Ivanti Sentry Authentication Bypass Vulnerability
Ivanti · Sentry
A security vulnerability in the MICS Admin Portal of Ivanti MobileIron Sentry 9.18.0 and below stems from an insufficiently restrictive Apache HTTPD configuration. An attacker who can reach the administrative interface over the network can bypass its authentication controls without credentials and without any user interaction.
A security vulnerability in MICS Admin Portal in Ivanti MobileIron Sentry versions 9.18.0 and below, which may allow an attacker to bypass authentication controls on the administrative interface due to an insufficiently restrictive Apache HTTPD configuration.

This vulnerability was exploited by unauthenticated actors who accessed the System Manager Portal of Ivanti MobileIron Sentry via port 8433, leveraging an authentication bypass flaw to achieve remote code execution. This flaw allows attackers to access sensitive APIs, enabling them to change configurations, execute system commands, or write files onto the system. This vulnerability was part of a campaign involving cryptocurrency mining and internal network reconnaissance. The exploitation allowed attackers to deploy malicious tools and conduct unauthorized activities within the network, ultimately compromising system integrity and security.The exploitation facilitated unauthorized access to the Ivanti Sentry server, allowing the execution of OS commands as a system administrator using "sudo." Observations revealed that suspicious SSL connections over port 8433 led to HTTP GET requests, indicating the abuse of command-line utilities like wget and cURL.
