CVE-2026-102117: Kiteworks Core remote code execution in remote-support functionality

CVE-2026-102117 · Severity: high · CVSS 7.2 · Published 2026-09-30

Kiteworks Core is a secure data gateway platform used for sensitive file transfer and collaboration. An authenticated system administrator with access to an encryption key used in remote support can redirect the system's outbound support connection to an attacker-controlled server, allowing arbitrary OS command execution with local service account privileges. This could lead to complete system compromise and data exfiltration.

Technologies: Kiteworks Core. Vendors: Kiteworks.

Technical details

A high-privilege authentication bypass in the remote-support capability allows authenticated administrators to redirect outbound connections and execute arbitrary OS commands. The vulnerability stems from improper verification of the destination of support connections (CWE-940) and reliance on untrusted inputs in security decisions (CWE-807). It requires the attacker to be an authenticated System Administrator with the encryption key, but achieves unauthenticated remote code execution on the underlying system once the redirect is established.
