This analytic identifies attempts to exploit the CVE-2023-46805 and CVE-2024-21887 vulnerabilities in Ivanti Connect Secure. It detects GET requests to the `/api/v1/totp/user-backup-code/../../system/system-information` URI, which leverage an authentication bypass to access system information. The detection uses the Web datamodel to identify requests with a 200 OK response, indicating a successful exploit attempt. This activity is significant as it reveals potential unauthorized access to sensitive system information. If confirmed malicious, attackers could gain critical insights into the system, facilitating further exploitation and compromise.
The analytic identifies access to a specific Ivanti Connect Secure endpoint, `/api/v1/configuration/users/user-roles/user-role/rest-userrole1/web/web-bookmarks/bookmark`, which is known to be vulnerable to CVE-2023-46805 and CVE-2024-21887. It specifically looks for GET requests that result in a 403 Forbidden HTTP status code with an empty response body. This behavior is indicative of potential exploitation attempts against Ivanti Connect Secure systems. Successful exploitation could lead to unauthorized access or control, potentially resulting in data breaches or system compromise.
The analytic identifies attempts to exploit the CVE-2023-46805 and CVE-2024-21887 vulnerabilities in Ivanti Connect Secure. It detects POST requests to specific URIs that leverage command injection to execute arbitrary commands. The detection uses the Web datamodel to monitor for these requests and checks for a 200 OK response, indicating a successful exploit attempt. This activity is significant as it can lead to unauthorized command execution on the server. If confirmed malicious, attackers could gain control over the system, leading to potential data breaches or further network compromise.
