ZDI-26-401: (0Day) AnyDesk Support Information Link Following Denial-of-Service Vulnerability
This vulnerability allows local attackers to create a denial-of-service condition on affected installations of AnyDesk. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 4.7. The following CVEs are assigned: CVE-2026-15682.
AI Analysis
Technical Summary
This vulnerability in AnyDesk allows local attackers who already have the ability to execute low-privileged code to cause a denial-of-service condition by exploiting the Send Support Information feature. The exploit involves creating a junction to manipulate the service into creating arbitrary files, disrupting normal operation. The vulnerability was reported to the vendor in March 2025, but as of the advisory publication in July 2026, no official fix or patch has been provided. The vendor has not taken ownership of the issue, and the Zero Day Initiative published the advisory as a 0-day. The CVSS rating assigned is 4.7 (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H).
Potential Impact
Successful exploitation results in a denial-of-service condition on affected AnyDesk installations. There is no impact on confidentiality or integrity. The attacker must have local low-privileged code execution to exploit this vulnerability, limiting the attack scope.
Mitigation Recommendations
No official fix or patch is currently available. The vendor has not provided remediation. The primary mitigation is to restrict interaction with the AnyDesk product to trusted users only, minimizing the risk of local code execution by untrusted parties.
