Last updated on: 2026-03-24

Assigner: VulnCheck

Description
Green CMS 2.x contains an SQL injection vulnerability that allows authenticated attackers to execute arbitrary SQL queries by injecting malicious code through the cat parameter. Attackers can send GET requests to index.php with m=admin, c=posts, a=index parameters and inject SQL code in the cat parameter to manipulate database queries and extract sensitive information.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2019-25573 is a SQL injection vulnerability in Green CMS version 2.x. It allows authenticated attackers to inject malicious SQL code through the "cat" parameter in a GET request to the admin posts module (index.php with parameters m=admin, c=posts, a=index). This injection enables attackers to execute arbitrary SQL queries on the backend database.'}, {'type': 'paragraph', 'content': 'The vulnerability exploits improper neutralization of special elements used in SQL commands, allowing attackers to manipulate database queries and potentially extract sensitive information.'}] [1, 2]

Detection Guidance

[{'type': 'paragraph', 'content': 'This SQL injection vulnerability in Green CMS 2.x can be detected by sending crafted GET requests to the vulnerable endpoint and observing the response behavior.'}, {'type': 'paragraph', 'content': "A common detection method is to use a time-based blind SQL injection payload in the 'cat' parameter to cause a measurable delay in the server response."}, {'type': 'paragraph', 'content': 'For example, you can send a request like:'}, {'type': 'list_item', 'content': "GET /index.php?m=admin&c=posts&a=index&cat=1')) AND 1=BENCHMARK(100000000,MD5(0x456665))-- -"}, {'type': 'paragraph', 'content': 'If the server response is significantly delayed compared to a normal request, it indicates the presence of the SQL injection vulnerability.'}] [1]
