false positives are not expected, as this detection is based on monitoring http post requests to a specific endpoint with a status code of 200. however, ensure that legitimate requests to the `/wsstatusevents/eventhandler.asmx` endpoint are accounted for in the environment to avoid false positives.

Description

This detection identifies potential exploitation of a critical SQL injection vulnerability in Ivanti Endpoint Manager (EPM), identified as CVE-2024-29824. The vulnerability, which has a CVSS score of 9.8, allows for remote code execution through the RecordGoodApp function in the PatchBiz.dll file. An attacker can exploit this vulnerability by manipulating the goodApp.md5 value in an HTTP POST request to the /WSStatusEvents/EventHandler.asmx endpoint, leading to unauthorized command execution on the server. Monitoring for unusual SQL commands and HTTP requests to this endpoint can help identify exploitation attempts. Note that, the detection is focused on the URI path, HTTP method and status code of 200, indicating potential exploitation. To properly identify if this was successful, TLS inspection and additional network traffic analysis is required as the xp_cmdshell comes in via the request body.
