What is CVE-2026-75925?
CVE-2026-75925 is a critical command injection vulnerability in IXON VPN Client, published on 4 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-93
