A Kiteworks appliance setup interface did not confine a user-supplied file path to its intended directory, which could allow an unauthenticated attacker to write a file to any location writable by the affected service account, potentially compromising the integrity of the appliance or rendering it unavailable until an operator intervenes. Exploitation requires network access to the affected interface, which is not reachable on a fully configured appliance in its default configuration; reaching it depends on either the transient window while an appliance is first being provisioned or a non-default appliance configuration.

VA-26-274-01 — Kiteworks multiple vulnerabilities

Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to a path traversal weakness in an administrative import function allowed an authenticated administrator to write files to arbitrary locations on the server. This could potentially be leveraged to execute arbitrary code on the underlying system. Kiteworks Core before version 9.5.1 is vulnerable to Content Injection. A URL parameter in the PDF viewer was insufficiently validated, allowing an attacker-controlled document to be loaded and displayed under the trust of the legitimate application domain. This could increase the credibility of phishing attempts relying on malicious links embedded in the displayed content. Kiteworks Secure Data Forms before version 9.5.0 is vulnerable to Server-Side Request Forgery that could allow an unauthenticated, remote attacker to make the server issue arbitrary outbound network requests and read back the responses. This could potentially be used to reach internal-only services or other network-restricted resources. Kiteworks Core before version 9.5.0 is vulnerable to Stored Cross-site Scripting (XSS) that could allow an authenticated user to store crafted content that executes arbitrary JavaScript in another user's authenticated session when they preview shared content. This could potentially lead to session compromise and account takeover. Kiteworks Core before version 9.5.0 is vulnerable to Improper Privilege Management and does not correctly enforce restrictions on role…
