IXON VPN Client
TL;DR
View CSAF Summary Successful exploitation of this vulnerability could allow an attacker to perform remote code execution on the computer running the client with elevated privileges. The following versions of IXON VPN Client are affected: VPN Client <1.4.7 (CVE-2026-75925) CVSS Vendor Equipment Vulnerabilities
v3 9.6 IXON IXON VPN Client Improper Neutralization of CRLF Sequences ('CRLF Injection')
Background Critical Infrastructure Sectors: Commercial Facilities, Critical Manufacturing, Energy, Information Technology, Water and Wastewater Countries/Areas Deployed: Worldwide Company Headquarters Location: Netherlands Vulnerabilities Expand All + CVE-2026-75925 Improper Neutralization of CRLF Sequences (CWE-93) in IXON VPN Client before version 1.4.7 allows an attacker to execute commands as root or SYSTEM. Configuration values accepted by the local service are written to a file later consumed by a privileged subprocess, without line-ending sequences being neutralised, which allows additional directives to be introduced into that file. The configuration interface accepts changes without authenticating or verifying the origin of the requester (CWE-306, contributing). The injected configuration persists on disk across restarts of the client and the operating system, and the VPN connection continues to function normally, so there is no behavioral change visible to the user. View CVE Details Affected Products IXON VPN Client Vendor: IXON Product Version: IXON VPN Client: <1.4.7 Product Status: known_affected Remediations Mitigation IXON recommends updating the IXON VPN client to version 1.4.7 or later on every computer where it is installed. Mitigation As of August 5, 2026, IXON cloud rejects connections from clients below v1.4.7 at both the portal and the back-end API. Since the privileged subprocess and injected listener are only created when the client connects, unpatched installations cannot complete the exploit chain. Mitigation If the client is no longer need
