Researchers Publish Working Exploit for Pre-Auth Any Desk Linux Flaw That Gives Root Access
Summary: Researchers published a working exploit on October 8, called AnyPwn, for a pre-authentication heap buffer overflow in AnyDesk Linux's session protocol that yields root access before any connection is approved. AnyDesk fixed the flaw in version 8.0.3 in June, describing it only as a crash bug, with no CVE assigned and no security advisory as of October 9.
What you should know: The published exploit works only against the 8.0.2 build over direct TCP port 7070, and the researchers say the same vulnerable code path is reachable through AnyDesk's relay servers, which they validated with a Frida trigger but did not fully chain. A root-level pre-auth flaw that shipped without a CVE or advisory leaves every administrator who reads changelogs for security signals with no signal at all.
