Plugin ID 298245

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of AnyDesk installed on the remote Windows host is prior to 9.0.5. It is, therefore, affected by multiple vulnerabilities:

- A denial of service vulnerability exists due to incorrect deserialization that results in failed memory allocation and a NULL pointer dereference. An unauthenticated, remote attacker can exploit this to cause the application to stop responding. (CVE-2025-27917)

- A heap-based buffer overflow vulnerability exists due to an integer overflow via a UDP packet during processing of an Identity user image within the Discovery feature, or when establishing a connection between any two clients. An unauthenticated, remote attacker can exploit this to execute arbitrary code.
(CVE-2025-27918)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to AnyDesk version 9.0.5 or later.
