AnyDesk auth bypass

AnyDesk has had authentication and client vulnerabilities, including weaknesses in how connection and unattended passwords are handled and client-side flaws, plus the risk from a supply-chain incident affecting its signing. Against an affected version these allow unauthorised connection or action, and recovered stored credentials enable durable access independent of password guessing.

In February 2024, AnyDesk disclosed evidence that some production systems had been compromised and stated that its remediation included replacing the code-signing certificate. This is important incident and software-trust context, but the disclosure did not establish an AnyDesk authentication bypass or distribution of malicious official clients. AnyDesk's later guidance states that clients obtained from official sources remained safe despite the certificate change. Treat authentication flaws separately and require a specific advisory, affected version, and reproducible mechanism before calling an issue a bypass.

bash

# inventory local AnyDesk configuration and identifiers
dir "%APPDATA%\AnyDesk" "%ProgramData%\AnyDesk" 2>nul
type "%PROGRAMDATA%\AnyDesk\service.conf" 2>nul
# this does not itself recover an unattended password or demonstrate an auth bypass

Exploitation notes#

Configuration files can reveal installation details, the device ID, service settings, and policy-relevant state. Password recovery requires separate, version-specific evidence.
For any claimed client or authentication flaw, fingerprint the build and match it to a concrete advisory before describing impact.
Validate software origin and signing state according to AnyDesk's incident guidance, while avoiding unsupported conclusions about official binaries.
