Ivanti warned customers of a new critical Sentry API authentication bypass vulnerability tracked as CVE-2023-38035.
The software company Ivanti released urgent security patches to address a critical-severity vulnerability, tracked as CVE-2023-38035 (CVSS score 9.8), in the Ivanti Sentry (formerly MobileIron Sentry) product.
The vulnerability could be exploited to access sensitive API data and configurations, run system commands, or write files onto the system. The vulnerability CVE-2023-38035 impacts Sentry versions 9.18 and prior.
“If exploited, this vulnerability enables an unauthenticated actor to access some sensitive APIs that are used to configure the Ivanti Sentry on the administrator portal (port 8443, commonly MICS). While the issue has a high CVSS score, there is a low risk of exploitation for customers who do not expose port 8443 to the internet.” reads the advisory published by the company. Successful exploitation can be used to change configuration, run system commands, or write files onto the system. Ivanti recommends that customers restrict access to MICS to internal management networks and not expose this to the internet.”
