Description
-A weakness could have allowed an authenticated Kiteworks Email Protection Gateway administrator to write a file outside its intended location and cause the application to execute it, potentially resulting in remote code execution as the underlying service account.
Published: 2026-09-30
Score: 7.2 High
EPSS: n/a
KEV: No
Impact: Remote Code Execution
Action: Immediate Patch
AI Analysis

Impact

The flaw is a path traversal condition that lets an authenticated administrator write a file outside the intended directory. The application then executes that file, giving the attacker the privileges of the underlying service account and enabling remote code execution.

Affected Systems

The vulnerability affects the Kiteworks Email Protection Gateway. No specific version or build information is provided, so all deployed instances of this gateway could be susceptible.

Risk and Exploitability

The CVSS score of 7.2 indicates a high impact with a required authenticated administrative attack vector. The EPSS score is unavailable and the CVE is not listed in the CISA KEV catalog. Because an attacker must be a legitimate administrator, the risk is mitigated to environments that tightly control administrative access, yet the potential to execute arbitrary code remains serious if these accounts are compromised.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Download and install the official patch released by Kiteworks for the Email Protection Gateway.
  • Limit administrative privileges to the smallest trusted user set and ensure the service account runs with the least privileges needed.
  • If a patch is not immediately available, restrict or disable the file creation functionality that the gateway exposes, and enforce strict input validation to prevent path traversal on all file upload channels.
