CVE-2026-75925: IXON VPN Client lets attackers run code as admin
CVE-2026-75925 · published today
Summary
The IXON VPN client (versions before 1.4.7) can be tricked into adding extra commands to its own configuration file. Because the client does not check who is making changes, an attacker could insert commands that run with the highest system privileges, and the changes remain even after a restart. Update the client to the latest version or reinstall it to eliminate this risk.
What to do
- Update ixon ixon vpn client to version 1.4.7 or later.

Original advisory text
IXON VPN Client CRLF Injection
Improper neutralization of CRLF sequences 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 neutralized, which allows additional directives to be introduced into that file. The configuration interface accepts changes without authenticating or verifying the origin of the requester. 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.
