Senserva AI Opinion for CVE-2023-38035
CVE-2023-38035 lets an attacker reach the Ivanti Sentry (formerly MobileIron Sentry) administrative interface without authenticating, because the Apache HTTPD configuration is insufficiently restrictive. Anyone running Sentry with its admin port exposed is at risk, and this flaw carries a maximum EPSS score of 100 percent, sits in CISA KEV since 2023-08-22, and has been used in ransomware campaigns. The admin interface is the control plane for mobile device management, so a bypass hands attackers a high value foothold.
Do this: Restrict access to the Sentry administrative interface (typically port 8443) to trusted management networks and apply Ivanti's patch for CVE-2023-38035 immediately.
