# Exploit Title: ManageEngine EventLog Analyzer 10.0 - Information Disclosure # Date: 2020-02-23 # Author:Scott Goodwin # Vendor: https://www.manageengine.com/ # Software Link: https://www.manageengine.com/products/eventlog/ # CVE: CVE-2019-19774 Vulnerability Name: Authenticated Information Disclosure in ManageEngine EventLog Analyzer Registered: CVE-2019-19774 Discoverer: Scott Goodwin, OSCP OCD Tech Vendor of Product: ManageEngine Affected Product Code Base: EventLog Analyzer - 10.0 SP1 Affected Component: Affected ManageEngine endpoint: http://exampleclient:8400/event/runquery.do This endpoint allows the ManageEngine user to execute commands against the ManageEngine PostgreSQL database. Attack Type: Remote Vulnerability Type: Incorrect Access Control Vulnerability Impact: Authenticated Information Disclosure Attack Vector: To exploit the vulnerability, an authenticated user must execute a specially crafted query against the ManageEngine database to bypass the built-in security controls and extract credential data. Vulnerability Description: An issue was discovered in Zoho ManageEngine EventLog Analyzer 10.0 SP1. By running "select hostdetails from hostdetails" at the /event/runquery.do endpoint, it is possible to bypass the security restrictions that prevent even administrative users from viewing credential data stored in the database, and recover the MD5 hashes of the accounts used to authenticate the ManageEngine platform to the managed machines on the network (most often administrative accounts). Specifically, this bypasses the following restrictions: a query cannot mention "password", and a query result cannot have a "password" column. PoC: Run the database query: "select hostdetails from hostdetails" at the /event/runquery.do endpoint Reporting Timeline: 10/30/2019: This vulnerability was reported to ManageEngine via the Zoho/ManageEngine Bug Bounty program. They acknowledged the initial report. 12/12/2019: Vulnerability registered 12/13/2019: Vulnerability acknowledged and update (12110) made available to ManageEngine customers. 12/13/2019: Public disclosure Additional Information: This query bypasses the following security restrictions implemented within Manage Engine: 1. restrictions on queries that include the word "password". This query will output the value stored in the "password" field, without the word "password" actually appearing in the query. If the query contains the word "password" Manage Engine will not execute the query. 2. restrictions on printing the password field to the screen in a column called "password". If the results of the query include a columncalled "password", Manage Engine will mask the password with a series of asterisks "". This query will output the entire contents of the table, without formatting is as a table within the web interface, which leads to bypass of this security control.
