Executive Summary

[{'type': 'paragraph', 'content': "CVE-2020-37163 is a SQL injection vulnerability found in QuickDate version 1.3.2. It occurs in the 'find_matches' endpoint through the '_located' parameter. Attackers can manipulate this parameter to inject UNION-based SQL statements, which allows them to extract sensitive information from the database."}, {'type': 'paragraph', 'content': "Specifically, the injection enables attackers to retrieve data such as database user credentials, the database name, and the system version. This is done by concatenating these pieces of information using SQL functions and receiving them in the server's response."}] [1, 2]

Detection Guidance

[{'type': 'paragraph', 'content': "This SQL injection vulnerability in QuickDate 1.3.2 can be detected by sending crafted POST requests to the /find_matches endpoint, specifically manipulating the '_located' parameter with UNION-based SQL payloads."}, {'type': 'paragraph', 'content': 'For example, a test command using curl might look like this:'}, {'type': 'list_item', 'content': "curl -X POST 'http://targetsite/find_matches' -d '_located=1 UNION ALL SELECT NULL, CONCAT_WS(0x3a, user(), database(), @@version), NULL-- ' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Cookie: your_session_cookie'"}, {'type': 'paragraph', 'content': 'If the server responds with database user, database name, and version information in the JSON response, it confirms the presence of the vulnerability.'}] [1]
