Kiteworks did not enforce the maximum permitted value for a configurable security-policy setting. An authenticated administrator could set this value outside its intended range so that the associated control never activated, while the control continued to appear enabled in the administrative interface and audit log, allowing it to be silently rendered ineffective.

A privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root and run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.

A privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root. A privileged routine did not safely handle a filesystem path that the lower-privileged account could influence, allowing the attacker to cause a root-owned operation to run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.

A command injection vulnerability in Kiteworks could allow a high-privileged authenticated administrator to execute arbitrary operating-system commands as root on the affected appliance node. Successful exploitation requires an administrative account with elevated privileges.

Kiteworks Core contains a business logic flaw in a Kiteworks file-request feature allowed an authenticated user to send a request that appeared to originate from another user, because the server did not verify that the requester was authorized to act as the specified account. This could be used to solicit files or information from a recipient under a trusted identity; exploitation requires the feature to be enabled for the attacker's profile and the targeted recipient to act on the request.

Kiteworks Core before version 9.5.0 is vulnerable to OS Command Injection that allows an authenticated administrator to upload a configuration package whose contents were not sufficiently validated before being processed. A crafted package could cause the underlying system to execute arbitrary operating-system commands, potentially with elevated privileges, on the affected appliance.

Kiteworks Core before version 9.5.0 is vulnerable to SQL Injection. A stored SQL injection vulnerability in a Kiteworks administrative reporting feature could allow an authenticated administrator to read sensitive data from the underlying database and to affect the availability of the service. Exploitation requires an existing, authenticated administrative account with access to the affected reporting function.

Kiteworks Core before version 9.5.0 is vulnerable to Arbitrary File Write. An improper restriction of a user-supplied file path in a Kiteworks administrative export feature could allow an authenticated administrator to write a file to an arbitrary location on the underlying host, potentially leading to command execution on the appliance. Exploitation requires an existing, authenticated administrative account with access to the affected export function.

Kiteworks Core before version 9.5.0 is vulnerable to Stored Cross-Site Scripting. A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an authenticated user to submit content that, when later viewed by another user, executes arbitrary JavaScript in that user's authenticated session. This could be used to perform actions on the victim's behalf and may have permitted account takeover, including of higher-privileged users. Exploitation requires the victim to view the attacker-supplied content.
