Executive ViewAI
Organizations using the ovpnmain.cgi script that allow attackers to inject malicious scripts should be aware of moderate risk from CVE-2019-25398, a cross-site scripting vulnerability rated CVSS 6.1. Attackers could inject scripts to steal sessions or perform actions as authenticated users. Proof-of-concept code is publicly available. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: implement CSP headers, enable HttpOnly cookies, deploy WAF XSS rules.
