CVE-2026-102099: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Kiteworks Core
Kiteworks Core versions before 9.5.0 contain a path traversal vulnerability in an administrative export feature. This flaw allows an authenticated administrator to write files to arbitrary locations on the host system. Successful exploitation could lead to command execution on the appliance. The vulnerability requires an existing administrative account with access to the export function.
AI Analysis
Technical Summary
CVE-2026-102099 is a path traversal vulnerability (CWE-22) in Kiteworks Core prior to version 9.5.0. It arises from improper limitation of user-supplied file paths in an administrative export feature, enabling an authenticated administrator to perform arbitrary file writes. This can potentially lead to command execution on the underlying host system. Exploitation requires high privileges (authenticated admin) and access to the affected export functionality.
Potential Impact
An attacker with an authenticated administrative account can write files to arbitrary locations on the host, potentially leading to full command execution on the appliance. This compromises confidentiality, integrity, and availability of the system. The CVSS 3.1 score is 7.2 (high severity), reflecting network attack vector, low attack complexity, high privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
A fixed version 9.5.0 is available that addresses this vulnerability. Users should upgrade Kiteworks Core to version 9.5.0 or later to remediate this issue. No other mitigation or workaround is indicated. Since this is not a cloud service, remediation depends on user upgrade.
