Technical details
This vulnerability is classified as an improper link resolution (CWE-59) flaw within the screen recording component of AnyDesk. The root cause is the application's failure to properly validate file paths when handling recording files, allowing a local attacker to create directory junctions. By exploiting this, a low-privileged user can trick the high-privileged AnyDesk service into creating arbitrary files in sensitive system locations. This capability can be leveraged to trigger a denial-of-service (DoS) condition. The attack requires local code execution and carries a high complexity due to the specific timing or environmental conditions needed to redirect the file operations.
